Hubei Huangshi is the birthplace of China's bronze culture, and is listed as a national key cultural relic protection site. Huangshi Tongluoshan Ancient Copper Mine Site is famous both at home and abroad. Yellowstone Daye had its name in the Tang Dynasty as a result of "big Xingxing Smelting." “The fire is shining in the sky, the red star is purple smoke,†and has continued for thousands of years, highlighting the features of non-ferrous mining and metallurgy with high energy consumption and high emissions. The high-carbon economy is obviously not sustainable. With the constant shortage of energy, the community’s appeal for environmental protection has become increasingly strong, and with the inclusion of Huang Shi in resource-exhausted cities, the transformation of the economic growth mode is imminent. Although Huangshi is known as the “Three Chu Copper Capitalsâ€, the R&D and production of high-precision copper strips has been left blank. At this time, a young company took on this important historic task in the region, in the industry, and in the country.
Chinalco Huazhong Copper: Efforts to create "low-carbon green" enterprises in the city of Jiangnan Mining and Metallurgy - Hubei Huangshi, Chinalco Huazhong Copper Company as a young enterprise, with a unique charm, interpretation of the "low-carbon, environmental protection The concept of "shows the world the charm of green civilization." In the plant area, there are mountains and rivers, and the trees are luxuriant; the staff dormitory is called “The springs return to shallow rocks and the high willows, and the vines move between the green vines.†In the 500-meter-long main building, various high, refined, and pointed equipments sing and sing. The purple and bright copper belts spit out; there are few people in the operation area, and there is no visible heat and noisy scene. Over the past few years, nearly 60 people including provincial and ministerial leaders including the vice premier of the State Council, the vice chairman of the National Committee of the People's Republic of China, and the deputy director of the National Committee of the Chinese People's Political Consultative Conference have come to this inspection, all of which gave high marks. Chinalco Huazhong Copper is hailed as "a window to showcase Huangshi's industrial civilization."
At the beginning of the establishment, a clear low-carbon road was established. In September 2005, China Aluminum Corporation and the Hubei Provincial Government launched a strategic cooperation, and Chinalco Huazhong Copper Company was established. In October 2006, construction began. As the world's top 500, Chinalco has made it clear that it will make Huazhong Copper a “world-class copper processing company†and “China-Alcoa model enterpriseâ€. Promoting circular economy has become a model enterprise for the transformation of resource cities. The first-phase construction scale is 60,000 tons of copper-copper strip and 73,500 tons of billets. The second phase is planned for 100,000 tons of finished products and 200,000 tons of billet production capacity. The annual sales income after reaching the standard for production will be 10 billion yuan. 12 million yuan in productivity. The product market is positioned as "replacement of imports, export-oriented." Revitalize the national high-precision copper strip processing industry and enter the ranks of China's “Three Strongsâ€.
The birth and development of the Huazhong Copper Industry will help promote the "glamorous transformation" of the structural adjustment of the non-ferrous metal industry in Hubei Province and Huangshi City, prolong the important links of the non-ferrous industrial industrial chain in the whole province and even the central and southern regions, and promote the prosperity of the regional economy. Resource-saving and environment-friendly" modern copper processing industry. This “Ning Xiner†has been plunged to the ground by the leaders of the national, provincial, and municipal levels. When the Central Government and the State Council Deputy Prime Minister visited the company, they encouraged employees to practice the scientific development concept and instructed “central enterprises to become representatives of advanced productive forcesâ€; the Central Government, the former Hubei Provincial Party Committee ***** Special instructions were given for the construction of the project; the vice chairman of the National Standing Committee of the Communist Party of China (*****) came to the company to hold a symposium and called for "prominent independent innovation, and good and fast development." Deputy Li Jinhua of the National Committee of the Chinese People's Political Consultative Conference went there. When the company researched, it emphasized that "the road to scientific development should be taken." The leaders of Hubei Province and Huangshi City all supported the green light. Chinalco’s top leaders have also carefully planned and devoted great efforts. The leaders’ cordial concern and strong support have strengthened the company’s determination and confidence to follow the path of “scientific development and low carbon developmentâ€.
Under the guidance of the scientific outlook on development, the leadership of the Central China Copper Industry resolutely abandoned the extensive production model of “high energy consumption, high pollution, and high emissions†and adhered to the concept of “low carbon, energy saving, environmental protection, and lean†to realize sustainable development.
At the beginning of construction, the company plans, designs and builds on the principle of “First Class in China, Leading in the Worldâ€. The goal is to become a demonstration model project for Chinalco and domestic copper processing and build a “landmark†for the development of China's copper processing industry. Business. The program demonstration, process selection, and equipment bidding strictly follow the basic national policy of energy conservation and environmental protection and the requirements of “high starting point, high technology, high quality, high efficiency, and high environmental protection standardsâ€. Such as oxygen-free copper furnace, lead frame furnace, four-roll two-stand cold rolling mill, six-roll finishing mill and other equipment, are the only domestic introduction, equipment reached the international advanced level, with high efficiency, energy saving, environmental protection and superior performance. Especially the second rack cold rolling mill is the second in the world and the first in Asia. The hot rolling mill uses the products designed and manufactured by domestic color technology, which has superior performance and significantly reduces the number of rolling passes compared to traditional rolling mills. Processes and processing equipment that do not meet the requirements of environmental protection, energy saving and emission reduction are discarded in planning and tendering. This fundamentally guarantees that the company will take the path of low-carbon scientific development.
Tens of millions of dollars to promote EHS construction EHS is the abbreviation of Environment, Health Health and Safety Safety. The EHS management system is the integration of the two systems of Environmental Management System (EMS) and Occupational Health and Safety Management System (OHSMS). In August 2008, Chinalco Huazhong Copper achieved the completion of the main production line 14 months in advance, and it officially went into production in January 2010. The company invested 13.2 million yuan for environmental protection, labor safety and industrial hygiene. A small amount of "three wastes" and industrial noise generated in production are treated to ensure a high quality production environment. The smelting furnace and the foundry set up a sealed fume hood. The soot dust passes through 4 baghouse dust collectors, and the dust collection rate reaches 99.8%. The step furnace and the annealing furnace are heated by natural gas, and basically no fumes are discharged. The strip is before the air-cushion annealing furnace. Must be caustic-washed, must be pickled after annealing to produce a small amount of alkali mist and acid mist, the company has set up 7 sets (sets) of purifiers to achieve harmless emission standards; solid slag, corners or surplus materials, or for sale, or Return to remelting, "eat dry squeezed out" to make the best use of it; for the reuse of production water, the recycling rate is 98.1%, where the turbidity circulation system is equipped with oil skimmer, the treated water is still reused, and the surface treatment machine The heavy metal-containing acidic wastewater produced by the air-cushion furnace cleaning is sent to the wastewater treatment station for treatment by flocculation, sedimentation, filtration, sludge concentration, etc. The sediment is sent to a qualified unit for further processing; the hot rolling and roll grinder production is performed with emulsion lubrication. There will be a small amount of waste emulsion produced, through demulsification, air flotation, filtration and biochemical treatment, so that it can be discharged without harm; it also adopts methods such as noise elimination, shock absorption, and sound insulation for industrial noise control. For the instantaneous noise generated by the shearing and milling machines, basic vibration reduction, fan, air compressor silencer, and air-pressure station four-walled viscous sound-absorbing materials are all noise-insulated so that the noise at the plant boundary meets the second-class standard.
The company vigorously built an ecological civilization, strictly protected the mountains and water in the plant area, and adopted the method of planting trees and adopting by employees, and built the “business forestâ€. Now it is luxuriant. The plant is surrounded by hedgerows with a green area of ​​71,597 square meters, and the plant greening rate reaches 34.06%. In the hills and forests of the plant area, the flock of birds fluttered and raced, the hare came and went, and many countries such as the Python were found to protect animals; the staff dormitory area was built on a hill, there was an artificial lake, and the fish in the lake moved. Herons and geese fly to play; the company's small hotel around the villa, there are many unique shapes of the attractions, comparable to the resort area. The company also carried out the activities of creating standard demonstration machines, 6S management, and industrial hygiene standards. The strip plant was clean and dust-free.
How can a “save†word win? Chinalco Huazhong Copper Company recognizes that low-carbon economy is to save energy as much as possible, commit to improving energy efficiency and reduce carbon emissions; at the same time, it researches and develops and uses clean energy to provide services to the society.
The company insists on energy conservation, saves "electricity, water, wind, and gas"; closely tracks industry trends and develops solar photovoltaic device components.
The company has set up an energy office and is equipped with competent cadres; all departments and machines have established part-time energy workers. They are like the "sentinel" of the energy front. They are on the production line day and night to check and block "running, running, dripping, and leaking" at any time. According to the actual production, they have captured one barrier to high energy consumption.
Saving electricity. In order to adjust the power factor of the entire company, and make good use of Huangshi Power's policy of “reasonably increasing the power rate to rewardâ€, rationally operate the reactive power compensation equipment through sub-range adjustment, load adjustment, etc., and appropriately increase the compensation capacity, so that the company The monthly electricity rate has remained above 95, and the annual award has reached 200,000 yuan. Chinalco Huazhong Copper Industry Co., Ltd. implements “centralized production and avoidance of peaks and uses electricity from the valley†to concentrate the production tasks of large-capacity generating units and arrange them to operate at night, adopting valley production as much as possible, avoiding peaks and monthly average electricity prices. From 0.554 yuan / kwh to 0.523 yuan / kwh, the annual savings of 500,000 yuan in electricity. At the same time, the elimination of "long lights", air conditioning in summer and winter to strictly follow the energy-saving regulations, strict implementation of conservation.
Water saving. Recycled water is an important energy medium. According to the operating conditions of the pumping station's cloud ring and net ring system, the diameter of the pump impeller is reduced by 13 to 20 mm, the characteristic curve of the water pump is changed, the water pressure is increased, and the water pump operates in the high efficiency area to achieve the best working conditions. Under the premise of satisfying the production, the waste of water is avoided, and the original unit consumption of water and electricity per ton is reduced from 0.47 kWh to 0.39 kWh, and the monthly electricity consumption is saved by 50,000 yuan.
The festival is a solar term. In order to solve the technical problems of excessive energy consumption and constant pressure in the air compressor station of the company, the technology of centralized control was changed, the products of American companies were selected, and the frequent unloading and use of air compressors were changed through the constant pressure control technology of the main pipe and the parallel operation of pipelines. In the case of unstable pressure of gas equipment, the original four-station air compressors used "three spare ones," and now "use two spare twos" to achieve energy-saving goals. The company's bell annealing furnace uses high-purity hydrogen gas. The original flow rate is 40 cubic meters per hour. After repeated research, it only uses 24 cubic meters per hour, and the amount of use has been greatly reduced, reducing the unit consumption of ton of copper by 35 yuan, and reducing costs throughout the year. 300,000 yuan.
Advancing to the solar photovoltaic industry The main products of Chinalco Huazhong Copper Company are high-end copper strips for power and information electronics. With the advent of a low-carbon era, the demand for energy-saving and emission-reducing products is rising day by day. Solar photovoltaic power generation devices are also in hot demand and the market situation is improving. The company is keen to capture this business opportunity and set up a technical team to start research and development of photovoltaic components, solar tin plating busbars and flexible copper strips.
The company selected high-purity copper with a copper content of up to 99.99%, was cast into an oxygen-free copper substrate using imported equipment, and was carefully rolled into copper strips with high conductivity. After repeated trials, it overcomes technical difficulties such as strip annealing and develops flexible copper strips to ensure that crystalline silicon is not broken during laying.
