Haas taigang section steel slag comprehensive utilization of dry processing line (EPC) project profile Steel slag is one of the main iron and steel industry waste residues, as a worldwide problem, the use of steel slag processing technology is widespread attention at home and abroad. Taigang group and the United States haas company was founded in November 2011, a joint venture, for steel slag utilization, in order to meet the requirements of sustainable development strategy of taigang, the realization of taigang steel slag zero emission and recycling targets. The implementation of the project will not only improve taigang steel production, it will also reduce the emission of harmful gases, also could be used for industrial and agricultural production of associated products, as well as the domestic and even world metallurgy industry to realize efficient use of steel slag and iron and steel enterprises will play a demonstration and leading role transformation development. Haas section steel slag comprehensive utilization project, equipped with the most advanced equipment, adopting the most advanced metallurgical steel slag utilization technology, with a total investment of 1 billion yuan, the construction began on March 27, 2012. The first phase of the main construction of 1 million tons of stainless steel wet tail slag processing 350000 tons, 350000 tons of steel slag embankment materials, stainless steel tailings drying and fertilizer manufacturing, 300000 tons of carbon steel slag crushing and super fine powder and 100000 tons of steel materials five production lines. Haas section steel slag comprehensive utilization project is the world's most advanced technology of steel slag comprehensive utilization of environmental projects and China's first steel slag fertilizer manufacturing project. Mountain ore company and shanxi taigang in January 2012, haas branch technology co., LTD. Signed a comprehensive utilization of steel slag dry processing line (EPC general contracting project, mountain mine company to undertake the project design, equipment manufacture, supply, transportation, installation, civil engineering, testing, debugging, acceptance, training, etc. The whole process of project, value of 33.23 million yuan, the project in shandong province won the 2014 mass synergistic assembly contracting class award. Haas section steel slag comprehensive utilization project issue of all project to produce in the third quarter of 2013, 2013 sales income 470 million yuan, has become the world's largest iron and steel enterprise production, the process complete, the most advanced technology of fertilizer and related metallurgical ancillary products production base, taiyuan steel slag will all efficient recycling and zero emissions, leading Chinese steel slag utilization trend, impact on the metallurgical industry to realize the steel slag recycling demonstration and leading role. EPC project general contracting mode represents the mainstream of modern western project management, engineering management mode and the perfect combination of design, successful application of this model is to shorten the construction period, reduce the model of investment purposes. Therefore, the project USES the EPC general contracting construction model is the trend of The Times, unstoppable. Successful implementation of this project in a bigger impact in the industry, well played for general contracting mode of demonstration to promote and drive the supporting role; Through the implementation of the general contracting project for haas and mountain mine of taiyuan iron and steel company has brought great economic benefits and drive the industry chain of steel, paint, tape, motor, reducer, electrical components and other related enterprises development.
