Henan Yuanzheng Metallurgy Technology Co. ，Ltd.

       According to China's metallurgical industry in the production process, there will be a secondary iron resources (such as return fines, dust, dust manganese, zinc dust and other effective resources) generated approximately than 10 million tons per year. Currently, the majority of metallurgical enterprises of dust, mud treatment is scrapyard accumulation, external processing, both on the serious environmental pollution and waste of resources, some of the companies with the sintering, but sintering also occurs when bonded Comparison poor, difficult to mold and other problems, which will increase the production of soot pollution. So how to provide resource utilization, optimize the structure of blast furnace, dust gray molding and solve difficult issues such as the use of the metallurgical industry has become the focus of research.
