Gongyi Weida Co., Ltd. was founded in 1999. It is the spirit of the enterprise to be honest and healthy, and to achieve the best. It is Weida's business policy to attach importance to quality, rather than damage itself, keep its reputation and not let users suffer losses. Our company from the selection of raw materials to the production of finished products.About Us
Weida company collects the technical elites of refractory industry, relying on the company's R & D department, and cooperates with Wuhan University of science and technology, Luoyang Refractory Research Institute and other scientific research institutions to develop an ideal product. The company's existing modern equipment, the implementation of large-scale production, annual production capacity of 50000 tons, products sold to Japan, South Korea, Vietnam, Laos and other countries.
The main process flow of sintering refining slag production is proportioning, mixing granulation, sintering, cooling classification. On this basis, in order to achieve the stability of raw material conditions and reduce the standard deviation of silicon dioxide and iron grade in raw materials, a raw material mixing process (i.e. pre proportioning) is added before proportioning, and the sintering process can increase the bedding process, adopt hot air sintering, reduce the standard deviation of silicon dioxide and iron grade in raw materials In order to improve the reaction heat effect in the sintering process, we can improve the physical and chemical properties of sinter by improving the phase transformation in the reaction process. We can reasonably select different sizes of sieves in the cooling classification. First, we can classify part of the bedding material, and second, we can create good conditions for the next process.
