Refractories Co., Ltd., Zhengzhou City shangzhuang understand the development of production of refractories and steel industry and technological progress are interdependent and mutually reinforcing. Modern history shows that the development of metallurgical production, each of the major iron and steel smelting furnace refractories casting steelmaking process changes, are accompanied with refractory replacement. Shangzhuang Refractories Co., Ltd., Zhengzhou City, found that with the strengthening of blast furnace, coke oven, converter, electric furnace smelting large and hot metal pretreatment composite top and bottom blowing converter and continuous casting widespread adoption of new technologies such as steel casting furnace refractories, refractory materials has become improve smelting equipment life, improve product quality, expanding product variety, improve the economic efficiency of one of the key steel casting furnace refractories, which also put the refractory industry to a new stage . Some refractories will develop traditional "Zhulu material" to "functional refractories" Some refractories has become an integral part of the smelting process equipment, for example, invasive outlet, long nozzle or sizing of the casting nozzle brick ; ceramics and spray gun of metallurgy and so on. Shangzhuang Refractories Co., Ltd., Zhengzhou City, Xiao Bian found the world is composed of matter. There are thousands of casting furnace steelmaking material refractories, ever-changing performance. However, not all substances can be used as refractory materials. As the refractory properties should have some use, should also be made with the condition. So, how to use a variety of materials made of a variety of refractories, where the edge is very demanding, this knowledge is a science.
