Product Introduction
This product is an innovative high-tech product developed through our company's independent R&D efforts. In 2009, it obtained a national invention patent (patent number: ZL2007 1 0189926. X), won the first prize of Zhengzhou Science and Technology Progress Award in 2010, and was awarded a famous brand product in Henan Province in 2011. The product is mainly made of composite fused magnesia chromium spinel and fused magnesia sand, with special nano materials added. It is formed by high-pressure molding and ultra-high temperature sintering. It not only has the characteristics of high temperature strength, erosion resistance, but also has properties such as heat resistance, shock resistance, and peeling resistance.
