Refractories Co., Ltd., Zhengzhou City shangzhuang learned neutral alumina refractories, chromium oxide, silicon carbide or carbon as a main ingredient. Neutral refractory main products are: corundum bricks, high alumina bricks, silicon Mo brick, mullite brick, aluminum chrome brick, aluminum carbon brick, graphite or carbon bricks. High aluminum products in the main phase is mullite and corundum, alumina content increases with increasing alumina content and refractories, containing more than 95% of alumina corundum products is a wider use of high quality refractory materials. Chromium oxide as the main component of the corrosion resistance of chromium slag brick good refractories wholesale, but poor thermal shock resistance, poor load softening of the alkali erosion, it can not be applied to the conditions of use of the key parts of complex silicon Mo is the use of bauxite and silicon carbide brick two materials as the main raw material, mainly used in cement kiln transition zone. Refractories Co., Ltd., Zhengzhou City shangzhuang understand the full range of refractories refractory resources Which is good, but a variety of refractory reserves uneven. The accuracy of the shape and size for the correctness of the furnace masonry tight body has a direct impact on refractories manufacturers, and masonry body tightness largely determines the lining of life. Zhuanfeng masonry body in the weakest and most fragile part, compared with brick, brick joint density and strength is much smaller, so it is more easily dissolved in the slag, thus weakening the entire lining of the anti- slag resistance and thermal shock resistance. Refractories manufacturers, shangzhuang Refractories (certified), Hainan refractories by shangzhuang Refractories Co., Ltd., Zhengzhou City. Zhengzhou City shangzhuang Refractories Co. (www.yntjj.com.cn) (www.yntjj.com.cn) is Zhengzhou, charge, flux leader, over the years, the company is implementing the scientific management, innovation and development, honesty and trustworthiness guidelines, and satisfy customer needs. In shangzhuang refractory leadership with the staff warmly welcome all inquiries negotiations to create shangzhuang Refractories a better future.
