Shangzhuang Refractories Co., Ltd., Zhengzhou City, to understand the future of high-purity refractory materials will be based, and synthetic natural selection and use. Development and utilization of the "three stone" raw material, namely andalusite, sillimanite, kyanite materials, can improve the microstructure and thermal properties LAS refractories. As the "three stone" at high temperatures into the lower phase mullite and mullite expansion coefficient is small, will help improve the material's thermal shock resistance. Add in the material can andalusite with countless subtle diffusion thermal stress becomes void formation, making the stress to be released within the refractory, thereby improving the thermal shock resistance. The sillimanite completely mullitization high temperature refractory material wholesale, will help improve high-temperature creep resistance. Where to buy in addition refractory volume expansion effect due mullitization accompanied produce high temperature creep also beneficial. Shangzhuang Refractories Co., Ltd., Zhengzhou City, the development of high-quality synthetic refractory raw materials found, the amount of developed countries in the use of natural raw materials decreased, while the amount of high-purity synthetic raw materials is increasing, the reason is the extensive use of synthetic materials for monolithic refractories proportion increase, and the extensive use of natural materials clay brick, high alumina brick, zircon brick production is declining. 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 refractories lowest content of corundum with increasing alumina content and higher alumina containing more than 95% of the products are of high quality refractory corundum a wider use of materials. Chromium oxide as the main component of chromium slag bricks for good corrosion resistance, thermal shock resistance but poor load softening of the alkali refractory erosion poor, it can not be applied to the conditions of use of the key parts of the complex, silicon MO Brick is the use of two materials, bauxite and silicon carbide as the main raw material, mainly used in cement kiln transition zone.
