High-purity magnesia protective coating

The refractory magnesia manufacturer has a great influence on the furnace type of the heating furnace. The technological progress of the refractory high-purity magnesia and the performance and quality of the refractory material not only affect the furnace structure of the heating furnace, but also affect the operation status of the heating furnace. Maintenance times and service life. Zhisheng Weihua's high-temperature coating engineer pointed out that the refractory materials used in heating furnaces in my country include ordinary clay bricks, high-alumina bricks, ramming materials, plastics, ordinary castables and high-performance castings, high temperature resistant thermal insulation coatings, refractory cement, lightweight thermal insulation Bricks, heavy thermal insulation bricks, thermal insulation felt, aluminum silicate wool and other kiln refractory materials, these materials have high temperature resistance, but they are not easy to transform after high temperature oxidation and friction loss.

High purity magnesia

Due to the influence of fused magnesia in the international market, the annual export volume of magnesite varies greatly. Import and export statistics of magnesite related products.

It is made by flotation and purification of natural super magnesite ore through light burning, fine grinding, ball pressing, and ultra-high temperature oil shaft kiln calcination. It is a high-quality raw material for brick making and indefinite refractories. It is produced from light-burned magnesia with a MgO content of 97% by means of briquetting and high-temperature shaft kiln calcination. The product has good sintering degree and dense crystallization. It is a high-quality raw material for the production of mid-grade magnesia refractory products. Those containing more impurities are used for laying steelmaking furnace bottoms, etc.
