High alumina bricks are the most commonly used refractory materials, widely used in steelmaking and ironmaking furnace and so on. High alumina bricks for a direct impact on the quality of its many properties, such as high temperature resistance, and so on, our company will introduce factors affecting quality of high alumina bricks, hope can help you through this learning under normal circumstances, according to the content of chemical ingredients in high alumina refractory brick and its role, its primary constituents, impurities and plus ingredients in three categories.
Principal components of high-alumina brick refers to the predominance of, chemical composition on high temperature properties of materials play a decisive role. High alumina bricks for why with excellent resistance to high temperature performance, as well as many refractory materials and each has its own characteristics? Completely or largely based on a refractory material content of chemical ingredients and its role in, always as main constituents, impurities and plus composition three types.
Impurity is separate from the main components in refractories, content minimal resistance to high-temperature properties of high alumina bricks are often hazardous chemicals. Chemicals that are done by entrainment of principal component raw materials.
