Introduction：
High temperature castable is a refractory material used to protect and line industrial equipment at extremely high temperatures. High temperature resistant castables can maintain stable physical and chemical properties in a continuous high temperature environment without obvious softening, deformation or shedding.
High temperature resistant castables can resist various aggressive media, such as molten metal, acid and alkali solutions and gases, etc., and protect equipment from corrosion under high temperature conditions.
The formulation and composition of high temperature castables will vary according to specific application requirements. Common materials include high alumina aggregate, vermiculite, yttrium oxide, magnesium oxide, etc., and some special additives may be added to enhance its heat resistance and corrosion resistance.
High-temperature resistant castables are widely used in high-temperature equipment in metallurgy, glass, ceramics, petroleum and other industries, such as blast furnaces, electric arc furnaces, converters, glass kilns, etc. Selecting a suitable high temperature resistant castable requires consideration of factors such as specific process conditions, temperature range, medium composition and use environment to ensure that suitable refractory materials are selected to provide the best durability and protection effect.
