1, Description of Andalusite Runner Brick : The runner brick is used in the flowing casting process of molten steel and hot metal. The requirements for the product are: high temperature resistance, erosion resistance, rapid cooling and heating resistance, good compactness. Therefore, based on the clay cast steel brick and high aluminum cast steel brick, in recent years, we have developed and produced andalusite high aluminum cast steel brick. Andalusite is added in the form of fine powder, and the amount of addition is generally 15-25% Part, fully improve the structure of the product, improve the product's rapid cooling and heating resistance and high temperature erosion resistance, effectively improve the product's use times. At present, hongzhushi high alumina cast steel brick completely replaces the general clay and high alumina cast steel brick, which is very popular with users, saving production cost, reducing the number of times of soaking molten steel, and increasing economic benefits. The andalusite cast steel brick supplied by our company has been used by domestic users, as well as Korean, Russian, Australian and other users, and has received good use effect and won high praise from users
