Description: XS-Z series products are new products developed according to the characteristics of fluids. With the help of its own gravity, the products level without vibration and segregation. They have high temperature resistance, good thermal shock stability, corrosion resistance and erosion resistance. Depending on the model, it can be used for the bottom of the ladle and around the block brick, the furnace cover of the triangular area of the electric furnace top, the burner brick, the ladle, and the permanent lining of the tundish. Products that meet the requirements can be designed according to customer needs.
Recommended Products
At present, the company's core products are ladle-blown argon permeable bricks, among which the company's leading products such as corundum spinel permeable bricks and various high-grade prefabricated parts are well received by users.
