Product Details
Product Introduction
High-strength mullite castable is a high-performance refractory castable made of mullite aggregate as the main raw material, supplemented by micro powder and a variety of additives. This product has the characteristics of excellent thermal shock stability, dense structure, low creep rate, small thermal expansion coefficient and strong resistance to chemical erosion, which can effectively extend the service life of the kiln lining. Its curing, demoulding and baking time are short and it is not easy to burst. It is suitable for key parts such as pre-decomposition kiln, front kiln mouth, coal injection pipe, and low wall of cooler of small and medium-sized cement kilns. The product is divided into three grades according to physical and chemical indicators: JC-80MC, JC-70MC, and JC-65MC, which have different refractory and mechanical strength indicators to meet various specific use needs. High-strength mullite castable is easy to operate and has stable performance. It is an ideal choice for high-temperature industrial fields, especially cement, metallurgy, chemical industry and other industries to ensure production efficiency and equipment life.
