Self-flow refractory castable
Classification:
Product Introduction
Through the reasonable selection of raw materials and particle size distribution, and the introduction of ultra-fine powder and high-efficiency dispersant, the Self-flow refractory castable for heating furnace is developed. The product is easy to construct, self-leveling to achieve densification, with good volume stability, good thermal shock stability characteristics. It is suitable for the parts with complex shape and narrow space.
