Self flow refractory castables

Detailed introduction

Self-flowing refractory castable is a high-tech product developed on the basis of solid-state fluid theory, the closest packing principle and the application characteristics of refractories. It is known as "the fourth generation castable" and is a substitute for low cement, ultra-low cement and cement-free castable. The product is characterized by no vibration by its own gravity flow, to achieve densification of the lining, a reasonable solidification time, no segregation, high strength, long life, good thermal shock stability, erosion resistance, time-saving and labor-saving. This product is suitable for heating furnace water cooling tube wrapping and thin wall lining repair. It has been used in Baoding Yaxin, Henan Yaxin, Tangshan Yongjia, Daqiu Zhuangjinchao, Yinfeng and other heating furnaces. The effect is good, and has been praised by customers.
