The alkali vapor corrosion of refractory materials is mainly related to the pore structure and chemical composition of the material. The pore structure mainly affects the penetration process of alkali vapor, while the chemical composition affects the chemical reaction process in the erosion process. Therefore, the method to improve the resistance of refractory materials to … Read more
The basic material composition of ordinary refractory ramming materials is basically similar to refractory castables and plastics, and it is also composed of refractory aggregates, powders, binders, and additives in proportion. The difference between them is that the amount of powder in the ramming material is more, and the amount of binder is less. Soft … Read more
