The main functions of adding steel fiber into ceramic fiber cotton are: enhancing toughness, improving stress-strain resistance and mechanical impact resistance; Improve thermal shock resistance, cracking and spalling resistance; Restrain linear shrinkage after curing, drying and heat treatment. The addition amount of steel fiber is generally 0.6-2.5% (volume ratio).
However, the amount of steel fiber should not be too large. Excessive amount of steel fiber will deteriorate the high-temperature physicochemical properties of refractory castable. For example, steel fiber will increase the residual linear expansion of castable after high-temperature burning. At the same time, the content of iron oxide in castable increases and its corrosion resistance decreases. Adding too much steel fiber will also make the workability of castable worse.
Through the content explained in the article, you can generally understand the specific significance of not adding excessive steel fiber to ceramic fiber cotton. I hope the content explained in the article will be helpful to you. In future operation and use, you should pay more attention to this requirement.
