The role of steel fiber in ceramic fiber cotton
I believe everyone is familiar with ceramic fiber cotton, but these contents are not enough for customers who want to know more about this product. Today, Xiaobian will share with you the knowledge about ceramic fiber cotton adding steel fiber, hoping to attract everyone's attention and let everyone have a deep understanding of ceramic fiber cotton.
Everyone can know fairly well when buying and using ceramic fiber cotton, and they are in no hurry. I hope it will inspire and help everyone. The main functions of adding steel fiber to ceramic fiber cotton are: strengthening toughness, improving stress-strain resistance and improving mechanical impact resistance; Improve thermal shock resistance, improve cracking and peeling resistance; Restrain linear shrinkage after curing, drying and heat treatment. The addition of steel fiber is generally 0.6-2.5% (volume ratio).
However, the amount of steel fiber should not be too large. Too much steel fiber will make the high-temperature physical and chemical properties of refractory castable worse, such as steel fiber will make the residual linear expansion of castable after high-temperature firing. At the same time, the content of iron oxide in castable is increased and its corrosion resistance is reduced. Adding too much steel fiber will make the workability of castable worse.
From the content described in this paper, we know the specific meaning of steel fiber in ceramic fiber cotton. I hope the content described in this paper will be helpful to everyone, and we must pay attention to this requirement in future operations.
