Product Introduction
The forming process of the steel casting bricks is complicated. It requires smooth inner wall, regular shape and tight joints. The sintering process requires reasonable temperature rise and fall. It is a refractory product with a rigorous manufacturing process.
Product Advantage
- It has the characteristics of high refractoriness, good resistance to cracking and strong resistance to erosion
- Can remain stable in high temperature environment, not easy to deform or peel off
- It has good effect especially when used at high temperature.
Application Field
Steel casting bricks are generally rectangular hollow clay bricks with various specifications, which are widely used in the flat plate casting and bottom casting method of various types of steel.
