Breathable bricks and seat bricks for ladle
The air-permeable bricks for ladle developed by our company are made of plate-shaped corundum, spinel, chromium oxide and other materials, which are formed, fired, and assembled. They are characterized by high strength, erosion resistance, erosion resistance, good air permeability, etc. Features, suitable for all kinds of ladle use. In particular, the developed breathable bricks containing nitride materials have good corrosion resistance, are not easy to penetrate steel, and have a high blow-through rate. They are a new generation of breathable brick products.
