Breathable bricks and seat bricks for ladle

Breathable bricks and seat bricks for ladle

The air-permeable brick for ladle developed by our company is made of plate-shaped corundum, spinel, chromium oxide and other materials, which are formed, fired, and assembled. It is characterized by high strength, erosion resistance, erosion resistance, and high air permeability. Suitable for all kinds of ladle use. In particular, the newly developed ventilated bricks containing nitride materials have good corrosion resistance, are not easy to penetrate steel, and have a high blow-through rate. They are the most popular ventilated brick products for customers.
