Product Description

Silica Checker Refractory Bricks for Hot Blast Furnace
The Description:
Silica lattice brick is a refractory product with silica as the main component and its content is more than 93%. It is made of quartzite as raw material, adding mineralizing agent and bonding agent, and is mixed and made at high temperature. At present, lattice bricks are mainly used in blast furnace hot blast furnace and flame furnace. The lattice bricks are mainly used in the regenerator of hot blast stove. The lattice bricks with lattice holes are arranged in an orderly manner. The upper and lower holes of the lattice bricks can allow gas to pass through.
