遼甯red bric

Red pillar stone brick is made of corundum, andalusite and other main raw materials, and its particle size is strictly controlled. A new process is applied, which adopts multi-stage batching, matrix homogenization, and better calcination temperature. The red pillar stone brick with excellent performance can fully meet the needs of different parts of blast furnace and hot blast furnace and different working environments.

Andalusite is mainly used in industry for its high temperature resistance. When andalusite was heated to 1350 ℃ under normal pressure, it began to transform into needle like mullite. Mullite crystal is the only stable form of aluminosilicate under high temperature.
