Product Details

Corundum Brick

Product Description

Features

1.High density

2.Strong corrosion resistance

3.Good slag resistance

4.Low permannent liner change on reheating

Application

High purity corundum brick is usually used in petrochemical industry. In addition, it is also adopted as high temperature interlayer between AZS ans basic bricks in order to avoid the reaction of interface at high temperature.
