1. Product Introduction
Refractory bricks are refractory products made by mixing soft clay and hard clay clinker according to a certain ratio, forming at high pressure and sintering at high temperature. They are mainly used to build the lining of high-temperature industrial furnaces. Refractory bricks can be divided into standard type, ordinary special type and special type according to their shapes. According to the material, it can be divided into clay brick, high alumina brick, silica brick, magnesia brick, carbon brick, corundum brick, etc.
2. product attribute
