Abstract

[0002] Refractory bricks, also known as fire bricks, are refractory materials made by firing refractory clay or other refractory raw materials. They are light yellow or brown in color and are mainly used for building smelting furnaces. They are refractory materials with certain shapes and sizes. According to the preparation process, they can be divided into fired bricks, unfired bricks, fused bricks (fused cast bricks), and refractory insulating bricks. According to the shape and size, they can be divided into standard bricks, ordinary bricks, special bricks, etc.
