Manufacture SK32 SK34 Low Porosity Refractory Fire Clay Brick For Sale

Fire clay bricks are the most widely used refractories made from clay minerals. It can be easily located out in the nature and contains suitable content ratio of silica,cyanite and alumina. Some people call them fireplace bricks as they are used for building cooking chamber in wood fired ovens, for creating fireplaces, all sorts of fire boxes and wood heaters’ lining, linings in a small or the hugest industrial furnaces, you name it. Fire clay bricks have low porosity and are durable for various re-heating process.

Low porosity bricks are made from low mullite stones, the main mineral composition of the low mullite stones are pressed and sintered mullite phases. The bricks have very good physical and chemical properties in high temperature conditions.

Applications

Fire Clay Brick Applications

Fire Clay bricks are mainly used in the low temperature parts of blast furnaces, waste incinerators and glass melting furnaces. Due to the scale-up of a variety of industrial furnaces and severity of operating conditions, super dense fire clay bricks that made of more refined chamotte being calcinated at high temperature are applied more than before. It's popular in the following furnaces:
1. Blast furnaces and hot blast furnaces
2. Waste incinerators
3. Glass melting furnaces
4.Metallurgical furnaces
