China Clay Fire Block Refractory, Find details about China Fire Clay Brick, Refractory from Clay Fire Block Refractory
Description
Clay Fire Blocks 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. Clay Fire Blocks have low porosity and are durable for various re-heating process.
Specifications
High resistance to thermal shock, abrasion, chemical attack to provide long service life
High dense structure;
Low permanent linear change on reheating
Easy operation and installation
Broad usage or applications and low price
Applications
Clay Fire Blocks 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 Clay Fire Blocks 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
