what is Thin fire brick
Thin fire brick is a high temperature material, mainly used for heat insulation and refractory in high temperature environments such as furnace walls and kilns. It is usually made of refractory raw materials and additives through high temperature sintering. It is thin, usually about 10 mm, and has excellent refractory, thermal stability and thermal conductivity. Thin fire bricks can effectively reduce heat loss and improve energy efficiency. They are widely used in high temperature equipment in metallurgy, keramik, kaca dan industri lainnya. Its light weight and high strength make it more and more valued in modern industry.
Physical and chemical indicators of thin fire brick

How thick do fire bricks need to be?
The thickness of fire bricks usually depends on the specific application and usage environment. Secara umum, the thickness of standard refractory bricks is mostly between 23 mm (about 1 inch) Dan 76 mm (about 3 inches). Here are some uses of different thicknesses:
- 20-25 mm: Suitable for lighter load applications of some high-temperature furnace walls.
- 30-50 mm: Suitable for most high-temperature furnaces and kilns, providing good insulation effect.
- Di atas 50 mm: Suitable for industrial furnaces that withstand high thermal shock and heavy loads, such as smelting furnaces or petrochemical equipment.
Main uses of thin fire brick
- Industrial furnaces: such as iron-making furnaces, steel-making furnaces, coke ovens, dll..
- Heat treatment furnaces: used in the heat treatment process of metals.
- Kiln Linings: including glass melting furnaces, tempat pembakaran semen, dll..
