Description
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, ceramics, glass and other industries. Its light weight and high strength make it more and more valued in modern industry.
Physical and chemical indicators of thin fire brick
| Indicator name | definition | unit | General Requirements |
|---|---|---|---|
| Loss on ignition | The percentage of refractory weight loss at a certain temperature | % | Should not exceed 5% |
| Bulk density | The ratio of the volume to weight of a refractory material at a certain temperature | g/cm³ | 2.0-2.7 g/cm³ |
| Apparent porosity | Visible porosity on the inner surface of refractory materials | % | Below 24% |
| Flexural strength | The resistance of refractory materials to fracture under a certain load | Mpa | 10-40 Mpa |
| Linear expansion coefficient | The rate of change of the linear expansion coefficient of refractory materials during thermal expansion and contraction | 10^-6/℃ | 4.0×10^-6/℃ or less |

How thick do fire bricks need to be?
The thickness of fire bricks usually depends on the specific application and usage environment. Generally speaking, the thickness of standard refractory bricks is mostly between 23 mm (about 1 inch) and 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.
- Above 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, etc.
- Heat treatment furnaces: used in the heat treatment process of metals.
- Kiln linings: including glass melting furnaces, cement kilns, etc.
