What is soft fire Brick? According to the specific gravity of refractory products, it is divided into heavy and light. For example, 0.4-1.0 bulk density is light brick; 1.2-1.8 is medium brick, 2.0-3.9 specific gravity is heavy brick, and light refractory brick is light. The general term for thermal insulation products, which can be applied to light bricks of various materials.
What is soft fire Brick?
It can be understood that the porosity in the product is high, and the body contains a large number of pores (including closed pores and open pores). Because the product contains a large number of pores, it is a refractory product with light weight and good thermal insulation function.
What are the more common soft fire bricks?
According to the material of light refractory products, there are clay (clay insulation brick), high alumina (high alumina poly light insulation brick), silica (light silica brick), mullite (mullite poly light insulation brick) , Corundum mullite (light corundum mullite brick), alumina (alumina hollow ball brick) and so on.
Features
soft fire brick is a refractory product with good thermal insulation function. Because the product contains a large number of pores, it has low compressive strength, poor slag resistance, and poor thermal shock resistance. Ordinary products cannot directly contact the flame. soft fire high-alumina bricks It can touch the flame, but the contact surface should not exceed 1400 degrees. Mullite insulation brick, light corundum mullite brick, and alumina hollow ball brick can all touch the flame according to the product specifications.
Product Usage
soft fire bricks are refractory products for high-temperature industrial furnaces and heat supply equipment for thermal insulation layers. They are mainly used for thermal insulation, which can effectively reduce thermal energy loss, save energy consumption, and reduce the load-bearing of the main body.
