Insulating fire brick is a kind of insulating products with a regular shape. It belongs to light insulation refractory material. The common characteristics of this kind of material are small volume density, light bulk density, low thermal conductivity. But the intensity is low, high temperature reburning shrinkage is larger, heat insulation, good moisturizing effect. Refractory brick, also known as firebrick, is made of heat-resistant ceramic materials, similar in shape to ordinary building bricks, so they are often used in building kilns and a variety of thermal equipment. Firebrick won't have chemical change below high temperature on one hand, also be the material with poorer heat conduction commonly. Let's talk about the difference between insulating fire brick and refractory brick.
Here is the content list:
What are insulating fire bricks and refractory bricks?
The key effect of insulating fire brick is used for heat insulation, reduces the outflow of heat. Insulating fire brick is not easy to direct contact with fire, and refractory brick is generally direct contact with fire.
Insulating fire brick porosity is high, volume is close small, thermal conductivity is low, but heat insulation performance is good, a few high-grade insulating fire bricks, also can be used as working layer directly.
