Lightweight refractory brick means that the refractory brick density less than 1.3x103kg/m3, owing to the characteristics of small density, high porosity, small thermal conductivity, good heat insulation performance and certain compression strength, it is widely applied to heat treat facility. So what should be attention to when using the material. This article will introduce for you in detail.

1. Lightweight refractory bricks have the properties of large porosity and loose structure, so it can’t used in the parts where directly contact with slag and liquid metal.
2. Low mechanical strength, can’t used in load-bearing structure.
3. Poor wear-resistance property, not suitable for the parts where contact with furnace burden and the parts with serious abrasion.

Lightweight refractory bricks have its particularity  and high utilization rate of the products, so we must remember the application notices in the process of using.
