Lightweight refractory bricks belong to the category of lightweight insulation refractory materials. The common characteristics of this material are small volume, light weight, and low thermal conductivity. But the strength is low, and high-temperature burns cause significant shrinkage, resulting in good insulation and moisturizing effects. There are multiple classification methods for lightweight refractory bricks: according to the temperature of use. The use temperature of insulation materials is 600~900
There are over 1200 high-temperature insulation materials in the temperature range of 900~1200 degrees. Volume density. CMS is a lightweight refractory brick with a bulk density of 0.4~1.3g/; Ultra lightweight refractory bricks below 0.4g/cm3.
Sort by product shape. A type of lightweight refractory brick, including clay refractory bricks, high alumina insulation refractory bricks, siliceous refractory bricks, lightweight refractory bricks, and some pure oxides, and other types of uncertain lightweight refractory bricks, such as lightweight refractory concrete.
There are four methods for making light refractory bricks: foam method. The mechanical method of adding foaming agents to refractory clay, such as rosin soap, to create bubbles and obtain porous brick products after combustion. Burn up addition method. Also known as combustible materials. At the end of refractory bricks, clay, combustible materials such as carbon and sawdust can be easily consumed, allowing the refractory bricks to have a certain degree of porosity after combustion.
Porous material method. Light firebrick is made of natural diatomite or artificial dry foam, alumina or zirconia hollow ball and other porous materials. Chemical method. In the production process of refractory bricks, a porous refractory brick is obtained through appropriate chemical reactions. Rongsheng refractory materials provide you with high-quality lightweight refractory bricks.
