Product description
Lightweight castable refractory are mainly made of lightweight refractory aggregates, powders, and binder admixtures.
lightweight castable refractory can be divided into: according to volume density:
Semi-light insulation castable, bulk density is 1.0~1.8g/cm³;
Lightweight refractory castable, bulk density is 0.4~1.0g/cm³;
Ultra-light refractory castable with a bulk density of less than 0.4g/cm³.
The smaller the density, the better the thermal insulation performance, and the higher the price.
Application of insulating lightweight castable refractory
Lightweight castable refractory is easy to be constructed, is the best construction product for the high temperature alkali resistant parts. Good workability, strong cohesion, initial setting time and construction can be a long time, fast strength growth, strong impermeability, no acidification, easy to ensure that the masonry plaster full and dense, can significantly improve the chimney liner air tightness, integrity and anti-corrosion ability. Refractory castable insulation is an ideal cementing material for high chimneys, high temperature flue and duct lining. Insulating castable refractory can also be used in acid tank and other acid resistant parts in petroleum, chemical, nonferrous metallurgy and so on.
Lightweight castable refractory have a wide range of applications.lightweight castable refractory are commonly used as insulation layers in the linings of kilns, thermal equipment, flues and smoke windows in industrial sectors such as metallurgy, machinery, petrochemicals, electric power and building materials.
