Lightweight castable is a kind of castable mixture which is made up of lightweight refractory aggregate, powder, binder and admixture. Because of its small volume and low thermal conductivity, lightweight castable can also be called thermal insulation refractory castable.

Generally speaking, light refractory castables can be divided into:

Lightweight castable

The volume density of semi light refractory castable is 1.0-1.8g/cm3

The volume density of light refractory castable is 0.4-1.0g/cm3

Super light refractory castable with bulk density less than 0.4g/cm3

Light castable is divided into:

Low temperature light refractory castable, service temperature of 600-900 ℃

Medium temperature light refractory castable, service temperature 900-1200 ℃

High temperature light refractory castable, service temperature is more than 1200 ℃

In general, different types of lightweight castables can be selected according to different temperature and volume density.

The above is the description of how to distinguish the type of light castable from the self-supporting refractory of the castable manufacturer. The company is located in Xinmi, specializing in the production of non stick aluminum castable, low cement castable, high aluminum castable, steel fiber castable, light castable, fire-resistant castable, wear-resistant castable, etc. The self-supporting refractory has successively developed aluminum silicate series, siliceous series, alkaline series, light heat insulation brick series and other shaped products for coking, building materials, steel, nonferrous, electric power and other industries, as well as casting materials, self flowing materials, plastic and other non shaped materials of different materials, and has become the designated supporting enterprise of refractory recommended by the above design and scientific research departments.
