Product Description

High Alumina High-strength Refractory Castable for Ramming
The Description:
High-strength High-alumina Castable is a refractory castable with aluminate cement as the binder, high-aluminum aggregate and micro-powder (such as α-Al2O3 micro-powder, etc.) as the main raw materials. High strength aluminum castable has high compressive strength, folding strength and thermal shock resistance, and can maintain good stability in high temperature environment.

The characteristics of high strength and high aluminum castable are as follows:

1, Excellent high temperature performance: due to the high refractoriness of high aluminum aggregate and high aluminum cement, high strength and high aluminum castable has excellent high temperature performance and can be used in an environment of up to 1000ºC or more.

 

2, High strength: high strength and high aluminum castable has high compressive strength and flexural strength, and can maintain stable structural properties under various complex working conditions.
 

3, Good heat resistance: due to the selection of high strength and high aluminum castable aggregate and powder has a low coefficient of thermal expansion, so that it has a good heat resistance performance, suitable for high temperature equipment.

 

4, Chemical erosion resistance: high strength and high aluminum castable has good acid resistance, alkali resistance, salt resistance and corrosion resistance, suitable for chemical, petroleum and other industries may appear chemical erosion occasions.
The application:
High strength and high aluminum castables are widely used in various industrial furnaces and equipment in metallurgy, petrochemical, building materials, electric power and other industries, such as iron and steel furnaces, petrochemical furnaces, cement kilns, glass furnaces, waste heat power generation equipment, etc. When using high strength and high aluminum castable, the appropriate formula and construction method should be selected according to the specific working conditions and requirements to ensure its performance and service life.
