High Alumina Refractory Castable Introduction
High Alumina Castable is a kind of refractory castable which uses high alumina raw material as aggregates and the powder and then be added with binding agent. High aluminum refractory castable has high mechanical strength, good thermal shock resistance, good corrosion resistance. It's mainly used for furnace lining of boiler, blast furnace hot blast stove, heating furnace, ceramic kiln and various industrial furnaces.
High Alumina Castable Features
1.Has a certain degree of corrosion resistance;
2.High refractory temperature and high load softening temperature;
3.High compressive strength and excellent thermal shock resistance;
4.High density, low porosity.
5.Good resistance to flake performance.
Refractory Castables Classification
1. According To Chemical Properties, It Is Divided Into Acid-Resistant Castables, Neutral Castables And Alkali-Resistant Castables.
2. According To Density, It Can Be Divided Into Light Castable And Heavy Castable.
3. According To Refractory Materials, It Is Mainly Divided Into Different Refractory Materials Such As Clay Castables, High Alumina Castables, Siliceous Castables, Mullite Castables, Corundum Castables, Magnesia Castables, And Silicon Carbide Castables.
4. According To Their Characteristics, They Are Divided Into: High-Strength Wear-Resistant Castables, High-Temperature Wear-Resistant Castables, Low-Cement Castables, Steel Fiber Castables, Acid-Resistant And Heat-Resistant Castables, Slag-Resistant And Wear-Resistant Castables, Heat-Resistant Castables Steel Fiber Reinforced Refractory Castables And Other Refractory Castables With Unique Properties.
5. According To The Use, It Can Be Divided Into Various Industrial Kiln Castables Such As Steel Rolling Heating Furnace Castables, Blast Furnace Runner Castables, Metal Mixer Castables, Ladle Castables, Boiler Special Castables, Furnace Door Castables, Cement Kiln Castables, Etc. .
Different Size Classifications, Types Of Refractory Castables And Applicable Industrial Furnace Environments Are Also Different, So Appropriate Refractory Castables Should Be Selected.
