refractory withstand high temperature insulating light weight high alumina fire brick are produced with selected bauxite chamotte by advanced process and strict quality control. The main mineral components are corundum and mullite phases. Its features are excellent high temperature mechanics and chemical corrosion resistance.

 

refractory withstand high temperature insulating light weight high alumina fire brick of over SK35 contain over 45% Alumina and are made from raw materials of unusually high degree of purity of Bauxite and refractory clay. For serve under severe conditions,JUCOS Alumina bricks have excellent mechanical strength, good resistance to thermal spalling, and are highly resistant to chemical attack by vilatile alkaies and some slag. We manufacture and design alumina bricks to meet the requirements of a great variety of service conditions thorough quality control.

 

refractory withstand high temperature insulating light weight high alumina fire brick refractory brick the main chemical components: Al2O3 content is 30%-48%, SiO2 content is 50%-65%, and a small number of alkali metals, alkaline earth metal oxides, etc. Mineral composition is usually mullite, quartz and glass phase. Its refractoriness is 1580-1750℃, refractoriness under load is 1250-1450 ℃, line expansion coefficients is low, with good thermal shock resistance and strong ability to resist erosion acid slag.

 

 

Production process:


The production methods of refractory withstand high temperature insulating light weight high alumina fire brick and clay bricks are basically the same.

 

Only some process parameters are different. There are also processes such as crushing → mixing → molding → drying → firing → inspection → packaging.

 

 

Feature
