High Alumina Brick for Steel Cement and Lime Industries Manufactured by Henan Hongtai

High Alumina brick with aluminum oxide (Al2O3) content higher than 48%.

A neutral refractory with an alumina content of more than 48%. It is formed and calcined from bauxite or other raw materials with high alumina content. High thermal stability, refractoriness above 1770℃. It has good slag resistance and is used to build the lining of steel-making electric furnaces, glass melting furnaces, cement rotary furnaces, etc.

The international standard high alumina brick code is the model beginning with SK. Among them, the aluminum content of SK-34 corresponds to the domestic content of 48, the SK-36 corresponds to the domestic content of 55, and the content of SK-38 is 75. High alumina bricks are differentiated according to their Al2O3 content. Currently, 48%, 55%, 60%, 65%, 73%, 75%, 80%, etc. are often used. 

1.Made by bauxite clinker and binder through Crushing,Mixing,Shaping,Drying and high temperature Sintering.
2.Al2O3 content is 48%-80%,main mineral components are corundum and mullite phases.
3.Refractoriness is above 1770°C,refractoriness under load is 1420-1550°C.
4.Working temperature:1350°C -1650°C.
