High Alumina Bricks Uses

According to the wikipedia description, high alumina bricks are the high temp refractory alumina bricks, which are widely used in many industries.

Firstly, the refractory bricks generally be used in the industries of steel & iron, chemical engineering and cement.

Then, they are used as refractory lining in all kinds of thermal kilns.

What’s more, these fire bricks are used in blast furnace, hot blast stove, EAF, steel ladle, molten steel ladle, cement kiln, glass furnace, reverberatory furnace, rotary kiln and so on.

Last but not least, the alumina bricks can be used as a kind of furnace bricks, such as regenerative checker bricks in open hearth furnace, chock plug and nozzle brick in pouring system.

High Alumina Brick Manufacturing Process

High alumina bricks manufacturing process is similar to the fireclay bricks’. But for the differences, the high alumina bricks use higher proportion of clinker that reach up 90~95%. Select out and sieve all the iron slag before crushing and firing the clinker in the high temperature that reach up 1500~1600 degree.

RS Group Manufacturer, as on of the Chinese High Alumina Refractory Supplier, proves that in order to improve the high alumina brick products’ quality, it is necessary to sieve and store strictly the high alumina clinker in grades and then fine grind the bauxite clinker and binding clay together.
