Product Desciption

High Alumina Bricks For Uses:

High alumina bricks are aluminate silicate refractory materials contain more than 48% alumina oxide. They belong to neutral refractory materials. The bricks are made from bauxite or other kind of high alumina raw materials by molding and firing. They have a high thermal stability, and can withstand high temperature of more than 1770ºC. The bricks are mainly used as linings to build electric iron furnace, glass kiln or cement rotary kiln.

Features:

1.High refractoriness

2.High refractoriness under load

3.Good slag and chemical erosion resistance

4.Resistance to acid, alkali and spalling

5.Excellent thermal shock resistance

6.High temperature low creep

Applications:

1. Furnaces of metallurgy industry, heat treatment furnace
2. Furnaces of chemical industry and construction industry
3. Furnace of incineration of garbage, recirculating fluidized bed furnace
4. Standard sizing: 230 x 114 x 65 mm others up to the client
