refractory lightweight high alumina thermal insulating fire brick
Product Description
Refractory lightweight high alumina thermal insulating fire brick is made out of a naturally-occurring material known as bauxite. This material includes aluminum hydroxide, which is what gives the bricks such great warmth resistance. The bricks also include kaolinitic clays, which are roasted to create an unique combination including mullite and also synthetic alumina. This is where the name “high alumina” stems from.
Features
1.High-temperature endurable .
2.Good thermal shock resistance .
3.High cold crushing strength.
4.Good resistance to abrasion and corrosion.
5.Good thermal spalling resistance.
6.High mechanical strength.
7.Good volume stability at high temperature.
Application
1.General use in heat containment unit form temperature 1500-2000°C.
2.Resistant to highest temperature for steelmaking operations such as ladle applications, sidewall, roofs, burner blocks, anchor brick for reheating furnaces and many other areas.
3.transition and cooling zones of rotary cement kilns, lime kilns , etc.
4.lower sidewall and bottom of aluminum refining,melting furnaces ,etc.
