Anchor brick:
AL2O3 content of more than 45% of the aluminum silicate refractory products, corundum, high alumina vanadium or sillimanite and other minerals as raw materials made of refractory material collectively referred to as high alumina refractories.
Has the characteristics of high refractoriness, acid and alkali slag strong erosion, high temperature mechanical strength, it is often used in masonry blast furnace, hot stove and a variety of heating furnace to improve the furnace life.
Properties:
1.High strength,
2.good thermal shock resistance,
3.Strong stripping resistance
4.High temperature resistance
5.High-temperature endurable .
6.Good spalling resistance and wear resistance.
Application:
1.Industrial furnace 2.Furnace roof
