refractory high alumina fire brick for furnace kilns

Specifications

High alumina brick is a neutral refractory which Al2O3 content is higher than 48%, using select bauxite as main raw material, supplemented by quality flint clay, it has the property of high compressive strength , high refractoriness under load and good heat shock stability.

Mainly used in the masonry and building blast furnace, the hot-blast stove, the electric stove furnace top, the rotary kiln inside lining.

Features:
1. Low bulk density, low thermal conductivity, good thermal insulation performance
2. Refractory category allow direct contact of fire, suitable for various atmosphere
3. Good integrity with furnace lining, long service life, easy operation, could be shaped freely

Typical application:
1. Furnaces of metallurgy industry, heat treatment furnace
2. Furnaces of chemical industry and construction industry
3. Furnace of incineration of garbage, recirculating fluidized bad furnace
