High alumina brick is kind of alumina silicate refractory material, made of superior bauxite and other additives at high temperature, with Al2O3 content above 48%. Fire clay brick al2o3 content is below 48%, but with good thermal shock resistance. Province Henan Xinmi city is one of the biggest high alumina brick production base.

SIJIHUO REFRACTORY has successfully provided bulk refractory bricks and professional refractory material solutions to various industrial furnaces for oversea markets. Referring to cement industry, lime kiln, glass kiln etc.

Low-creep high alumina brick is with superior bauxites with special additives, after High pressure molding, high temperature firing, with small creep rate and become the Low creep high alumina refractory brick. It is suitable for medium and small blast furnace supporting hot stove.

Classification by material: High alumina brick / Silimanite brick /Mullite brick / Corundum brick / Corundum-mullite brick

• Higher refractoriness under loading
• Good thermal shock resistance
• Good chemical erosion resistance

High alumina brick is widely used in blast furnace, EAF, steel ladle, boiler, lime/cement kiln, glass kiln etc.

Different furnaces refractory linings should be matched with suitable fire bricks, with suitable specifications and related shapes.

Standard shapes including: straight shape, side wedge, tip wedge etc. see below brick shapes list, customized drawings are acceptable.
