AluminaBrick

Corundum brick

Corundum brick is an aluminum-silicon refractory product with corundum as the main phase. Corundum bricks are divided into three types: fused cast corundum brick, fused corundum sinter brick, and sintered corundum brick. Corundum brick has a series of excellent properties, high mechanical strength and high hardness.

Nanme：Corundum brick

Other name:Corundum block,AZS block,Chrome corundum brick

Characters：high mechanical strength,high hardness,good wear resistance,oxidation resistance,erosion resistance,electrical insulation properties

Application：glass melting furnace,sliding nozzle,petrochemical industrial slag oil and gas furnace

High alumina brick

High alumina brick

The high-alumina brick is an aluminum-silicon refractory product made of bauxite clinker with a certain amount of combined clay and having an Al₂O₃ content of more than 48%. The production process of high-aluminum bricks is basically the same as that of high-quality multi-cropped clay bricks. The parts of various thermal equipment that originally used silica brick or clay bricks can be replaced by high alumina bricks.

Nanme：High alumina brick

Other name:High alumina brick

Characters：Acid-resistant and alkaline slags, high refractoriness and high temperature strength

Application：Blast furnaces, hot blast stoves, electric furnace tops, steel drums, cement kiln, glass kiln

Fire clay brick

Fire clay brick

Fire clay brick is a refractory product with Al2O3 content of 30%~48% produced from refractory clay. Fire clay bricks are widely used in many thermal equipment such as blast furnaces, hot blast stoves, steel linings and steel casting systems.

Nanme：Fire clay brick

Other name:Fire clay brick

Characters：high yield,wide application,ideal bulk density, mechanical strength, thermal shock resistance and high Refractoriness

Application：blast furnaces, hot blast stoves, steel linings,steel casting systems

Silica brick

Silica brick is a refractory product containing SiO2 as a main component. Its SiO2 content is generally not less than 93%. Silica brick is an acidic refractory material. It has strong resistance to acid slag and good resistance to oxides such as CaO, FeO and Fe2O3. However, it has poor resistance to alkaline slag erosion and is easily oxidized by Al2O3, K2O and Na2O.

Nanme：Silica brick

Other name:Silica brick

Characters：strong resistance to acid slag,high refractoriness

Application：coke ovens, acidified iron furnaces, metallurgical furnace flue, steel drum lining, flow steel bricks and hot metal tanks
