Огнеупорные кирпичи для воздухонагревателя

Characteristics: 1. adopt the high quality bauxite 2. dry press and make sure the accurate dimensions 3. then burned in tunnel kiln 4. good cold crushing strength and thermal shock resistance Zibo Shunzhou Refractory Co.,ltd is a specialized manufacturer and supplier of refractory, we can supply many kinds of refractory products, such as high alumina bricks,fireclay bricks,low porosity fireclay bricks, insulating bricks and many kinds of refractory castable,ramming mass etc. We have exported to USA, India, Germany, Canada etc many countries, and they are satisfy with our products. Refractory bricks is dense shaped refractory material.with high refractoriness and mechanical behavior under high temperature, refractory bricks is the nacessary material of high-temperature services, mainly used for industrial furnaces and kinls and several thermal equipments. For high alumina brick the temperature of refractoriness under load is normally above 1420 1550c that is higher than the fireclay brick and it increases along with the al2o3 content enhances.For high alumina brick the thermal shock resistance is mainly decided by chemical contents and its mineral microstructure but its thermal shock resistant is worse than the fireclay brick. High alumina brick have very good ability of anti-acidity, anti-metal fluid corrode and anti-oxidation.High alumina brick are used normally in industry furnaces such as blast furnace, hot-blast furnace and eaf etc.The tech data: RefractoryBricks for Hot Blast Stoves Index ItemFireclay BrickHigh Alumina BrickSK-34SK-35SK-36SK-37AL2O3 % ≥42485565A.P. % ≤24242424C.C.S (Mpa) ≥30404550 Refractoriness(C)≥17501750177017900.2mpa Refractoriness under loadT0.6 ≥1400142014701550Linear Change%1500C×2h--+0.1 -0.4+0.1 -0.41450C×2h0 -0.4+0.1 -0.4--
