HX micro-powder bonded“3-high"refractory ball This product is third generation of refractory ball. Because the micropowder technology is introduced. Its hot property is higher. The service life is as long as blast furnace campaign. It increases the wind temperature to more than 1200°C. The energy saving is excellent. Atpresent time it is the first choice for ball-type hot stove.brandHXSG-65AL2O3(%)65-70FE2O3(%) ≤1.5refractoriness(°C)≥1790apparent porosity(%) ≤22bulk density(g/cm3)≥2.6cold crushing strength(N/ball)≥25000linear change after reheating(%)[1450°C×2h]0-0.2refractoriness under load(°C)≥1550hot creep rate(%)[0.2MPa×1400°C×5h]≤0.3thermal conductivity(W/m·K)1100°C≥0.4thermal shock resistance,(times)[1100°C-water-cooling]≥24applicationball-type hot stove HX high-strength low-creep high-alumina ballThis product is the second generation based on the base of high-strength high-alumina ball. having the advantages of good hot creep property. Its service life is as long as one campaign of blast furnace heavy repair. It can increase the wind temperature of hot stove more than 1100°C. efficiently saving coal gas. the energy saving is excellent.brandHXGD-65AL2O3(%)≥65FE2O3(%) ≤1.5refractoriness(°C)≥1790apparent porosity(%) ≤23bulk density(g/cm3)2.5-2.6cold crushing strength (N/ball) ≥23000linear change after heating(%)[1450°C×2h]0-0.2refractoriness under load (°C)≥1550hot creep rate(%)[0.2MPa×1400°C×5h]≤0.5thermal shock resistance,(times)[1100°C water-cooling]20applicationball-type hot stove
