普通耐火浇注料

普通耐火浇注料 Ordinary refractory castables 本产品是以粘土和高铝质原料为骨料和粉料，加结合剂制成的耐火浇注料。主要用于各种工业窑炉等热工设备内衬及化工行业各种窑炉。产品具有较高的耐火性能、良好的热震稳定性，并具有一定的抗硫酸盐侵蚀性能。其使用温度一般在 1350-1400℃，如要提高使用温度，可采用氧化铝水泥及调整颗粒级配。产品还具有抗菌素酸性、碱性良好性能，而且强度高，烧后无裂缝剥落现象。 These products mainly use chamotts and bauxite as aggregate and fine. They have high refractoriness. good sulphate corrosion resistance, Their service temperature is within 1350-1400 ℃, If service temperature is called for higher degree, particle size distribution can be addition usted and binder can be substiute by alumina cemen thus castables have acid-resistance, alkaliresistance, acid-resistance and high strength, spall resistance properties. 性能 properties 牌号 Brands A608 高铝质 Bauxite castable A609 粘土质 Chamotte castable 化学成份 Al2O3 ≥75 ≥55 Chemical Composition,% Fe2O3 ≤1.5 ≤2.0 耐火度 Refractoriness,℃ 1770 1650 体积密度，BD，（110℃×24h),g/cm3 2.5 2.4 耐压强度 CCS，Mpa 110℃×24h ≥45 ≥35 1400℃×3h 65-88 55-60 抗折强度 MOR,Mpa 110℃×24h ≥4.8 ≥4.5 850℃×3h ≥11.5 ≥6.5 荷重软化温度 RUL,℃ 1450 1370 线变化率 PLC,% 1350℃×3h +0.2 +0.18 1450℃×3h -0.6 -0.2 热震稳定性，（800℃水冷）,次 Thermal shock resistance (800℃-water quench), cycles 18 18 硅线石类、棕刚玉类耐火材料 Sillimanite and brown corundum refractories 本产品主要适用于各种锅炉及冶金、化工、建材行业的耐磨高温部位。硅线石耐火浇注料适用于流化床锅炉的燃烧部位。 These products are suitable for various kinds of boilers and the zones, which need good abrasion resistance and refractoriness in metallurgical industry. chemical industry and building material industry.
