Self-protection silicon carbide corrosion-resistant material for water-cooled wall of pulverized coal gasification furnace
The invention relates to a self-protection silicon carbide corrosion-resistant material for a water-cooled wall of pulverized coal gasification furnace. The material is prepared from the following rawmaterials in percentage by mass: 25 to 35 percent of 3-1mm acid-pickled silicon carbide, 25 to 35 percent of 1mm-180-mesh acid-pickled silicon carbide, 5 to 10 percent of 180-200-mesh acid-pickled silicon carbide, 0 to 10 percent of 200-325-mesh acid-pickled silicon carbide, 0 to 10 percent of 3000-mesh or less acid-pickled silicon carbide, 3 to 20 percent of alumina micro-powder, 3 to 20 percentof a binding agent, 1 to 15 percent of a phosphoric acid solution, and 1 to 10 percent of magnesia. The self-protection silicon carbide corrosion-resistant material for the water-cooled wall of the pulverized coal gasification furnace has excellent mechanical properties, thermal shock resistance, slag corrosion resistance and the like, and has great significance in improving the system operationefficiency, reducing the production cost and saving resources and energy.
本发明涉及一种煤粉气化炉水冷壁用自保护碳化硅耐腐蚀材料，该材料包括以下质量含量的原料：3‑1mm酸洗碳化硅25～35％，1mm‑180目酸洗碳化硅25～35％，180‑200目酸洗碳化硅5～10％，200‑325目酸洗碳化硅0～10％，3000目以下酸洗碳化硅0～10％，氧化铝微粉3～20％，结合剂3～20％，磷酸溶液1～15％，镁砂1～10％。本发明提供的煤粉气化炉水冷壁用自保护碳化硅耐腐蚀材料具有优越的力学性能、抗热震性能及抗熔渣腐蚀等性能，对提高系统运转效率，降低生产成本，节约资源和能源具有重大意义。
