垃圾处理行业焚烧炉用耐火、耐磨保温材料是我厂参照国外垃圾焚烧炉用耐火、耐磨保温材料的理化指标,结合我国有关设计应用的实际情况研制开发而成的,它具有耐磨性能好,重烧线变化小,热震稳定性好等特点。
The wearproof refractory for rubbish incinerator is developed by this factory with reference to the foreign preduct of the same kind and the practical working circumstances in China ,which has such advantages as good wearproof ability ,small reheating linear change and good thermal resistance .
CAO 控气型焚烧炉也称第二代城市生活垃圾焚烧炉 - 气化熔融,有的气化熔融炉设计的焚烧熔融部位工作温度达 1400-1600 ℃甚而 1800 ℃。因此这部分内衬耐火材料应首选高温下高强度、耐磨损、耐腐蚀、耐热震的铝锆质材料,也有选择含氧化铬 10-20% 的铝铬质材料。
It is that the life rubbish in second generation city burns the stove that CAO burns the stove---Gasifies melts the stove ,some gasify to melt ,and the stove design burns melting the position work temperature to reach 1400 -1600 ℃ even reaches 1800 ℃ .Therefore lines that the refractory should the head selects under the high temperature high strength and wear-resisting damage ,corrosion preventive and the aluminium zirconium nature material of heat-resisting shake inside this part ,and also having the aluminium chromium nature material of selection Han chromium oxide 10-20% .
