垃圾處理行業(yè)焚燒爐用耐火、耐磨保溫材料是我廠參照國(guó)外垃圾焚燒爐用耐火、耐磨保溫材料的理化指標(biāo)，結(jié)合我國(guó)有關(guān)設(shè)計(jì)應(yīng)用的實(shí)際情況研制開發(fā)而成的，它具有耐磨性能好，重?zé)�變化小，熱震穩(wěn)定性好等特點(diǎn)。
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 控氣型焚燒爐也稱第二代城市生活垃圾焚燒爐 - 氣化熔融，有的氣化熔融爐設(shè)計(jì)的焚燒熔融部位工作溫度達(dá) 1400-1600 ℃甚而 1800 ℃。因此這部分內(nèi)襯耐火材料應(yīng)首選高溫下高強(qiáng)度、耐磨損、耐腐蝕、耐熱震的鋁鋯質(zhì)材料，也有選擇含氧化鉻 10-20% 的鋁鉻質(zhì)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% .
