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 .
流化床式垃圾焚燒爐用耐火材料與循環(huán)流化床鍋爐用耐材類似，特別指出的是鍋爐衛(wèi)燃帶處、料床四周、側(cè)壁下部及分離器區(qū)域要求，具有能經(jīng)得住砂子等固態(tài)物質(zhì)激烈流動(dòng)的耐磨損性，首選材料是高鋁耐磨澆注料。
Streamization bed the type rubbish burns the stove with the refractory with the streamization circulating the bed loiler ic similar with cndure the material .What special points out is boiler Wei Ran belt place and material bed are around and side wall lower part and the burster region requirement possesses to pass through lives admittedly form intense mobile wear-resisting damages of matter such as sand etc . It is wear-resesting pouring of the hight-aluminium material that material is selected a suitable person by the head .
