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 .
流化床式垃圾焚烧炉用耐火材料与循环流化床锅炉用耐材类似,特别指出的是锅炉卫燃带处、料床四周、侧壁下部及分离器区域要求,具有能经得住砂子等固态物质激烈流动的耐磨损性,首选材料是高铝耐磨浇注料。
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 .
