新型耐火材料高强度轻质粘土砖才问世不久,而热处理炉应用它做炉衬却日益广泛。应用这种耐火材料做炉衬具有炉体轻、升温快、保温性能好、炉温波动小、筑炉性好等优点。它完全能满足普通热处理的质量要求,是一种比较理想的新型耐火材料。1983年,我厂应用高强度轻质粘土砖做大型井式淬火电阻炉炉衬,运行一年多,开炉250余次,实践证明,各项技术特性达到设计要求。
The new refractory high strength light clay brick came out shortly before, but the heat treatment furnace used it to make the lining is more and more widely. The use of refractory lining to do with furnace light, fast heating, good insulation properties, small fluctuations in temperature, building a good furnace and so on. It can fully meet the quality requirements of ordinary heat treatment, is an ideal new refractory material. In 1983, our factory applied high-strength light clay brick as a large well-type quenching resistance furnace lining, operating for more than one year and opening more than 250 times. Practice proved that the technical characteristics meet the design requirements.
