我厂热处理车间所用的盐浴炉,都是用焦炭来加热的。由于炉门设计不好,炉门和炉体之间的间隙大,经常发生“跑火”,这样便增加了车间的温度,并使炉子的寿命大大地缩短,对生产很有影响。后来我们改进了炉门的装置,清除了“跑火”现象,因而也提高了炉子的使用寿命达十倍以上。现在我们把改进后的炉门构造介绍给大家 The salt bath furnace used by our factory heat treatment workshop is heated by coke. Due to the poor design of the furnace door, the gap between the furnace door and the furnace body is large and “running fire” frequently occurs. This increases the temperature of the workshop and greatly shortens the life of the furnace and has an impact on the production. Later, we improved the oven door device, clear the “running fire” phenomenon, which also increased the life of the furnace up to ten times. Now we introduce the improved door structure to everyone
