高温盐浴炉所产生的烟雾及毒气不但污染环境,而且对人体非常有害。同时高温盐浴炉启动升温慢,耗电量大。因此我们采用氩气保护炉来代替高温盐浴炉。一、试验装置为使钢料在1000℃以上热处理而不脱碳、不氧化,我们改装了KO-11型碳硅棒炉。在炉内加放一个瓷套管(图1),将试样放在套管内,氩气直接通入瓷套管,使之产生对流。氩气把易脱碳氧化的气体排除起到保护作用。瓷管密封,必须保持充满氩气,并使其它气体排出。经反复试验,取得了良
High temperature salt bath smoke and gas generated not only pollute the environment, but also very harmful to humans. At the same time high temperature salt bath furnace slow start, power consumption. Therefore, we use argon gas furnace instead of high-temperature salt bath furnace. First, the test device To make the steel in the heat treatment above 1000 ℃ without decarbonization, no oxidation, we modified the KO-11-type carbon silicon furnace. Put a ceramic sleeve in the furnace (Figure 1), the sample is placed in the sleeve, argon gas directly into the ceramic sleeve, so that convection. Argon gas easy to decarburization oxidation play a protective role. Porcelain tube seal, must be kept full of argon, and other gases out. After repeated tests, made good
