一、问题的提出 我厂甲弹热处理原工艺均是采用盐浴炉、煤气炉、铅浴炉加热,存在很多问题: 其一,用盐浴炉加热,生产效率低,劳动强度大,不适于大量生产。 其二,用煤气炉加热,尽管生产率比盐浴炉有了较大的提高,但劳动强度大,小产品需要装罐很麻烦,产品质量也不稳定,且加热时氧化脱碳严重(一般脱碳层在0.1毫米以 First, the problem raised I plant a bomb heat treatment of the original process are used salt bath furnace, gas furnace, lead bath furnace heating, there are many problems: First, with a salt bath furnace heating, low production efficiency, labor-intensive, not suitable Mass production. Second, the use of gas furnace heating, although the productivity than the salt bath furnace has been greatly improved, but the labor-intensive, small product canning is very troublesome, product quality is not stable, and the heating of the oxidation of decarburization serious The carbon layer is at 0.1 mm
