62Si2MnA 钢钟用发条,在热处理中易氧化脱碳。氧化增加抛光工序的困难,脱碳影响其力学性能,要求使用淡性的保护气氛加热。为此,我们研究试用了用酒制备吸热式保护气氛。乙醇裂解后所得气氛碳势比较高,具有高的渗碳能力,可作为高碳钢保护加热气氛。乙醇中加入水后,其裂解所得气氛的碳势也随之下降。一摩尔的乙醇加入一摩尔的水的混合液,裂解后可以得到与甲醇裂解所得相
62Si2MnA clock with a clock, easy to oxidative decarbonization in the heat treatment. Oxidation increases the difficulty of the polishing process, decarburization affects its mechanical properties, requires the use of light protective atmosphere heating. For this reason, we studied the use of alcohol to prepare a heat-absorbing protective atmosphere. Ethanol after cracking the resulting carbon potential is relatively high, with high carburizing ability, can be used as a high-carbon steel to protect the heating atmosphere. After adding water to ethanol, the carbon potential of the resulting cracking atmosphere also decreases. A mole of ethanol is added to a mixture of one mole of water, after pyrolysis can be obtained with the methanol cracking phase
