热处理是机械制造工艺中的重要组成部分,是决定产品质量和使用寿命的关键因素,也是充分发挥金属材料潜力、节约使用材料的有效途径,因而在近30年来取得了很大的发展。解放前我国机械工业中的热处理可以说是一个空白点。一些工厂和作坊仅仅依靠个别人的祖传手艺进行处理,一些工科院校根本不设热处理专业,当然就更谈不到热处理的技术队伍了。外国资本家和官僚买办设立的工厂有几台所谓的洋设备,也多为陈旧不堪。许多私营铁工厂的热处理大都使用煤炉、焦碳炉加热。解放后在党和毛主席的独立自主、自力更生方针的指引下,二十六年来,我国机械工业中的热处理发生了很大变化,从无到有,基本上形成了在机械工业中一个有影响的专业,并组织、培养、建立了一支从生产到科研的热处理 Heat treatment is an important part of the mechanical manufacturing process, which is the key factor that determines the product quality and service life. It is also an effective way to give full play to the potential of metal materials and save the use of materials. Therefore, heat treatment has made great progress in the past 30 years. Before the liberation of China’s machinery industry in the heat treatment can be said to be a blank point. Some factories and workshops only rely on individual ancestral skills for processing, some engineering colleges do not set heat treatment professional, of course, not to mention the heat treatment of the technical team. Foreign-owned capitalists and bureaucratic compradors have factories that have so-called foreign facilities and are often outdated. Many private ironworks heat treatment mostly use the coal stove, coke oven heating. After the liberation, under the guidance of the principle of independence and self-reliance of the party and Chairman Mao, the heat treatment in the machinery industry of our country has undergone great changes over the past 26 years. From scratch, it has basically formed an influential part in the machinery industry Professional, and organization, training, the establishment of a heat treatment from production to research
