七十年代后期至八十年代初期,美国、加拿大等国的一些航空工厂相继对他们的热处理部门进行了技术改造,取得了良好的效果。航空工厂的热处理技术改造工作,是由下列因素所促进的: 一、热处理技术落后,与实现“未来航空工厂”的兰图不相适应欧美航空工厂虽然在采用先进热处理技术方面作了一定的工作,但一般说来,工艺仍较落后,设备也较陈旧,自动化水平不高。以美国波音飞机公司为例,在该公司所属五个分部中,共有热处理设备245台,包括时效炉,淬、回火炉,盐浴炉,槽,渗碳炉,吸
From the late 1970s to the early 1980s, some aerospace factories in the United States, Canada and other countries carried out technological improvements successively in their heat treatment departments and achieved good results. Aerospace factory heat treatment technology transformation work is promoted by the following factors: First, the heat treatment technology behind, and the realization of “future aviation factory” is not compatible with the map European and American aviation factory although the use of advanced heat treatment technology to do some work , But in general, the technology is still relatively backward, the equipment is also relatively old, the level of automation is not high. Taking the U.S. Boeing Aircraft Company as an example, there are 245 heat treatment equipment in its five branches, including aging furnace, quenching and tempering furnace, salt bath furnace, trough, carburizing furnace, suction
