热处理是大量消耗能源的加工过程。搞好节能热处理是热处理工作者的重要任务。热处理节能可以从三方面采取措施,即设备措施(绝热材料应用,废热利用,仪表应用等),材质方面的措施(如选用快速渗碳用钢、等温淬火用钢、直接正火用钢等)以及工艺技术措施。本文从改进现行工艺入手,讨论实现节能热处理的措施。一、缩短加热保温时间热处理“加热时间”的概念,目前还不完全一致。有的人提出,加热时间=升温时间+保温时间(即工件在炉内时间)。我们认为,对于比较大型铸、锻件热处理而言,
Heat treatment is the process of consuming a large amount of energy. Do a good job of energy-saving heat treatment heat treatment workers an important task. Energy-saving heat treatment measures can be taken from three aspects, namely, equipment measures (insulation materials, waste heat utilization, instrumentation, etc.), material aspects of the measures (such as the selection of rapid carburizing steel, austempering steel, And technical measures. This article starts with the improvement of current technology and discusses the measures to realize energy-saving heat treatment. First, to shorten the heat holding time Heat treatment “heating time ” concept, is not yet entirely consistent. Some people suggested that the heating time = heating time + holding time (that is, the workpiece in the furnace time). We think, for the larger castings, forging heat treatment,
