短周期热处理,是一个相当新的理论和工艺。它与通常的铸钢件热处理时,以每厚1吋保温1小时的透烧时间,及过长时间的均匀化处理,或两次正常化处理,两次回火等常用的工艺不同。这些过长时间的长周期热处理工艺,没有哪一个明显地有助于改进铸钢件的性能,在实事上也缺乏根据。这种凭经验的戒律,牢固地建立到今天,它大量浪费金钱,时间和能源,能源节约是当前的关键,不适当的热处理工艺,大规模的浪费能源,和不完善的退 Short cycle heat treatment is a fairly new theory and process. It is with the usual cast steel heat treatment, to 1 inch per thick insulation 1 hour burn-through time, and a long time of homogenization, or two normalization, twice tempering and other common processes are different. None of these long-period, long-period heat treatment processes have significantly contributed to improving the performance of steel castings, and they are also lacking in fact. This established precepts, firmly established until today, it is a waste of money, time and energy, energy conservation is the current key, improper heat treatment process, a large waste of energy, and imperfect retreat
