缩短渗碳周期与强烈淬火相结合的节能热处理技术(英文)

Energy Savings Using a Combination of Carburizing Cycle Reduction and Intensive Quenching

在热处理行业,人们一直在探索降低生产成本、节约能源和减少环境污染的方法。汽车制造业在这方面将是大有作为的,其中包括:大幅度缩短渗碳时间,以节能和降低生产成本;开发新型淬火剂替代易燃、有毒的矿物油基淬火剂。采用非易燃的对环境友好的水基淬火剂进行强烈淬火(IQ)是达到这些目标的途径之一。此外,IQ还能使渗碳的扩散时间缩短50%或更多。本文论述了巴西圣保罗大学、巴西Combustol公司以及美国强烈淬火公司合作进行的采用一种强烈淬火工艺成功达到上述目标的研究成果。从长远看,这些成果对热处理工业将具有重要意义。

There is an ongoing interest in the heat treatment industry to identify methods of reducing production cost, energy consumption and to reduce environmental impact of heat treatment practices and materials. Automobile industry offers a number of opportunities in this regard including： reduction of substantial carburizing times which would result in substantial energy savings and reduction in production costs due to shorter processing times and the potential replacement of flammable and relatively toxic petroleum-based quenchants. One way of achieving these goals is to use intensive quenching processes （IQ） which utilize non-flammable and environmentally benign aqueous-based quenchants. Furthermore, IQ offers the potential of significantly reducing total carburizing diffusion times by 50% , or more. This paper will discuss the results of a collaborative study conducted by the University of Sao Paulo at Sao Carlos, Combustol, and Intensive Quenching Technologies to utilize an IQ process to successfully achieve the afore mentioned goals. These results are potentially of major importance to the heat treatment industry.
