降低成本的微合金钢曲轴 影响曲轴生产成本的一个重要因素就是锻造后的热处理。为了取消热处理,西德和其它一些国家已采用微合金钢来取代需进行淬火和回火处理的传统碳钢。微合金钢通过在最后一道工序结束后自锻造温度开始的控制冷却来获得所需的性能。 Microalloyed Steel Crankshafts Reducing Costs An important factor that affects crankshaft production costs is the heat treatment after forging. In order to cancel the heat treatment, West Germany and some other countries have adopted micro-alloyed steel to replace the traditional carbon steel that needs to be quenched and tempered. Microalloyed steel obtains the desired properties through controlled cooling starting from the forging temperature after the end of the last process.
