热处理工艺是机械制造业中重要的工艺过程之一,即零部件的材料确定后,其使用性能需经过热处理才能达到最佳状态。而热处理是耗能最多的工序,故改进热处理工艺可节约大量能源,这在当前能源紧缺的情况下,是有重大意义的工作,为此我们对常用钢种进行了试验。一、缩短加热保温时间 1.试验用料为45号碳钢和35CrMo钢,其试样尺寸分别为φ20×150mm和φ50×200
Heat treatment process is one of the important process in mechanical manufacturing industry, that is, the components of the material is determined, its performance needs to be heat treated to achieve the best condition. The heat treatment is the most energy-consuming processes, so to improve the heat treatment process can save a lot of energy, which in the current energy shortage situation, is of great significance to the work, for which we tested the commonly used steel. First, shorten the heating and holding time 1. Test materials for the 45 carbon steel and 35CrMo steel, the sample size was φ20 × 150mm and φ50 × 200
