一、对象选择: 热处理装料辅具的使用寿命、重量、耐高温强度和急冷急热性能等直接影响其处理产品功能。且与产品质量和生产成本密切相关。过去我厂两台75KW箱式电炉,均采用自行设计的成套活动炉底板、钢球、导轨装料辅具,材料为1Cr18Ni9Ti不锈钢铸件,全部外购。使用寿命短,不易修复使用,使生产成本增加。因此,选择装料辅具作为价值分析对象。 First, the object of choice: Heat Treatment Auxiliary life expectancy, weight, high temperature strength and rapid cooling performance directly affect their processing product features. And with product quality and production costs are closely related. In the past I plant two 75KW box-type electric furnace, are used to design their own set of activities floor furnace, steel ball, rail loading aids, materials 1Cr18Ni9Ti stainless steel castings, all purchased. Short life, not easy to repair, so that the cost of production increased. Therefore, the choice of loading aids as the value of the object of analysis.
