目前,国内各油泵油咀厂生产的偶件,采用的热处理设备和工艺有所不同,在产品质量、文明生产、气源和成本等方面也分别存在一些问题。本文就应用箱式滴控炉进行三对偶件热处理的结果予以探讨。一、箱式滴控炉的特征箱式滴控炉是可控气氛热处理用的一种较先进的设备。我厂所用的 RM-75-9D 型箱式滴控气体渗碳炉是南京电炉厂产品,额定功率为75 kW,使用温度为950℃,炉膛尺
At present, the domestic oil pump Tsui factory production of the couple, the use of heat treatment equipment and processes are different, in product quality, civilized production, gas source and cost are also some problems, respectively. In this paper, the application of box-type drip furnace heat treatment of the three pairs to be discussed. First, the characteristics of box drip furnace Box drip furnace is controlled atmosphere heat treatment with a more advanced equipment. RM-75-9D box-type drip-controlled gas carburizing furnace used in our factory is a product of Nanjing Electric Furnace Factory, rated at 75 kW, operating temperature is 950 ℃, hearth
