我段于1979年7月份起进行了宽压条铸型浇挂轴瓦白合金的试验,到去年年底,一共试验了13万多块轴瓦,装在段修、辅修、轴检及列检运用车辆上,结果全都运用良好,未发生过轴瓦白合金脱落的情况,确保了行车安全。通过六年多的实践,证明采用宽压条铸型浇挂轴瓦白合金能提高轴瓦的浇挂质量,可防止轴瓦四角白合金脱落,省掉铲瓦边工序,每块轴瓦白合金用量可节约0.2～0.3公 I paragraph in 1979 July from the wide-pressure die-casting pad bearing white metal test until the end of last year, a total of more than 130,000 pieces of pad tested, installed in the section repair, minor repair, inspection and inspection of vehicles , The results are all well-used, there has been no off-white aluminum alloy case, to ensure traffic safety. Through more than six years of practice, that the use of wide-pressure die-casting bearing pad white alloy can improve the quality of the bearing padding to prevent the four corners of the bearing white gold off, save the shovel side of the process, the amount of each bearing tile alloy can save 0.2 ~ 0.3 public
