正在全路推广的“铸钢水浴清砂”法,最近在我厂生产的8K电力机车牵引电机机座上得到应用。原来采用的“水爆清砂”,由于是高温下激冷,形成了许多肉眼看不见的毛细裂纹,给机车车辆的运行安全带来潜在危险。“水浴清砂”法正是解决这一问题的有效途径。 Is being promoted throughout the “cast steel water bath sand” method, recently produced in our plant 8K electric locomotive traction motor base is applied. The originally used “water blasting sand”, because it is chilling at high temperatures, the formation of many invisible capillary cracks, to run the safety of rolling stock vehicles potentially dangerous. “Water bath clear sand” method is an effective way to solve this problem.
