轴承钢管尺寸规格表
详细说明:

 研究了带芯棒的GCr15轴承钢管的双向剪切方法,尤其是首次压下量对剪切品质的影响;轴承钢是生产轴承滚动体和套圈的钢种,常用钢种为GCr15。本钢采用中方坯(235 mm×265 mm)生产的轴承钢在使用过程中出现了内部裂口,该裂口平直、通长。因为产生轴承钢管内部裂口的原因很多,所以对产品出厂检验结果进行检查,全部符合GB/T18254要求。然后将钢管垂直于裂口处沿纵向割开,用金相、电镜对裂口和基体分析,找出了轴承钢内部裂口产生的原因为在冷拔过程中机械划伤所致。 对实验结果进行了分析,并在此基础上,对双向剪切法进行了改进,得到了较好的断面品质。轴承钢管是轴承钢二火成材产品,作为轴承套圈用钢,其生产有其特殊性和严格要求。由于国家整体冶炼水平及生产企业自身存在的问题和轴承套圈加工技术的发展,轴承钢管在质量,生产成本,材料利用率等方面优势不明显,其发展空间受到挤压。
