| 摘 要： | 在实验室真空加热炉内进行了1.0 min冷轧链条用钢板650～690℃、2～6h的罩式退火模拟试验。结果表明,冷轧链条用钢的组织为铁索体+游离渗碳体,增加退火温度和时间,钢的组织趋向均匀,退火后钢的抗拉强度Rm为395～415 MPa;增加退火温度和时间,HRB硬度值从68.9降至65.0,伸长率由36%增加至39%。该退火工艺可用于工业性生产。

| Abstract: | The simulating batch annealing test of 1.0 mm cold rolled steel sheet for chain at 650~690 ℃ for 2~6 h has been carried out by vacuum heating fumace in laboratory.Results showed that the structure of cold rolled steel for chain was ferrite + free cementite,with increasing anncaling temperature and time the structure of steel tended to homogeneous; the tensile strength of annealed steel was 395~415 MPa,with increasing annealing temperature and time the HRB hardness value of steel decreased from 68.9 to 65.0 and the clongation of steel increased from 36% to 39%.The annealing process is available for commercial production. |
