| 中文摘要: |
| 分析全钢载重子午线轮胎钢丝帘线压延工艺中钢丝帘线重叠交叉、跳线、覆胶喷霜、露钢丝等质量问题。通过调整整经辊和压力辊，降低供胶温度和压延速度、减小供胶机胶容量、确保适合的钢丝张力值等措施，钢丝帘线的压延质量大幅提高，压延质量缺陷率小于0.2%。 |
| 英文摘要: |
| The calendering quality defects of steel cords for all steel TBR tires were analyzed， including inhomogeneous density of steel cords， overlapping， curved cords， bending， crossing， blooming， exposed cords and so on. And then effective measures were proposed. For example， the warping rollers and pressure rollers were modified， the temperature and rolling speed were reduced， and the cord tension was adjusted. The calendering quality of steel cords was greatly improved by implementing those changes， and the defect rate by X-ray inspection was reduced below 0.2%. |
