| 中文摘要: |
| 研究2＋7×0.30ST钢丝帘线在全钢载重子午线轮胎带束层中的应用。结果表明：与3×0.20＋6×0.35HT钢丝帘线相比，2＋7×0.30ST钢丝帘线的线密度减小，最小破断力和覆胶率增大；以2＋7×0.30ST钢丝帘线替代3×
0.20＋6×0.35HT钢丝帘线用于全钢载重子午线轮胎带束层中，成品轮胎的充气外缘尺寸、强度性能和耐久性能均达到国家标准要求，且生产成本降低。 |
| 英文摘要: |
| The application of 2＋7×0.30ST steel cord in the belt of all-steel truck and bus radial tire was studied.The results showed that compared with 3×0.20＋6×0.35HT steel cord，the linear density of
2＋7×0.30ST steel cord decreased，and the minimum breaking force and adhesive coverage rate increased.Replacing 3×0.20＋6×0.35HT steel cord with 2＋7×0.30ST steel cord in the belt of all-steel truck and bus radial tire，the inflated overall diameter，strength and durability of the finished tire met the national standard requirements，while the production costs reduced. |
