| 中文摘要: |
| 研究2×0.30ST钢丝帘线在175/65R14 82H半钢子午线轮胎带束层中的应用。结果表明：使用2×0.30ST钢丝帘线替代3×0.30HT钢丝帘线用于175/65R14 82H半钢子午线轮胎带束层，工艺性能满足轮胎生产要求，成品轮胎性能达到或高于国家标准要求；与3×0.30HT钢丝帘线相比，2×0.30ST钢丝帘线直径和线密度小，压延帘布厚度减小，有利于实现轮胎轻量化，从而降低轮胎滚动阻力、生产成本以及燃料消耗。 |
| 英文摘要: |
| The application of 2×0.30ST steel cord in the belt of 175/65R14 82H steel-belted radial tire was studied.The results showed that，using 2×0.30ST steel cord instead of 3×0.30HT steel cord in the belt of 175/65R14 82H steel-belted radial tire，the processing properties met the tire production requirements，and the performance of finished tire met or exceeded the national standard requirements.Compared with 3×0.30HT steel cord，the diameter and the line density of 2×0.30ST steel cord were smaller，the thickness of calendering cord was reduced，which was conducive to realizing tire lightweight，so as to reduce the rolling resistance，production cost and fuel consumption. |
