| 中文摘要: |
| 研究0.37＋6×0.32ST钢丝帘线在商用车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，0.37＋6×0.32ST钢丝帘线直径较小，线密度较低，渗胶性能较好，可以有效减小轮胎质量，实现轮胎轻量化，降低生产成本；在12R22.5 18PR 152/149L RL501商用车轮胎带束层中采用0.37＋6×0.32ST钢丝帘线替代3×0.20＋6×0.35HT钢丝帘线，帘布压延、裁断以及轮胎成型和硫化工艺性能正常，满足生产工艺标准要求；成品轮胎耐久性能提高，强度性能满足国家标准要求。 |
| 英文摘要: |
| Application of 0.37＋6×0.32ST steel cord in belt of commercial vehicle tire was studied. The results showed that，compared with 3×0.20＋6×0.35HT steel cord，0.37＋6×0.32ST steel cord had smaller diameter，lower linear density and better rubber permeability，which could effectively reduce the tire weight，realize the tire lightweight and reduce production cost.When 0.37＋6×0.32ST steel cord was used in the belt of 12R22.5 18PR 152/149L RL501 commercial vehicle tire replacing 3×0.20＋6×0.35HT steel cord，the process performance of cord fabric calendering，cutting，tire molding and curing were normal，met the requirements of production process standards，the durability of the finished tire was improved，and the strength performance met the requirements of national standards. |
