| 中文摘要: |
| 研究0.25＋6＋12×0.225HT钢丝帘线在12.00R20矿山载重子午线轮胎胎圈包布中的应用。结果表明：与3＋9＋15×0.175＋0.15钢丝帘线相比，0.25＋6＋12×0.225HT钢丝帘线直径减小，线密度和破断力增大，压延帘布生产工艺良好，以其替代3＋9＋15×0.175＋0.15钢丝帘线应用于12.00R20矿山载重子午线轮胎胎圈包布，成品轮胎的充气外缘尺寸和耐久性能符合国家标准要求，胎圈耐久性能显著提升。 |
| 英文摘要: |
| The application of 0.25＋6＋12×0.225HT steel cord in bead chafer of 12.00R20 truck and bus radial tire for mine was studied.The results showed that，compared with 3＋9＋15×0.175＋0.15 steel cord，the diameter of 0.25＋6＋12×0.225HT steel cord was reduced，the linear density and breaking force were increased，and the production process of calendered cord fabric was good.By using 0.25＋6＋12×0.225HT steel cord to repalce 3＋9＋15×0.175＋0.15 steel cord in the bead chafer of 12.00R20 truck and bus radial tire for mine，the inflated peripheral dimension and durability of finished tire met the requirements of national standards，and the bead durability was significantly improved. |
