| 中文摘要: |
| 介绍新型钢丝帘线3+9+15×0.245HT，3+8×0.35HT BETRU和5×0.35HI在矿山型全钢载重子午线轮胎中的应用。与3+9+15×0.22+1NT和3×4×0.22HE钢丝帘线相比，3+9+15×0.245HT，3+8×0.35HT BETRU和5×0.35HI钢丝帘线在破断力/直径和破断力/线密度方面更有优势；胎体选用3+9+15×0.245HT钢丝帘线、1#和2#带束层选用3+8×0.35HT BETRU钢丝帘线、3#带束层选用5×0.35HI钢丝帘线，有利于延长轮胎的使用寿命，提高轮胎翻新率。成品轮胎性能试验结果表明：与采用普通钢丝帘线的轮胎相比，采用新型钢丝帘线的轮胎的充气外缘尺寸变化不大；轮胎的强度性能和耐久性能以及胎圈耐久性能提高；轮胎质量和成本变化不大。 |
| 英文摘要: |
| The application of new type steel cord 3+9+15×0.245HT，3+8×0.35HT BETRU and 5×0.35HI in mining truck radial tire was introduced.The results showed that，compared with 3+9+15×0.22+1NT and 3×4×0.22HE steel cord，3+9+15×0.245HT，3+8×0.35HT BETRU and 5×0.35HI steel cord possessed higher rupture strength/diameter and rupture strength/cord count.When the 3+9+15×0.245HT steel cord was applied in carcass，3+8×0.35HT BETRU steel cord was used in 1# and 2# belt，and 5×0.35HI steel cord was applied in 3# belt，the service life of tire was prolonged and the ratio of tire retreading was increased.It was confirmed by the test of finished tires that，compared with the tire using commonly steel cord，the inflated peripheral dimension of the tire using new type steel cord changed little，strength performance，endurance performance and bead endurance were improved，and the weight and cost of tire changed little. |
