研究7×7×0.22+0.15HT钢丝帘线在巨型工程机械子午线轮胎中的应用。结果表明,7×7×0.22+0.15HT高强度钢丝帘线用于标准单胎负荷低于50t的巨型工程机械子午线轮胎胎体,轮胎性能达到国家标准要求,用户反映良好。
The application of 7 × 7 × 0.22 + 0.15HT steel cord in giant construction machinery radial tire was studied. The results show that the 7 × 7 × 0.22 + 0.15HT high-strength steel cord is used for the radial tire carcass of giant construction machinery with the single-child load less than 50t. The performance of the tire meets the requirements of the national standard and the user’s feedback is good.
