7×(3+9+15×0.22)+0.20HT钢丝帘线在全钢巨型工程机械子午线轮胎中的应用

Application of 7×(3+9+15×0.22)+0.20HT Steel Cord in Giant Off-the-road Radial Tire

研究7×(3+9+15×0.22)+0.20HT钢丝帘线在33.00R51全钢巨型工程机械子午线轮胎中的应用。结果表明,以7×(3+9+15×0.22)+0.20HT钢丝帘线替代7×(3+9+15×0.245)+0.245HT钢丝帘线用于全钢巨型工程机械子午线轮胎胎体和带束层,成品性能满足国家标准要求,产品经矿山使用验证未出现因钢丝帘线变化引起的不良反馈,同时可减小轮胎质量,降低生产成本。

The application of 7 × （3 ＋ 9 ＋ 15 × 0.22） ＋ 0.20 HT steel cord in 33.00R51 giant off-the-road radial tire was investigated. The results showed that,by using 7×（3＋9＋15×0.22）＋0.20HT steel cord instead of 7× （3＋9＋15×0. 245）＋0. 245HT steel cord in the carcass ply and belt of giant off-the-road radial tire, the performance of finished tire met the requirements of national standard, there was no adverse effect found in mining applications, and the tire weight and production cost were reduced.
