7×(3+9×0.245)+0.20HT钢丝帘线在巨型工程机械子午线轮胎胎体中的应用

Application of 7×(3+9×0.245)+0.20HT Steel Cord in Carcass of Giant Off-The-Road Radial Tire

研究7×(3+9×0.245)+0.20HT钢丝帘线在巨型工程机械子午线轮胎胎体中的应用。结果表明:与7×(3+9+15×0.175)+0.20HT钢丝帘线相比,7×(3+9×0.245)+0.20HT钢丝帘线的直径和覆胶帘布厚度减小,以其替代7×(3+9+15×0.175)+0.20HT钢丝帘线用于30.00R51巨型工程机械子午线轮胎胎体,可以满足生产工艺要求,提高轮胎的耐久性能,同时可降低生产成本。

The application of 7×(3+9×0.245)+0.20HT steel cord in the carcass of giant off-theroad radial tire was investigated.The results showed that,compared with 7×(3+9+15×0.175)+0.20HT steel cord,7×(3+9×0.245)+0.20HT steel cord possessed smaller diameter and the thickness of coated cord fabric was also thinner.By using 7×(3+9×0.245)+0.20HT steel cord instead of 7×(3+9+15×0.175)+0.20HT steel cord in the carcass of 30.00R51 giant off-the-road radial tire,the production process could meet the requirements,the endurance of the finished tire was improved,and the product cost was reduced.
