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) + 0.20HT steel cords in 33.00R51 all-steel giant construction machinery radial tire was studied. The results show that 7 × (3 + 9 + 15 × 0.22) + 0.20HT steel cords instead of 7 × (3 + 9 + 15 × 0.245) + 0.245HT steel cords are used in all-steel giant mechanical radial tire carcass And belt, finished product performance to meet the national standard requirements, the use of the mine verified by the mine did not appear due to changes in steel cords adverse feedback, while reducing the quality of the tire and reduce production costs.
