Application Comparison of 2×0.30ST Steel Cord from Different Producing Areas in Tire

研究不同产地2×0.30ST钢丝帘线在轮胎中的应用对比。结果表明:不同产地2×0.30ST钢丝帘线性能相差不大,应用于225/65R17102H轿车子午线轮胎带束层中,压延、裁断、成型和硫化工艺均正常,成品轮胎的充气外缘尺寸、强度、脱圈阻力、耐久性能、低气压性能和高速性能相差不大,符合相应国家标准和企业标准要求;骨架材料本地化,有利于降低生产成本,提高经济效益。

The application comparison of 2×0.30ST steel cord from different producing areas in tires was studied.The results showed that there was little difference in the properties of 2×0.30ST steel cord from different producing areas.When they were applied in the belt of 225/65R17 102H passenger car radial tire,the calendering,cutting,building and vulcanization processes were normal,and there was little difference in the inflation peripheral dimension,strength,bead unseating resistance,durability,low air pressure performance and high speed performance of the finished tire,which met the requirements of corresponding national standards and enterprise standards.With localization of the skeleton materials,the tire production cost was reduced,showing economic benefits.
