| 中文摘要: |
| 分析全钢载重子午线轮胎胎里欠硫的原因，并提出相应的改善措施。通过采取根据轮胎尺寸及胶囊的直径伸张比和断面周长伸张比选择胶囊型号、增大硫化胶囊排气线的尺寸和密度、调整预定型高度和机械手装胎位置的定位精度、增大定型压力及提高胎坯定型一次合格率等措施，降低了成品轮胎胎里欠硫缺陷的发生率，提高了轮胎质量。 |
| 英文摘要: |
| The cause of under-cure inside truck and bus radial tire was analyzed，and the corrective actions were put forward.By taking the measures of selecting the capsule type according to the tire size，the diameter elongation ratio and the section perimeter elongation ratio of the capsule，increasing the size and density of the exhaust line of the vulcanization capsule，adjusting the preset height and the positioning accuracy of the tire loading position with manipulator，increasing the setting pressure，and improving the first pass rate of the green setting，the occurrence rate of under-cure inside the finished tire was reduced and the tire quality was improved. |
