| 中文摘要: |
| 研究全钢子午线轮胎挤出胎面底部不平的原因和解决措施。挤出胎面容易出现底部沟痕、底部不平、底部波浪等缺陷，通过口型板上板后口倒角、减小预口型厚度、增大口型板尺寸、减小预口型分型面厚度、调整口型系数和优化挤出工艺，可以使挤出胎面底部平整、光滑、无褶皱，解决胎面底部不平问题。 |
| 英文摘要: |
| In this study，root causes of uneven bottom of the extruded tread of all-steel radial tire were analyzed and improvement solutions were proposed. The bottom of the extruded tread could have defects such as groove marks，unevenness and ripples. This study showed that，by chamfering the rear exit of the upper part of die plate，reducing the thickness of the pre-die，increasing the size of the die plate，reducing the thickness of the pre-die parting surface，adjusting the die shape coefficient and optimizing the extrusion process，the bottom of the extruded tread became even and smooth，without any ripple defect. |
