沙钢永兴精轧短应力轧机导卫底座升级改造圆满完成近日，沙钢永兴公司轧钢厂精轧短应力轧机导卫底座升级改造项目顺利完成。此次改造成功攻克长期制约生产的设备瓶颈问题，显著提升两条线圆钢规格归并生产的效率，为轧钢稳定高效生产提供强大助力。

精轧机组在轧制流程中占据核心地位，其稳定性对最终产品的尺寸精度、表面质量及生产节奏起着决定性作用。导卫装置作为引导轧件准确进入轧辊的关键部分，其底座稳固性尤为重要。因轧钢厂将两条产线生产的圆钢规格整合为一条产线，涉及21个圆钢规格频繁切换，致使精轧短应力轧机导卫装拆次数大幅增加。原有导卫固定键尺寸仅10毫米，无法承受高频次操作产生的冲击力，导卫偏移现象频发。这不仅导致热停，影响生产进度，还因轧件稳定性欠佳，造成产品尺寸精度波动，给质量管控带来风险。

面对此难题，Ƚ..
