层冷输出辊道空冷辊的失效及改进

FAILURE OF AIR - COOLING ROLL OF LAMINAR FLOW COOLING RUN - OUT ROLL TABLE AND IMPROVEMENT

对邯钢CSP生产线层冷输出辊道空冷辊在生产中出现的失效问题进行了分析,从辊道润滑、弯曲,辊面老化、磨损方面提出了预防及处理措施,确保了输出辊道长周期稳定运行,使用寿命提高了2～3倍,保证板带成品质量,减少划伤等质量问题。

It is analyzed the failure in operation of air - cooling roll of laminar flow cooling run - out roll table in CSP line. Some precaution and treating measures proposed in roll table lubrication, roll table bending, roll surface ageing and abrasion, the long - time steady operation of run - out roll table is guaranteed, its work life prolonged by 2 to 3 times, the surface scoring reduced.
