精轧下阶梯垫是为补偿工作辊及支承辊辊径磨损及调节精轧机工作辊辊面标高的重点备件。在长时间的使用过程中,阶梯垫经常更换,是因为表面出现压痕或裂纹,导致机架轧制力出现较大偏差,影响轧钢。在一重设计结构中,吹扫水为喷嘴结构,不能够有效将阶梯垫表面存在的氧化铁粉末吹扫干净,因此寻找一种更为优化的结构来取代,是解决这个问题的关键。 Finishing the next step mat is to compensate for the work roll and roll diameter support roll and adjust the finishing mill work roll surface elevation key spare parts. In the course of prolonged use, the step mat is often replaced because of the indentation or cracks on the surface, resulting in a large deviation of the rolling force of the rack, affecting the rolling. In a heavy design structure, the purge water is a nozzle structure, which can not effectively purify the iron oxide powder present on the surface of the step mat. Therefore, looking for a more optimized structure to replace is the key to solving this problem.
