The utility model provides a cleaning device for transverse water spraying and dust removing water between frames. The cleaning device for cross spraying water and dust removing water between racks comprises a finishing mill stand, a cross spraying water device between racks and a dust removing water cleaning device. The cross spraying water device between racks is arranged between a plurality of the finishing mill racks, and the dust removing water cleaning device is arranged at the side of the finishing mill rack, and the finishing mill rack comprises a downstream mill rack biting steel to open the finishing mill rack. The downstream rack biting switch is arranged on the finishing mill rack, and the downstream rack biting switch is connected with the cross spraying device between the rack and the dust removing water cleaning device. The utility model provides a cross-spraying water and dust-removing water cleaning device between racks, through adjusting the cooling water control time sequence of finishing rolling, effectively controlling the head rolling or folding phenomenon when rolling thin specifications below 2.75 mm, resulting in the head rolling and folding down to 5% of the secondary products, improving the rolling efficiency and the qualified rate of quality.
【技术实现步骤摘要】
机架间横喷水和除尘水清洁装置
本技术涉及钢铁生产设备领域,尤其涉及一种机架间横喷水和除尘水清洁装置。
技术介绍
精轧轧制2.75mm以下薄规格时,由于带钢头部温度低,非常容易造成头部100m左右轧烂,严重时造成轧断等废钢事故。操作人员往往在L2上将机架间横喷水、防剥落水等强制关闭。这样,虽然带钢头部穿带命中率大大提高,而带钢表面一些异物不能及时清除,在下游机架进行轧制,造成带钢表面有压坑,氧化铁皮压入等一些表面质量问题,造成二级品甚至三级品,影响合格率。
技术实现思路
为解决上述的技术问题,本技术提供一种轧制2.75mm以下薄规格时,异物不能及时清除,提高合格率的机架间横喷水和除尘水清洁装置。本技术提供的机架间横喷水和除尘水清洁装置包括精轧机架、机架间横喷水装置及除尘水清洁装置,所述机架间横喷水装置设于多个所述精轧机机架之间,所述除尘水清洁装置设于所述精轧机架侧部,所述精轧机架包括下游机架咬钢开关,所述下游机架咬钢开关设于所述精轧机架上,所述下游机架咬钢开关与所述机架间横喷水装置及所述除尘水清洁装置连接。在本技术提供的机架间横喷水和除尘水清洁装置一种较佳实施例中,所述机架间横喷水装置包括横喷水开关,所述机架间横喷水开关设于所述机架间横喷水装置上。在本技术提供的机架间横喷水和除尘水清洁装置一种较佳实施例中,所述除尘水清洁装置包括除尘水开关,所述除尘水开关设于所述除尘水清洁装置上。在本技术提供的机架间横喷水和除尘水清洁装置一种较佳实施例中,所述横喷水开关为HMI按钮。在本技术提供的机架间横喷水和除尘水清洁装置一种较佳实施例中,所述除尘水开关包括2.75mm以下轧钢传感 ...
