[0002] With the rapid development of the steel industry, the speed of the process section of the pickling and leveling production line is also constantly increasing. For example, the hot-rolled pickling and leveling production line of Nippon Steel can produce pickling and leveling products of 0.8-4.0mm, and the process section speed reaches 400m / min. Continuous high-speed operation of the process section is the guarantee of high production, but in the high-speed production process, if abnormal conditions such as strip breakage occur and when handling production failures, the strip is easy to collide with the compressed air nozzle and spray beam, causing damage to the nozzle and spray beam, affecting the surface quality of the strip.

[0003] However, the existing pickling and leveling machine spray device requires manual adjustment of the nozzle angle during use, which invisibly increases the workload and is prone to the situation where the adjustment is not in place and needs repeated adjustment, which affects the work progress. Moreover, most of the spray devices are installed at a fixed height on the pickling and leveling machine, which makes it impossible to spray strips of different heights. Therefore, an automatically reversing spray device for a pickling and leveling machine is provided. Utility Model Content
