Description
Technical Field
The utility model relates to a hot tandem mill equipment field, especially a hot rolling roughing mill entrance descaling water beam quick adjustment device.
Background
The slab enters a hot-rolling roughing mill (V)2) Firstly, high-pressure water descaling is needed to remove surface iron oxide. The high-pressure water descaling device comprises a dephosphorization water beam and a plurality of high-pressure nozzles arranged on the dephosphorization water beam, and the installation height of the dephosphorization water beam also determines the spraying height of the high-pressure nozzles. The spraying height of the high-pressure nozzle is important for uniformly removing the iron oxide on the surface of the plate blank. If the spraying height of the high-pressure nozzle is changed, if the spraying height exceeds the set height, the iron oxide on the surface of the slab cannot be completely removed, and the subsequent hot-rolled finished product is unqualified. If the height is lower than the set height or inclined, the surface of the slab may be excessively pressed by a washing, forming pits and the like, thereby causing subsequent defective hot rolled products.
At present, the top of the dephosphorization water beam is connected with a V through two screw rods2The balance beams are connected, the dephosphorization water beams are supported and connected on the supporting rollers, however, the supporting rollers need to be replaced once after rolling to the set tonnage, and the replacement is performed about 20 days at present. The replaced support roller needs to be polished to remove the worn part, so that the roller diameter of the support roller can be changed. When the supporting roller with the changed roller diameter is installed, V2The height of the balance beam will also vary. At this time, with V2The height of the descaling water beam connected with the balance beam changes along with the change of the height of the descaling water beam, so that the height of the descaling water beam needs to be adjusted through the adjusting screw rod, and the height of the descaling water beam is adjusted to be within the process range again. However, when the height of the dephosphorization water beam is adjusted by the screw rod, the following defects exist:
1. the adjustment time is long: the adjustment time of the screw rod needs 3-4 skilled operators to operate simultaneously, and the adjustment time is about more than 30 minutes.
2. The adjustment is difficult: the lead screw is in a severe environment, iron oxide and water corrosion often cause the lead screw to be blocked, the adjustment is difficult, and the productivity is seriously restricted from being improved.
3. And (3) dephosphorization water beam inclination: the wire withdrawing problem of the screw rod is caused by impact vibration in the rolling process of the rolling mill, so that the dephosphorization water beam is inclined, the descaling effect is poor, the defective ferric oxide product is caused, the quality objection is caused, and the product quality is influenced.
