Abstract
The utility model relates to a device for lubricating and cooling a finishing side guide plate. The device comprises a hot-rolled oil collecting pipe and nozzles, wherein the upper edge of the side guide plate is provided with round holes, above which the hot-rolled oil collecting pipe is arranged; the setting direction of the hot-rolled oil collecting pipe is parallel to the side guide plate; and a plurality of nozzles are arranged below the hot-rolled oil collecting pipe and positioned in the round holes at the upper edge of the side guide plate. The inclined angle of the hot-rolled oil nozzles and the side guide plate is 15 to 30 degrees, and simultaneously the hot-rolled oil nozzles can not be higher than the lower end surface of the upper edge of the side guide plate. Compared with the prior art, the device has the advantages of being capable of effectively lubricating and cooling the side guide plate of a finishing downstream rack, obviously reducing the wear of the side guide plate, prolonging the changing cycle of the side guide plate by two times, obviously reducing the side cracks and scab defects of the belt steel and obviously improving the surface quality of products.
Description
Technical field
The utility model relates to the steel rolling process technical field, is a kind of device of lubricated and cooling finish rolling side guide plate.
Background technology
In the hot continuous rolling process, band steel and the scratching of finishing mill flipper guide, cause the flipper guide wearing and tearing to be accelerated, the band steel contacts with the flipper guide of serious wear, is easy to generate limit portion breach defective, simultaneously in the scratching process, the residual gradually sticking iron of flipper guide, residue falls into follow-up belt steel surface, is pressed into steel plate by milling train, forms scab defects.
Summary of the invention
For alleviating the wearing and tearing of band steel offside guide plate, reduce strip edge portion's breach and scab defects, the utility model provides a kind of device of lubricated and cooling finish rolling side guide plate, and this device is easy and simple to handle, and result of use is better.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of device of lubricated and cooling finish rolling side guide plate, this device comprises hot-rolling oil collector, nozzle, is provided with circular hole in the flipper guide upper edge, is provided with the hot-rolling oil collector above circular hole, hot-rolling oil collector arranged direction parallels with flipper guide; Be provided with a plurality of nozzles below the hot-rolling oil collector, nozzle is positioned at the circular hole of flipper guide upper edge.
The angle of described hot-rolling oil nozzle and flipper guide is 15 °-30 °, and the hot-rolling oil nozzle must not surpass the lower surface of the upper edge of flipper guide simultaneously.
Compared with prior art, the utility model has the advantages that: can effectively lubricating and cooling finish rolling downstream frame flipper guide, the wearing and tearing that obviously alleviated flipper guide, the flipper guide replacement cycle has prolonged 2 times, strip edge portion breach and scab defects obviously reduce, and product surface quality obviously improves.

Fig. 2 is the structure vertical view of lubricated and cold side guide plate arrangement.
Among the figure: 1-flipper guide 2-circular hole 3-collector 4-nozzle 5-flipper guide upper edge
The specific embodiment
See Fig. 1, Fig. 2, a kind of device of lubricated and cooling finish rolling side guide plate, this device comprises hot-rolling oil collector 3, nozzle 4, is provided with circular hole 2 in flipper guide 1 upper edge, is provided with hot-rolling oil collector 3 above circular hole 2, hot-rolling oil collector 3 arranged direction parallel with flipper guide 1; Be provided with a plurality of nozzles 4 below hot-rolling oil collector 3, nozzle 4 is positioned at the circular hole of flipper guide upper edge 5.
The concrete operation method of this device is as follows:
1, (generally be that F4～F7) hot-rolling oil collector 3 is installed in finish rolling flipper guide upper edge 5, each collector 3 is provided with 5～6 hot-rolling oil nozzles 4, guarantees that spray regime can cover whole jig flipper guide 1 in finishing mill downstream frame.Nozzle 4 is ejected into flipper guide 1 medial surface by the circular hole on the flipper guide upper edge 52.
2, each hot-rolling oil nozzle and flipper guide keep 15 °～30 ° inclination angles, guarantee jeting effect, and the hot-rolling oil nozzle must not surpass the lower surface of the upper edge of flipper guide simultaneously, in order to avoid the band steel bumps against nozzle when wearing band or the firm accident of transaction card is bumped nozzle.
3, be connected damage collector when avoiding the guide and guards turnover between hot-rolling oil collector and the oil sources with flexible pipe.
4, guarantee system's hot-rolling oil pressure at 0.3～0.5Mpa, guarantee that the profit part by weight is 100: (0.3-0.5).
5, hot-rolling oil input time series: the band steel is worn at this rolling mill and is begun to drop into after band is finished, and the band steel stops to drop into after this rolling mill is thrown steel.
Claims (2)
1, a kind of device of lubricated and cooling finish rolling side guide plate is characterized in that this device comprises hot-rolling oil collector, nozzle, is provided with circular hole in the flipper guide upper edge, is provided with the hot-rolling oil collector above circular hole, and hot-rolling oil collector arranged direction parallels with flipper guide; Be provided with a plurality of nozzles below the hot-rolling oil collector, nozzle is positioned at the circular hole of flipper guide upper edge.
2, the device of a kind of lubricated and cooling finish rolling side guide plate according to claim 1 is characterized in that the angle of described hot-rolling oil nozzle and flipper guide is 15 °-30 °, and the hot-rolling oil nozzle must not be above the lower surface of the upper edge of flipper guide simultaneously.
