Description
Technical field
The utility model relates to a kind of lower spray apparatus for TEMPERATURE FOR HOT STRIP LAMINAR cooling, to improve cooling quality and the production stability of steel band, belongs to steel rolling equipment field.
Background technology
Section cooling is as a part of controlled rolling and controlled cooling technique, the structure and properties of direct influence zone steel, the cold roller-way of layer is longer rollgang simultaneously, require in roller-way, to be with steel to operate steadily, so laminar cooling process becomes very important link in hot rolling mill production process.The lower spray apparatus of current section cooling is mainly based on the form that side shield and removable cover and sparge pipe combine, the frequent in actual use produced problem of this structure has: side shield is not wear-resisting, easily marked groove mark by steel edge portion even to grind leakage, and then hinder the operation of band steel to cause steel scrap; Baffle plate bearing fixed screw loosens, and baffle plate cannot accurately be located, and easy grinding roller road, causes dead roller, makes band steel fluctuation of service and causes band steel scratch on the bottom surface; Without cover plate between roller-way, because roller-way spacing is comparatively large, strip steel head has during discount trend and easily pierces trench steel scrap, lower sparge pipe water shortage or blocking cause strip property to occur fluctuation does not even conform to.Occur to stop problems, be necessary to be optimized transformation to the lower spray apparatus of section cooling, reduce and stop the appearance of above problem after transformation, make the production of band steel more stable, product combination property is improved.
Utility model content
Technical problem to be solved in the utility model is to provide the lower spray apparatus of a kind of TEMPERATURE FOR HOT STRIP LAMINAR cooling, the lower spray apparatus of this section cooling can realize the cold lower spray apparatus integration of layer, stop the heap steel because being with the button nose of steel to cause, avoid the scuffing because steel band injustice surely causes and device damage simultaneously, the steel band performance inconsistency that the deficiency because of the water yield causes can also be eliminated, thus improve the stability and equipment replacement cycle of producing, for factory reduces mass loss and spare parts consumption.
The technical scheme solved the problems of the technologies described above is:
A kind of lower spray apparatus of TEMPERATURE FOR HOT STRIP LAMINAR cooling, it is made up of cover plate, storage box, water pipe, active side baffle plate, transmission side baffle plate, storage box is welded to connect below cover plate, active side baffle plate, transmission side baffle plate are vertically welded in cover plate both sides respectively, one end and the storage box of water pipe are welded to connect, the other end of water pipe is connected with delivery hose, and cover plate has hole for water spraying, and cover forward end lower planes intersects triangle respectively to intermediate, inclined.
The lower spray apparatus of above-mentioned TEMPERATURE FOR HOT STRIP LAMINAR cooling, described cover plate has multiple hole for water spraying arrange to parallel direction along cover plate with roller shaft, the axis of hole for water spraying becomes 20-40 degree angle with cover plate bottom surface.
The lower spray apparatus of above-mentioned TEMPERATURE FOR HOT STRIP LAMINAR cooling, described cover plate is arranged between the cold rotation roller roller of layer, corresponding with upper spray apparatus, cover forward end has the angle of inclination of 10-30 degree along rolling direction and roller roller horizontal center line, and the gap between the wedge angle of cover forward end and roller-way face is 0.5-1.0mm.
The beneficial effects of the utility model are:
Cover forward end of the present utility model and roller roller horizontal center line have angle of inclination, and discount band steel does not reach cover plate, also cannot creep into below cover plate; Cover plate directly has hole for water spraying, solves the lower water spray problem after increasing cover plate on the one hand, also solve lower water spray angle in former design on the one hand and be difficult to the problem adjusted.The utility model can make lower spray apparatus reach integral installation, integral demounting, can bear larger impact, is applicable to steel rolling production-line and uses, and same injection flow rate at present and water spray water curtain direction are ensured, end properties is stablized.The utility model reduces spare part loss in production process, ensure that lower water spray stability, makes the stable of end properties, has Low investment high repayment Utilization prospects.

Fig. 2 is the top view of Fig. 1;
Fig. 3 is installation site of the present utility model schematic diagram;
Fig. 4 is the top view of Fig. 3.
In figure, mark is as follows: cover plate 1, storage box 2, water pipe 3, hole for water spraying 4, active side guide plate 5, transmission side guide plate 6, roller roller 7.
Detailed description of the invention
The utility model is made up of cover plate 1, storage box 2, water pipe 3, active side guide plate 5, transmission side guide plate 6.
Fig. 1,2 displays, storage box 2 is welded to connect below cover plate 1, and cover plate 1 and storage box 2 are welded into entirety.Active side baffle plate 5, transmission side baffle plate 6 are vertically welded in cover plate 1 both sides respectively, and one end and the storage box 2 of water pipe 3 are welded to connect, and the other end of water pipe 3 adopts with the delivery hose of rolling line turbid circulating water system and is threaded.
Fig. 1,2 displays, cover plate 1 has multiple hole for water spraying 4 arrange along the direction that cover plate 1 is axially parallel with roller roller 7, the axis of hole for water spraying 4 becomes 20-40 degree angle with cover plate 1 bottom surface.Cover plate 1 is directly opened the scheme of hole for water spraying 4, solves the lower water spray problem after increasing cover plate 1 on the one hand, also solve lower water spray angle in former design on the one hand and be difficult to the problem adjusted.
Fig. 1 shows, and cover plate 1 front end lower planes intersects triangle respectively to intermediate, inclined, and leg-of-mutton wedge angle is relative with roller roller 7 when mounted.
Fig. 3,4 displays, cover plate 1 is arranged between the cold rotation roller roller 7 of layer, corresponding with upper spray apparatus, and cover plate 1 front end edge rolling direction and roller roller 7 horizontal center line have the angle of inclination of 10-30 degree.Like this, form in strip steel head and roller-way cover plate 1 forward position " dead band " that highly reaches 65mm, make discount band steel not reach cover plate 1 easily.Utilize the gap between wedge angle adjustment cover plate 1 forward position of cover plate 1 front end and roller-way face, can this gap be controlled at 0.5-1.0mm, rolling thin gauge strip, even if so band steel has discount, also cannot creep into below cover plate 1.
Fig. 1 shows, and the axis of the hole for water spraying 4 of an embodiment of the present utility model becomes 27 degree of angles with cover plate 1 bottom surface.
Fig. 3 shows, and the cover plate 1 front end edge rolling direction of an embodiment of the present utility model and the angle of inclination of roller roller 7 horizontal center line are 15 degree.
