Abstract
The utility model discloses a rolling mill water retaining device in hot tandem rolling mechanical equipment field, this water retaining device be including setting up the breakwater in rolling mill outlet side frame, be equipped with the cell type hole on the breakwater, the length direction in cell type hole and the width direction of breakwater are unanimous, and the bolt fastening of breakwater through passing the cell type hole is in the frame. The beneficial effects of the utility model are that: through setting up the cell type hole on the breakwater, then with the bolt fastening that passes the cell type hole in the frame, when the front end wearing and tearing back of breakwater, can loosen the bolt, move along the breakwater, reach the effect of continuation manger plate to increased the breakwater at the quick -witted rate of utilization, the life cycle has prolonged, it is extravagant to have reduced the material, has reduced manufacturing cost.
Description
Technical field
The utility model relates to hot continuous rolling technical field of mechanical equipment, particularly relates to a kind of baffle device for water for milling train.
Background technology
In hot continuous rolling widestrip mill production process, due to roll surface with band steel contact after, instantaneous temperature is higher, therefore, being in the time of the condition of high temperature in order to shorten roll surface, obtaining uniform roller heat convex degree learning and temperature must be cooled to about 150 DEG C even lower by good band plate crown as early as possible, for this reason, the cooling water arrangement that entrance side arranges 2 row's nozzles, outlet side arranges 4 row's nozzles is taken, to accelerate roll rolipass design to each root roll.If roll cooling waters a large amount of in production is trapped in belt steel surface, strip width direction temperature can be caused uneven, and then the Strip Shape Control of influence zone steel and rolling stability.This problem is particularly outstanding in mm finishing mill unit, therefore be provided with baffle device for water at every frame finishing stand inlet side, outlet side, the effect of this baffle device for water is directed away from both sides by the roll cooling water of most of finish rolling backing roll, working roll, preventing cooling water from falling on band steel plate surface causes plate temperature too low, the surface quality of influence of rolled stability and product.
Cooling due to working roll outlet side requires to be far longer than entrance side, therefore, higher to the Capability Requirement of the baffle device for water of outlet side, in outlet, baffle device for water is installed on above working roll outlet side by the installing hole on it and bolt, in use baffle device for water is understood Yin Gaowen and is caused rapid wearing with roll contact, the width of water fender is generally at 190-200mm, just need to change employ material 1/6, if changed not in time, milling train will leak and directly water on band steel, cause the temperature drop of band steel, by the as-rolled condition of influence zone steel and the surface quality being with steel.But frequently change baffle device for water, spend useless cost higher.So need to study a kind of new baffle device for water, while meeting rolling mill practice requirement, increase baffle device for water in machine service time.
Utility model content
After overcoming the wearing and tearing of existing milling train baffle device for water, need frequent replacing, cause the more high deficiency of cost, technical problem to be solved in the utility model is: provide a kind of milling train baffle device for water that can reduce replacement frequency, increase the service life.
The utility model solves the technical scheme that its technical problem adopts: milling train baffle device for water, comprise the water fender be arranged in milling train outlet side frame, described water fender is provided with grooved hole, the length direction in described grooved hole is consistent with the width of water fender, and water fender is by being bolted in frame through grooved hole.
Further, described grooved hole comprises at least three and uniform intervals is arranged on the length direction of water fender.
Further, described water fender is also provided with pressing plate, described pressing plate is bolted and abuts in water fender upper surface.
Further, the upper surface of described water fender front end and lower surface are equipped with inclined-plane.
The beneficial effects of the utility model are: by arranging grooved hole on water fender, then with being bolted in frame through grooved hole, after the nose wear of water fender, can bolt be unclamped, water fender is moved forward, reach the effect continuing dash, thus add water fender in machine utilization rate, extend life cycle, decrease waste of material, reduce production cost.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Be labeled as in figure, 1-water fender, 2-grooved hole, 3-frame, 4-bolt, 5-pressing plate.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, the utility model comprises the water fender 1 be arranged in milling train outlet side frame 3, described water fender 1 is provided with grooved hole 2, and the length direction in described grooved hole 2 is consistent with the width of water fender 1, and water fender 1 is fixed in frame 3 by the bolt 4 through grooved hole 2.Existing water fender is generally just provided with circular through hole, then be bolted in frame, just can only fall by integral replacing after water fender wearing and tearing, the grooved hole 2 that the utility model is arranged, the space that water fender 1 is had in the direction of the width is movable, when water fender 1 is after position wearing and tearing, bolt 4 can be unclamped, mobile water fender 1, its front end is contacted with working roll again, play the effect of dash, the length in grooved hole 2 can be arranged according to the active length of water fender 1, make utilize water fender 1 to greatest extent, extend its life cycle, reduce waste of material.
In order to ensure the stability of installing, water fender 1 is provided with multiple grooved hole 2, and grooved hole 2 should comprise at least three, and uniform intervals is arranged on the length direction of water fender 1, make its entirety more reliable and more stable, avoid occurring leaking and water fender 1 weares and teares the situation such as uneven.
Due to water fender 1 being provided with grooved hole 2, bolt 4 can not cover through hole completely, so in use cooling water can flow out from grooved hole 2, fall on steel band, in order to prevent leaking, described water fender 1 is also provided with pressing plate 5, and described pressing plate 5 fixedly abuts in the upper surface of water fender 1 by the bolt 4 installing water fender 1.Pressing plate 5 will have enough width, and when ensureing that bolt 4 is positioned at the optional position in grooved hole 2, pressing plate 5 can cover the grooved hole 2 on water fender 1 completely, makes water fender 1 play best dash effect.
Upper surface and the lower surface of described water fender 1 front end are equipped with inclined-plane.The inclined-plane on water fender 1 top is the wearing and tearing in order to reduce between working roll and the upper baffle device for water of outlet, prevents that water fender 1 front end hardness is excessive causes damage to working roll; The inclined-plane of water fender 1 bottom is to eliminate the upper ladder between baffle device for water and frame of outlet, preventing from hitting steel accident.
The utility model structure is simple, under the dash effect prerequisite not affecting baffle device for water, simply change screw hole into grooved hole, water fender is worn and torn to a certain degree to move along grooved hole, re-start utilization, extend water fender in machine utilization rate, avoid waste of material, reduce and be produced into, there is good practicality.
