Abstract
The utility model discloses a tandem mill, in particular to a supporting seat of a tandem mill bottom roll, which comprises a seat body (1) and a bearing seat (3) of a bottom roll (2) which is fixed on the upper portion of the seat body (1) through flanges, wherein the supporting seat is characterized in that the top portion of the seat body (1) is provided with a water-retaining plate (4). Through the arrangement of the water-retaining plate (4), cooling water is reinforced to discharge from a gap between the lateral end face and the inside face of the seat body (1) along the bottom roll (2), the lateral cooling water is avoided from operating to externally flow, the cooling effect of rolls is strengthened, and the on-site environment is improved. The cooling water needed under the same cooling amount is less, thereby saving resources and power sources. The supporting seat is applicable to tandem mills in different models.
Description
Technical field
The utility model relates to a kind of tandem rolling mill, especially a kind of bearing of tandem rolling mill bottom roll.
Background technology
The bottom roll two ends of tandem rolling mill are usually respectively by the bearing of fore side, the transmission mechanism fixed support of transmission side, and the bearing of fore side comprises pedestal and is fixed on bottom roll bearing block and grinding roller bearing block on the pedestal by flange.In the operation of rolling of tandem rolling mill, for fear of roll crown variation, oxidation etc., all need to force cooling by cooling water, cooling water is discharged along between bottom roll end face and the bearing and the gap between the transmission mechanism and the cooling bottom roll.But owing to roller neck mainly plays a supportive role at fore side, so roll neck length is generally shorter.
Along with the raising of amount of rolling, the raising of rolling rhythm, in order to guarantee the cooling of roll, cooling water pressure also increases thereupon, can't satisfy the discharge of cooling water with the gap between the increase of hydraulic pressure above-mentioned roll fore side end face and the bearing, therefore at the roll fore side, a large amount of cooling waters flows out along the gap between bearing and the topping roll frame, even ejection, therefore along with the increase of hydraulic pressure, actual amount of cooling water increases progressively amplitude and reduces gradually.Because the cooling water outflow just requires further to increase hydraulic pressure in order to meet the needs of production, thereby forms vicious circle, and causes serious resource, the waste of the energy.
Because the cooling water outflow causes the cooling effect poor controllability, so the roll inhomogeneous cooling, the roll oxide-film comes off, iron scale is pressed into thereby cause; The coarse injustice of roll surface after the roll oxide-film comes off scratches slab easily, slab scratches the interior same secondary oxidation iron sheet that forms rapidly as thin as a wafer of groove that the back forms, behind the mm finishing mill unit rolling deformation, be pressed into, therefore reach batch abnormal quality that easily causes steel band, therefore seriously limited the raising of mill production.Simultaneously, cooling water outbound flows in a large number, also has a strong impact on site environment, withdrawing roll dolly chain is got rusty frequently change, and has increased maintenance cost.
The utility model content
In order to overcome existing deficiency, technical problem to be solved in the utility model provides a kind of bearing that can avoid the tandem rolling mill bottom roll of fore side cooling water outflow.
The technical scheme that its technical problem that solves the utility model adopts is: the bearing of tandem rolling mill bottom roll, comprise that pedestal reaches the bearing block that is fixed on the bottom roll on pedestal top by flange, and described pedestal top is provided with water fender.
The beneficial effects of the utility model are: by the setting of water fender, can avoid the outflow of fore side cooling water, strengthen the cooling effect of roll, the roll oxide-film deciduous iron scale of having stopped to cause because of the roll inhomogeneous cooling is pressed into; Improved site environment; Needed cooling water is few under identical amount of cooling water, has saved the resource and the energy.
Description of drawings
Fig. 1 is that master of the present utility model looks;
Fig. 2 is the partial enlarged drawing in Figure 1A zone.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1 and Figure 2, the bearing of tandem rolling mill bottom roll of the present utility model comprises that pedestal 1 reaches the bearing block 3 that is fixed on the bottom roll 2 on pedestal 1 top by flange, and described pedestal 1 top is provided with water fender 4.
Setting by water fender 4, forced cooling water is discharged along the gap between bottom roll 2 fore side end faces and pedestal 1 medial surface, can avoid the outflow of fore side cooling water, strengthen the cooling effect of roll, the roll oxide-film deciduous iron scale of having stopped to cause because of the roll inhomogeneous cooling is pressed into; Improved site environment; Needed cooling water is few under identical amount of cooling water, has saved the resource and the energy.
The width of water fender 4 and height are determined according to concrete assembly space and working roll size.For in dimension of roller, when drafts changes, can make the size of water fender 4 and assembly space and the working roll size after the variation adapt by changing water fender 4.Described water fender 4 is by being bolted to the demountable structure on the pedestal 1.
Concrete, in order to simplify making, described water fender 4 bottoms are provided with the arc groove that adapts with bearing block 3 shapes, and described water fender 4 is fixed by the fastening bolt of bearing block 3 flanges; The medial surface of described water fender 4 and pedestal 1 lateral surface are close to.
Above-mentioned inboard is promptly near a side of roll, and the outside is promptly away from a side of roll.
Claims (3)
1. the bearing of tandem rolling mill bottom roll comprises that pedestal (1) reaches the bearing block (3) that is fixed on the bottom roll (2) on pedestal (1) top by flange, and it is characterized in that: described pedestal (1) top is provided with water fender (4).
2. the bearing of tandem rolling mill bottom roll as claimed in claim 1 is characterized in that: described water fender (4) is by being bolted to the demountable structure on the pedestal (1).
3. the bearing of tandem rolling mill bottom roll as claimed in claim 2 is characterized in that: described water fender (4) bottom is provided with the arc groove that adapts with bearing block (3) shape, and described water fender (4) is fixed by the fastening bolt of bearing block (3) flange; The medial surface of described water fender (4) and pedestal (1) lateral surface are close to.
