Further be that the intermediate roller device of this vertical miller comprises at least two intermediate calender rolls that be arranged in parallel.
Further be that the roller-way center line of adjacent two intermediate calender rolls is symmetricly set on the both sides of rolling centerline.
Further be that the driving end of each intermediate calender rolls is in transmission connection with a reducing motor respectively.
As preferably, described reducing motor all adopts the intersecting axle driving decelerating electric machine.
Further be that adjacent two intersecting axle driving decelerating electric machines are separately positioned on the both sides of rolling centerline.
Further be that the roller-way periphery of described intermediate calender rolls is coated with protective cover plate.
Further be that the below of described protective cover plate is laid with thermal insulation layer.
Further be that the intermediate roller device of this vertical miller also comprises the cooling device that at least one is sprayed water and cool off intermediate calender rolls.
The beneficial effects of the utility model are: rotating driving device is used to drive the intermediate calender rolls active rotation, drive the slab motion by frictional force during the intermediate calender rolls rotation, therefore be the length of convenient slab short or change steel after width shorter, be subjected to the drive of intermediate calender rolls, still can pass through vertical miller normally, make vertical miller can mill length short slab, thereby enlarge the production capacity of rolling line

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Intermediate roller device as the vertical miller of Fig. 1～shown in Figure 3 comprises intermediate calender rolls 2, and described intermediate calender rolls 2 is connected with rotating driving device.Rotating driving device is used to drive intermediate calender rolls 2 active rotation, drive the slab motion by frictional force during intermediate calender rolls 2 rotations, therefore be the length of convenient slab short or change steel after width shorter, be subjected to the drive of intermediate calender rolls 2, still can pass through vertical miller normally, make vertical miller can mill length short slab, thereby enlarge the production capacity of rolling line.
Usually, the intermediate roller device of the vertical miller on the Heavy Plate Production line comprises at least two intermediate calender rolls that be arranged in parallel 2, to guarantee the bearing capacity to slab.Therefore, in order to make at least two intermediate calender rolls 2 frictional force can be applied to more uniformly the surface of slab, and reduce to increase the influence of opposite roller milling train opening degree after the transmission, as Fig. 1, the roller-way center line of adjacent two intermediate calender rolls 2 is symmetricly set on the both sides of rolling centerline 9.Like this, realize that adjacent two intermediate calender rolls 2 along roller-way centerline direction interlaced arrangement up and down, are convenient to drive slab.
As Fig. 1～Fig. 3, described rotating driving device preferably adopts reducing motor, and this design is advantages of simple more.Therefore, the driving end of each intermediate calender rolls 2 is in transmission connection with a reducing motor respectively in Fig. 1～Fig. 3.Certainly, rotating driving device also can adopt other structures, such as by a motor by distributing means for power supply with power distribution to each intermediate calender rolls 2.
As Fig. 1～Fig. 3, in order to make whole intermediate roller device structure more compact, reduce because of the influence of rotating driving device opposite roller milling train opening degree is set, described reducing motor all adopts intersecting axle driving decelerating electric machine 1.As Fig. 1～Fig. 3, because the power output shaft of intersecting axle driving decelerating electric machine 1 is vertical mutually with electric machine rotational axis, the main part of intersecting axle driving decelerating electric machine 1 is arranged on the below of each intermediate calender rolls 2, therefore makes the lateral dimension of whole intermediate roller device greatly less, guarantees structural compactedness.As Fig. 2, intersecting axle driving decelerating electric machine 1 puts together on the bearing block of intermediate calender rolls 2 by the end face flange with bolt, and the inner spline housing by its output connects with intermediate calender rolls 2 driving end splined shaft suits, and the moment of torsion of intersecting axle driving decelerating electric machine 1 generation is delivered on the intermediate calender rolls 2.
As Fig. 1, few influenced for the opening degree that guarantees vertical miller, adjacent two intersecting axle driving decelerating electric machines 1 are separately positioned on the both sides of rolling centerline 9.Because the roller-way center line of adjacent two intermediate calender rolls 2 is symmetricly set on the both sides of rolling centerline 9, therefore accordingly adjacent two intersecting axle driving decelerating electric machines 1 are separately positioned on the both sides of rolling centerline 9, reduce the lateral dimension of whole intermediate roller device, guarantee that the opening degree of vertical miller is few influenced.
As Fig. 1～Fig. 3, pierce equipment for preventing slab, the bearing block and the intersecting axle driving decelerating electric machine of protection rotating driving device and intermediate calender rolls 2, the roller-way periphery of described intermediate calender rolls 2 is coated with protective cover plate 3.As Fig. 1～Fig. 3, the below of protective cover plate 3 is laid with thermal insulation layer 6, plays thermal insulation protection.Thermal insulation layer 6 can adopt effect of heat insulation asbestos board preferably.
In addition, as Fig. 3, for intermediate calender rolls 2 is cooled off, the intermediate roller device of this vertical miller comprises that also at least one is used for the cooling device that intermediate calender rolls 2 is sprayed water and cooled off.Cooling device described in Fig. 3 comprises the cooling water pipe 8 that is arranged on intermediate calender rolls 2 belows, and the spout of cooling water pipe 8 is upwards aimed at intermediate calender rolls 2, and cooling water from certain pressures to cooling water pipe 8 that import sprays cooling to intermediate calender rolls 2.
