Abstract
The invention relates to a finishing mill on a hot-rolled wide strip production line and belongs to the field of steel industry. The finishing mill on the hot-rolled wide strip production line is capable of reducing the rotational inertia of working parts, has no scratches on surfaces of products and is lower in roll consumption. Two hollow rolls are mounted on a support plate of a frame, a working roll is arranged above the two hollow rolls, the space between the working roll and each of the two hollow rolls is 1.05-1.1 times of the thickness of a steel strip, a supporting roll is arranged above the working roll, and a screwdown device mounted at the upper end of the frame is arranged at the upper end of the supporting roll. The finishing mill on the hot-rolled wide strip production line is simple in manufacturing structure, convenient to replace, long in service life and convenient for technology promotion, and can be used for manufacturing according to actual field situations.
Description
Technical field
The invention belongs to the steel industry field.
Background technology
Finishing mill unit on the broad hot strip production line generally is made up of six to seven rolling mills, and the power train of every rolling mill comprises critical components compositions such as main driving motor, main motor lubricating system, main transmission control device, shaft coupling, reductor, power transmission shaft, gear pedestal.This kind equipment increase roll consumption that is in operation, and rotary inertia is big, and rolled piece and roll very easily produce friction; Cause product surface to scratch, cause some kind of production limited, equipment any one critical component in the production use damages; The capital causes whole piece to produce the stopping production of line; Rush to repair even have under the situation of spare part, length not only consuming time, and shutdown loss is huge.
Summary of the invention
The purpose of this invention is to provide a kind of rotary inertia that reduces workpiece, product surface does not have scuffing, the finishing mill on the broad hot strip production line of reduction roll consumption.
The present invention is equipped with two hollow rolls on the supporting plate of frame; Above two hollow rolls, working roll is arranged; The spacing of working roll and two hollow rolls is 1.05～1.1 times of the belt steel thickness that passes through, and the working roll top is a backing roll, and the screwdown gear that is installed on the frame upper end places the backing roll upper end.
Manufacturing structure of the present invention is simple, and it is convenient to change, and long service life all can be manufactured according to on-site actual situations, is convenient to technology popularization.Improve capacity utilization, on hot-rolled strip production line, all can use, two roll structures are unique, and rotary inertia is little, guarantees product surface quality.Can resume production at short notice, improve capacity utilization, and guarantee end product quality.Can effectively solve roll consumption, product surface scuffing problem, break through the restriction of production kind.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
The present invention is equipped with two hollow rolls 4 on the supporting plate of frame 5; Above two hollow rolls 4, working roll 3 is arranged; The spacing of working roll 3 and two hollow rolls 4 is 1.05～1.1 times of the belt steel thickness that passes through; Working roll 3 tops are backing rolls 2, and the screwdown gear 1 that is installed on frame 5 upper ends places backing roll 2 upper ends.
In conjunction with the structural drawings data of mill housing window, working roll track lifting device and bottom working roll bearing block, the running gear of design special device again takes into full account the convenience of replacing; And utilize mill roll track and roll change push-and-pull cylinder; When the needs isolated plant, utilize roll change push-and-pull cylinder to be pushed into milling train inside, after the full recovery of milling train function finishes; Utilize the push-and-pull cylinder that device is pulled out, it is subsequent use to utilize in the workshop driving to hang away.The process conditions of this device (with the direct contact portion of rolled piece) adopts two roll structures in pony roll footpath, and for further effectively reducing its rotary inertia, every pony roll adopts hollow-core construction, and roll surface carries out suitable cure process.
Pass through technical Analysis; Get rid of (being mostly accident condition) to a certain frame of hot-strip, design a special device again and directly be connected transition, suitably increase the drafts of other several rolling mills to this frame exit from accident frame inlet; Make rolled piece can pass through each rolling pass of rolling line smoothly; Adjust parameters such as milling train rotating speed, drafts between frame and frame according to existing control model again, make rolled piece output finished product as requested, guarantee that production continues to carry out.It is commonplace that this production decision is produced line in each hot rolling, can effectively improve capacity utilization, for enterprise creates considerable economic.
