Abstract
Disclosed is an eighteen-roller mill. Side support devices of a working roller are vertically mounted in the front and the rear of a mill stand assembly respectively, each side support device comprises a side support bearing block, a side roller and a side support roller, and advancing and retreating positions of the side support devices are controlled by servo valves and side thrust cylinders with displacement sensors. When in rolling, side support positions are set according to different process parameters, lateral deformation of the working roller due to rolling is offset, and rigidity of the working roller is enhanced. By the aid of the small-diameter working roller and a side thrust roller system, the requirement of rollers on stiffness in rolling is met, the rolling requirements of extremely thin strips can be met, and the eighteen-roller mill has the advantages that the mill is large in opening, the rollers and the strips are effectively lubricated and are high in speed, and the eighteen-roller mill is convenient in maintenance and low in manufacturing cost.
Description
Technical field
The utility model relates to a kind of roller mill, is specifically related to a kind of eighteen-high mill.
Background technology
In recent years, along with the further increase of market to the demand of flat cold-rolled sheet, and the ever-increasing situation of stainless steel, silicon plate demand, multi-roll mill is more and more favored by the user.
External Sendzimir type 18 roller mills have its advantage: the milling train rigidity is large, and the working roll footpath is less, can rolling more thin product.But its deficiency is arranged also: the milling train opening degree is little, and roller and band are lubricated relatively poor, and speed is lower; Plant maintenance is inconvenient; Equipment manufacturing cost is higher.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of eighteen-high mill, has a milling train opening degree large, and roller and band lubricate, and speed is high; Plant maintenance is convenient; The advantage that equipment manufacturing cost is low.
In order to achieve the above object, the technical scheme taked of the utility model is:
A kind of eighteen-high mill, comprise working roll 8, two working rolls 8, two intermediate calender rolls 9, two backing rolls 10, eight side backing rolls 6 and four side rollers 7 form 18 roll shapes, working roll 8 is supported by backing roll 10 by intermediate calender rolls 9, the side bracing or strutting arrangement of working roll 8 is contained in respectively rolling-mill housing and assembles 5 front and back, arranges up and down.
Described side bracing or strutting arrangement comprises side roller 7, side backing roll 6, side supporting bearing base 11, and every group of side backing roll 6 is made of two groups of back lining bearings, and side backing roll 6 is linked together by side supporting bearing base 11 with side roller 7.
The side bracing or strutting arrangement is by the position with thruster cylinder 3 and its forward-reverse of servo valve control of displacement transducer.
With comparing of external Sendzimir 18 roller mills, characteristics of the present invention are: the side bracing or strutting arrangement of working roll is contained in respectively before and after the rolling-mill housing assembling, arranges up and down the pattern that the side bracing or strutting arrangement is comprised of side roller, side backing roll, side supporting bearing base etc.; The side bracing or strutting arrangement has the position with thruster cylinder 3 and its forward-reverse of servo valve control of displacement transducer, when rolling, and the position of supporting according to different processing parameter setting side, thus offset the lateral deformation when rolling because of working roll, increase the rigidity of working roll.This pattern has the processing of being easy to, the convenient advantage of observing of milling train threading.The position probing of side roller 7 and setting are completed by high-precision displacement transducer, and pressure is by determination of pressure sensor, and position and pressure are backfeed loop.This minor diameter working roll 8 adds that the roller of thruster is mode, has both guaranteed the requirement of roll rigidity when rolling, can satisfy again the rolling needs of ultra-thin strip simultaneously.Owing to adopting this structure, lubricating condition is better, and the rolling mill speed maximum can reach per minute more than 900 meters.Adopt the eighteen-high mill of this mechanism can greatly save in equipment investment, so Technique Popularizing has a extensive future.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is two working rolls 8, two intermediate calender rolls 9,10, eight side backing rolls 6 of two backing rolls and four 18 roll shape schematic diagrames that side roller 7 forms.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
See figures.1.and.2, a kind of eighteen-high mill, comprise rolling line adjusting device 1, roll assembling 2, thruster cylinder 3, press oil cylinder 4, rack 5, side backing roll 6, side roller 7, working roll 8, intermediate calender rolls 9, backing roll 10, two working rolls 8, two intermediate calender rolls 9, two backing rolls 10, eight side backing rolls 6 and four side rollers 7 form 18 roll shapes, working roll 8 by intermediate calender rolls 9 by backing roll 10 supportings, backing roll 10 and be connected oil cylinder 4 connections, the side bracing or strutting arrangement of working roll 8 is contained in respectively rolling-mill housing and assembles 5 front and back, arranges up and down.
Described side bracing or strutting arrangement comprises side roller 7, side backing roll 6, side supporting bearing base 11, and every group of side backing roll 6 is made of two groups of back lining bearings, and side backing roll 6 is linked together by side supporting bearing base 11 with side roller 7.
The side bracing or strutting arrangement is by the position with thruster cylinder 3 and its forward-reverse of servo valve control of displacement transducer.
Rolling line adjusting device 1, roll assembling 2, thruster cylinder 3 presses oil cylinder 4 and all is assemblied in rack 5.
Operation principle of the present utility model is:
the effect of rolling line adjusting device 1 is all can keep rolling line on a horizontal level when new roller and old roller, when rolling, the side bracing or strutting arrangement is under the driving of hydraulic pressure, roll assembling 2 contacts with working roll 8, thruster is to the operating position, and the formation position closed loop is controlled under the control of computer, when rolling under the driving of depress oil cylinder 4, promote backing roll 10, intermediate calender rolls 9 and working roll 8 are to rolling position, and the position closed loop that forms depress oil cylinder 4 under the control of computer is controlled, the utlity model has larger rigidity, can produce straight carbon steel or the stainless steel of thinner thickness, the difficult-to-deformation materials such as silicon steel, and be easy to control, convenient operating maintenance, can be used in the production line of cold rolling unit.
