Roller is that compensation arrangement 1 is by mechanical ladder block, tapered wedges, Crown control hydraulic cylinder and sensor Deng composition; Backing roll bascule 4 is made up of backing roll balance weight, hydraulic cylinder and control element etc.; Hydraulic roller-bending device 7 is made up of roller bending block, hydraulic cylinder and control element etc.; Hydraulic pressure presses micromatic setting 8 by pressing hydraulic cylinder and sensor forms; Move axially device 11 by support, mobile hydraulic cylinder with Reach compositions such as detecting control element; Cooling and lubricating device 12 is made up of support, spray beam, cylinder etc.; Moving axially locking device 14 is made up of hydraulic cylinder, locking pin, support and sensor.
The specific embodiment
The utility model is described in further detail according to accompanying drawing 1-3:
The roller system that roll (backing roll 2, intermediate calender rolls 5, working roll 6) is formed is installed in the vertical plane, and supports intermediate calender rolls 5, intermediate calender rolls 5 support works rollers 6 by backing roll 2; Simultaneously each is used to the working roll 6 accepting to drive by one between two intermediate calender rolls 5, and intermediate calender rolls 5 can move along its axis.
Hydraulic roller-bending device 7 is used for the bending of working roll 6 and intermediate calender rolls 5; Backing roll bascule 4 is used for the balance of top backing up roll 2; Axial moving device 11 is used for moving axially of intermediate calender rolls 5; Axle moves the axial locking that locking device 14 is used for axial moving device 11 and intermediate calender rolls 5; Upper working rolls and lower working rolls 6 is a live-roller, the rotation of intermediate calender rolls 5 and backing roll 2 about driving respectively.
Be installed in the roller hydraulic cylinder in the hydraulic roller-bending device 7, the same moved further in the time of can realizing intermediate calender rolls 5 operate as normal.
Hydraulic pressure presses the vertical and horizontal tolerance that micromatic setting 8 is mainly used in On-line Control band steel, in the operation of rolling On-line Control is carried out in the varied in thickness of raw material, the variation of tension force and the variation of mill speed etc., the vertical and horizontal tolerance that makes the band steel after rolling is in the target control scope.Hydraulic roller-bending device 7 is mainly used in the plate shape and the horizontal tolerance of control band steel, by applying the convexity that bending roller force is adjusted intermediate calender rolls 5 at intermediate calender rolls 5 two ends, to improve the plate shape of rolled band steel.Backing roll bascule 4 is mainly used in the balance top backing up roll.Axial moving device 11 is mainly used in the strip edge portion convexity that control is caused by the rolled band steel wide variety.Roller system sews and mend and repays device 1 and be made up of mechanical ladder block, tapered wedges and sensor etc., roller system sew and mend repay device 1 be mainly used in by after the reconditioning of roll to compensate rolling height, satisfy the normal reference range of mill milling.Hydraulic axial locking device 3 is mainly used in the axial location of roll, to keep the normal duty of roll.Roll change hydraulic cylinder 10 is mainly used in and lifts intermediate calender rolls 5, is beneficial to roll change buggy and changes the interior intermediate calender rolls 5 of frame.Top working roll roll change pin 13 adopts automatic clutch, is supported on the bottom working roll, to satisfy the requirement of the paired fast roll changing of working roll.
The utility model makes this mill roll-gap setting, online roll gap fine setting, roller and balance, roll reconditioning compensation and axial locking etc. all adopt hydraulic control, its roll is stressed evenly simultaneously, do not change with the variation of roll location, thus the stability of assurance rolling mill characteristic.Thereby the vertical and horizontal dimensional accuracy of rolled products and the stability of plate shape have been improved.
During top working roll roll change automatic clutch pin operate as normal, upper working rolls and lower working rolls separates automatically, engages automatically during roll change, and top working roll is carried on the back out bottom working roll, effectively prevents roller, roll release.
Remove during roll change top working roll need the bottom working roll back of the body out all the other each rollers all can independently change roll fast.
The utlity model has following advantage:
A has improved the dimensional accuracy of cold-rolled steel strip products, and has strengthened plate shape control ability. Because Adopt hydraulic pressure to press micromatic setting so that with steel vertically and the transverse gage allowance control at the high accuracy model In enclosing. Adopt simultaneously to move axially device, so that the convexity that is caused by change width with steel can better Controlled. And then so that can be in high-precision scope to the plate shape control of rolled band steel.
B has improved the automaticity in the production process. Because the compensation of roller system, backing roll bascule, Changing rig and axial locking device all adopt hydraulic control, have realized the Automatic Control pattern, fortune Row is steady, control accuracy is high, thereby has improved the control level.
It is simple that c equipment presses mechanism. Owing to adopt hydraulic pressure to push to fast system, big stroke height only be set The precision hydraulic cylinder can be realized, characteristics of compact layout is simple in structure.
The d roller is stable and precision is high to roll control. Because bowed roller hydraulic cylinder is mobile with roll, So that the bending roller force that imposes on roll is because the change in location of roll changes, thereby roller control pair The active position of roll bearing remains unchanged, thereby the Influence from Eccentric of bending roller force breaker roll is littler, thereby Improved the stability of roller control, and the service life of having improved bearing.
The e roll change is quick, flexible, reliable and stable.Because working roll and intermediate calender rolls adopt independently roll change track respectively, and being provided with independently on last intermediate calender rolls roller bending block, fast railway promotes hydraulic cylinder, make working roll and intermediate calender rolls independently to change respectively, thereby improved the flexibility of roll change, and easy to operate.
The f top working roll is carried on the back out by bottom working roll, and the automatic clutch pin is set on bottom working roll, and the groove of slip-off preventing is set, to prevent roller, roll release.
The utility model has improved the dimensional accuracy of cold-rolled steel strip products, and has strengthened plate shape control ability; Improved the automaticity in the production process; It is simple that equipment presses mechanism, arranges compact; Roller is stable and precision is high to rolling control, and the service life of having improved bearing; Roll change is quick, flexible, reliable and stable, and easy to operate.The utility model is applicable to belt steel products such as rolling straight carbon steel, Fine Steel Casting iron, low-alloy steel and stainless steel.
