Abstract
The invention discloses a biased-eight-roll roll shape structure, which comprises the following parts: upper and lower bearing rolls, upper and lower working roll, upper and lower middle roll, upper and lower lateral support roll, wherein the upper and lower working roll and upper and lower lateral bearing roll are attached on the inner side of upper and lower bearing roll, the middle roll is set between working roll and lateral bearing roll, the center of working roll deviates the central line of bearing roll by 6-8% as bearing roll diameter, the roll radius and breadth of working roll, bearing roll, lateral bearing roll, middle roll adopts specific parameter.
Description
Technical field:
The present invention relates to a kind of cold-rolling mill.
Background technology:
MKW mill is the cold-rolling mill of a kind of minor diameter working roll, structure uniqueness, is actually on the four-high mill of backing roll transmission, working roll is set up the multi-roll mill of side backing roll.
From mechanism structure, MKW mill and four-high mill are basic identical, and the unique texture of MKW mill is that working roll has side backing roll system and departs from the installation of backing roll center line.Working roll obtains the supporting of upper and lower backing roll in vertical direction when rolling, obtains the support of side support system in side direction.Side backing roll and intermediate calender rolls are fixed on the side supporting roller bearing seat then with fixing bow assembling.The side force that affacts the side backing roll is to pass to the side supporting traverse by the supporting seat that concentric shafts is arranged with it, has so just guaranteed that roller system of rolling mill has enough big rigidity.When side backing roll and backing roll are worked under contact condition, can also be by intermediate calender rolls to the working roll carry-over moment, play to increase and depress and reduce the effect of skidding between roller.In addition, working roll departs from that the backing roll center is installed and working roll is embraced the neck device and can be guaranteed that working roll all has reliable stability in reversible and high-speed rolling.Since used minor diameter working roll and roll forming adjusting device, so MKW mill has some characteristic of four rollers and multi-roll mill concurrently on production technology, as:
1, MKW mill is the backing roll transmission, working roll departs from the backing roll center line and installs, like this, the minimizing of work roll diameter neither is subjected to the restriction of moment of torsion, also be not subjected to the influence of horizontal curvature, therefore, this operation roll of mill diameter can be very little, generally being about 1/2nd of four-high mill work roll diameter of the same type, only is the 15%-20% of backing roll diameter.Like this, MKW mill just can satisfy the requirement of rolling thin and rolling difficult modified product as multi-roll mill, and it is relatively simple for structure, and is similar to four-high mill, but draught pressure has only four-high mill half.
2, as multi-roll mill, MKW mill has the bigger roll system structure of rigidity and roll forming structure and roll forming adjusting device, total bouncing value is little, can regulate work roll crown at any time again in the operation of rolling, thereby can shut out the less and straight band steel of plate shape of thickness deviation.
3, the independent transmission of backing roll allows to use the bigger working roll of the roller poor scope in footpath, and working roll supports simple, and roll change is more convenient, and the roller consumption is few.
4, the roll gap frictional dissipation is little.
Though this kind MKW mill has above-mentioned lot of advantages, but, if the roller of working roll, backing roll, side bearing roller, intermediate calender rolls footpath, roller is wide and working roll depart from the backing roll center line select improper, can directly influence the operate as normal of MKW mill, as the generation appearance of unsettled phenomenon such as beat.
Summary of the invention:
Goal of the invention of the present invention can not produce the Eight slanting rollers shape structure of the MKW mill of wild effects such as beating when being to provide a kind of rolled plate.
The present invention realizes like this, comprise backing roll up and down, be positioned at the upper working rolls and lower working rolls between backing roll up and down, intermediate calender rolls up and down, the upper and lower sides backing roll, upper working rolls and lower working rolls, the upper and lower sides backing roll abuts against backing roll inboard up and down, intermediate calender rolls is positioned between working roll and side bearing roller and with them and abuts against, the working roll center is toward the center line of side backing roll one lateral deviation from backing roll, its special feature is that the working roll center is the 6%-8% of backing roll diameter toward side backing roll one lateral deviation from the side-play amount of the center line of backing roll, working roll, backing roll, the side bearing roller, the roller footpath of intermediate calender rolls, roller is wide to be: ф 350 serial working rolls, backing roll, the side bearing roller, the roller footpath of intermediate calender rolls, roller is wide
