Adopt the backing roll up and down (1,1 ') of above-mentioned parameter, the intermediate calender rolls up and down (6,6 '), the intermediate calender rolls up and down (3,3 ') on right side, the upper and lower sides in left side in backing roll (1,1 '), upper working rolls and lower working rolls (2,2 '), left side prop up roller (4,4 ') up and down; The upper and lower sides on right side prop up roller (5,5 ') roller footpath, roller is wide and the upper working rolls and lower working rolls line of centres props up roller (4,4 ') lateral deviation toward the upper and lower sides in left side and is 1%～2% of backing roll diameter up and down from the side-play amount of the line of centres of backing roll up and down, upper working rolls and lower working rolls departs from up and down, and the side-play amount of the center line of backing roll is well cooperated with diameter, the width of each roller, under common process conditions, the rolling of steel plate can be stably carried out, particularly rolling steel-sheet requirement can be satisfied well.Better than multi-roll mills such as four roller machines of same train, MKW mill stability, upper working rolls and lower working rolls roller footpath is little, and roll-force is little, and the back lining bearing long service life is made, production cost is low, and processing of roller system and installation accuracy easily realize easy accessibility.
Star-like 12 rollers of the present invention are the new structure cold-rolling mills in a kind of little working roll roller footpath, are actually on the four-high mill of backing roll transmission up and down the multi-roll mill that the upper and lower sides that upper working rolls and lower working rolls is set up left and right sides props up roller.
On structure, star-like twelve high mill and four-high mill are basic identical, and the unique texture of star-like twelve high mill is that upper and lower sides that upper working rolls and lower working rolls has a left and right sides props up roller and departs from up and down the backing roll center line and install.Upper working rolls and lower working rolls obtains the supporting of backing roll up and down in vertical direction when rolling, obtains the support of side support system in side direction.The upper and lower sides of left and right side props up the intermediate calender rolls up and down of roller and left and right sides and assembles with fixing bow, and the upper and lower sides that is fixed on left and right side then props up on the roll bearing seat.The side force that the upper and lower sides that affacts left and right side props up roller is to pass to the side supporting traverse by the supporting seat that concentric shafts is arranged with it, and roller system of rolling mill has enough big rigidity in so just guaranteeing.When the side in left side was propped up roller and backing roll is worked under contact condition up and down, intermediate calender rolls up and down that can also be by left side and right side is the working roll carry-over moment up and down, plays the effect that increases pressure and reduce to skid between roller.In addition, the right side of installation of backing roll center and upper working rolls and lower working rolls was supported and has been guaranteed that upper working rolls and lower working rolls all has reliable stability in reversible and high-speed rolling about upper working rolls and lower working rolls departed from; And back lining bearing is stressed little, and extend service life; Upper working rolls and lower working rolls stability is better used the minor diameter upper working rolls and lower working rolls; The side on the right side of upper working rolls and lower working rolls prop up roller not with backing roll up and down near, so both guaranteed the stability of upper working rolls and lower working rolls, installation, the machining accuracy of roller easily realize, convenient disassembly, processing and use cost reduce; So star 12 rollers have some characteristic of four-high mill, MKW mill and other multi-roll mill concurrently, as:
1, MKW mill is backing roll transmission up and down, upper working rolls and lower working rolls departs from backing roll center line installation up and down, like this, the minimizing of upper working rolls and lower working rolls diameter neither is subjected to the restriction of moment of torsion, also be not subjected to the influence of horizontal curvature, therefore, this milling train upper working rolls and lower working rolls diameter can be very little, generally be about 1/2nd of four-high mill upper working rolls and lower working rolls diameter of the same type, only be up and down the backing roll diameter 15%～20%.Like this, MKW mill just can satisfy the requirement of rolling thin and rolling difficult modified product, 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, have bigger roll system structure of rigidity and roll forming structure as 12 rollers and 20 rollers, total bouncing value is little, has and can regulate the upper working rolls and lower working rolls convexity at any time 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 up and down allows to use the bigger upper working rolls and lower working rolls of the roller poor scope in footpath, and upper working rolls and lower working rolls supports simple, and roll change is more convenient, and the roller consumption is few.
4, the roll gap frictional dissipation is little.
