Body has the roll shape method of adjustment of control panel shape, such as AS-U convexity regulating mechanism, but with existing Plain four high rolling mill, six rollers
Milling train compares, and Sendzimir mill work roll diameter is smaller, and flexible deformation is more complicated, and AS-U convexity adjustment amount pair
Work roll shape influence it is smaller, micro adjustment can only be carried out to roll gap shape, thus the adjustment of AS-U convexity in the middle part of band and
The extensional of edge has an impact, and improves to more complex flatness defect (such as a quarter wooden dipper is bent) very little.In order to make up
The motor-driven regulating power of AS-U convexity regulating mechanism eliminates the bad plate shapes such as side wave, middle wave and rib wave, therefore to Sendzimir two
The roll shape and roll crown of ten roller reversable cold-rolling machines optimize, and obtain reliable and stable roll shape system (the i.e. original roller of roll
Type).
Meanwhile also for the roll change number of working roll and the workload of grinding roller is minimized, so selection is among first
Roller and second among loose roll on its roll shape is redesigned: upper intermediate calender rolls are designed as double-cone roller, this be mainly because
Acutely decline in correspondence close to the amount of deflection at strip edge for working roll, is thinned to eliminate strip side portion resulting from,
Upper intermediate calender rolls both ends devise taper, reduce effectively rolling region, and first intermediate roll not only has very titanium band edge extensional
Big effect, extending on middle part also has certain influence, is rolled using double-cone roller, can effectively control Strip Shape, mitigate four/
One wooden dipper is bent.Lower intermediate calender rolls are designed to convexity roller, main cause are as follows: the convexity of lower intermediate calender rolls adjusts the influence to working roll amount of deflection
It is the several times that AS-U convexity is adjusted, influence of the lower intermediate roll crown adjustment compared to other regulative modes to work roll shape is more straight
It is connected to effect, it can more directly effective control band foil strip shape quality.Upper loose roll and lower loose roll are designed to the master of convexity roller
Acting on the improvement for changing opposite side wave, middle wave titanium flatness defect simple in this way for the convexity of upper loose roll and lower loose roll has
Effect, and the abrasion of the following group first intermediate roll can be reduced, and experiment proves that, the both ends of upper intermediate calender rolls (double-cone roller)
The long L=30mm~40mm of cone, taper tan α=0.037%~0.084%, wherein α be the double-cone roller cone angle when, under
The middle part outer diameter of intermediate calender rolls is 0.01mm~0.03mm bigger than the outer diameter at the both ends of lower intermediate calender rolls, and the middle part outer diameter of upper loose roll is than upper
When the shape and size all the same of the big 0.02mm~0.05mm of the outer diameter at the both ends of loose roll, lower loose roll and upper loose roll, roll
The micron order titanium foil defect of system is minimum, and plate shape is more smooth, and titanium foil is best in quality.
3, the present invention can be effectively improved plate shape, and band is resolved in reduction, accurate to control foil thickness, improve yield rate and product
Quality.Micron order titanium foil thickness deviation ± 0.0005mm prepared by the present invention, only ± the 5.5% of product thickness~±
7.5%, dimensional accuracy is better than the high-precision requirement (± 10%) of national standard GB/T 3622-2012 (titanium or titanium alloy is with foil), and
