Description
One, technical field
The utility model relates to a kind of device of hot-leveling of cold rolling hard attitude steel band, especially a kind of device of hot-leveling of the cold rolling hard attitude steel band that is adapted to stainless steel band and alloyed steel strip.
Two, background technology
Cold rolling hard attitude steel band all will carry out smooth and destressing to steel band in use usually, and the later stage that so just is beneficial to steel band uses, and therefore carrying out the smooth and destressing of cold rolling hard attitude steel band is handled is an important step; Existing flattening process does not generally comprise destressing to be handled, if carrying out destressing handles, common way is to carry out once putting into after smooth bell furnace earlier to carry out destressing and handle, carry out the smooth technology of secondary afterwards again, owing to be smoothly separately to carry out for twice, steel band is carrying out still having residual internal stress after stress is handled, and template is difficult to smooth fully, and this process cycle is long, cost is high.
Three, summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of this utility model provides a kind of device of hot-leveling of cold rolling hard attitude steel band, smooth better effects if, and the residual stress range of decrease is bigger.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of hot-leveling device of cold rolling hard attitude steel band includes destressing stove, first group of tension level(l)ing device and second group of tension level(l)ing device; First group of tension level(l)ing device is arranged on the porch of destressing stove, second group of tension level(l)ing device is arranged on the exit of destressing stove, the cylinder of first group of tension level(l)ing device and second group of tension level(l)ing device is set to respectively connect with independent motor, the velocity of rotation of each motor is set to inequality, and cold rolling hard attitude steel band is set to twine behind the cylinder of first group of tension level(l)ing device and is set to enter into the destressing stove and is set to twine second group of tension level(l)ing device cylinder again.
Cold rolling hard attitude steel band through the cylinder of first group of tension level(l)ing device smooth after, in entering the destressing stove, be heated to 350-650 ℃ and remove stress, the cooling back is directly smooth through the cylinder of second group of tension level(l)ing device; Because cold rolling hard attitude steel band is subjected to pass through the stretching and leveling that first, second organizes the tension level(l)ing device again behind the heat abstraction stress in the destressing stove, changed usually when for the second time smooth, the internal stress state of cold rolling hard attitude steel band, so smooth better effects if, the residual stress range of decrease is bigger.
The utility model has designed, and first group of tension level(l)ing device is set to include cylinder I, cylinder II, cylinder III and cylinder IV; The turning cylinder of cylinder I, cylinder II, cylinder III and cylinder IV is by trapezoidal arrangement.Convenient destressing in the destressing stove is handled.
The utility model has designed, and second group of tension level(l)ing device is set to include cylinder V, cylinder VI, cylinder VII and cylinder VIII; The turning cylinder of cylinder V, cylinder VI, cylinder VII and cylinder VIII is by trapezoidal arrangement.Smooth better effects if.
Four, description of drawings
Accompanying drawing is the hot-leveling schematic representation of apparatus of cold rolling hard attitude steel band.
Five, the specific embodiment
Accompanying drawing is an embodiment of the hot-leveling device of cold rolling hard attitude steel band of the present utility model, specify present embodiment in conjunction with the accompanying drawings, include destressing stove 5, cylinder I 1, cylinder II 2, cylinder III 3, cylinder IV 4, cylinder V 6, cylinder VI 7, cylinder VII 8 and cylinder VIII 9; Cylinder I 1, cylinder II 2, cylinder III 3 and cylinder IV 4 are arranged on the porch of destressing stove 5, cylinder V6, cylinder VI 7, cylinder VII 8 and cylinder VIII 9 are arranged on the exit of destressing stove 5, cylinder I 1, cylinder II 2, cylinder III 3, cylinder IV 4, cylinder V 6, cylinder VI 7, cylinder VII 8 and cylinder VIII 9 are set to respectively connect with independent motor, the velocity of rotation of each motor is set to inequality, cylinder I 1, cylinder II 2, the turning cylinder of cylinder III 3 and cylinder IV4 is by trapezoidal arrangement, cylinder V 6, cylinder VI 7, the turning cylinder of cylinder VII 8 and cylinder VIII 9 is by trapezoidal arrangement, and cold rolling hard attitude steel band is set to twine cylinder I 1, cylinder II 2, cylinder III 3 and cylinder IV 4 backs also are set to enter into destressing stove 5 and are set to twine cylinder V 6 again, cylinder VI 7, cylinder VII 8 and cylinder VIII 9.
In the present embodiment, destressing stove 5 is set to the gas shield heating furnace.
Cold rolling hard attitude steel band through cylinder I 1, the cylinder II 2 of first group of tension level(l)ing device, cylinder III 3 and cylinder IV 4 smooth after, in entering destressing stove 5, be heated to 350-650 ℃ and remove stress, suitably after the cooling through cylinder V 6, cylinder VI 7, cylinder VII 8 and the cylinder VIII 9 of second group of tension level(l)ing device.
When using this enforcement, owing to designed first group of tension level(l)ing device; Make cold rolling hard attitude steel band at first smooth, convenient destressing in destressing stove 5 is handled.Owing to designed second group of tension level(l)ing device; Make destressing process and stretching and leveling in destressing stove 5 carry out smooth better effects if simultaneously.Because having designed destressing stove 5 is set to the gas shield heating furnace; The heat tracing better effects if has been avoided the steel band oxidation.
The characteristics that the utlity model has:
1, with flattening process and the combination of destressing technology, can well eliminate the internal stress of cold-rolled strip, obtain good template (being glacing flatness).
2, the continuous destressing stove of this process using, the production efficiency height.
3, this technology has reduced production process because operation merges, and has saved the production time, has improved production efficiency, has reduced production cost.
When implementing the present embodiment process, find only through behind first, second tension level(l)ing device, the yield strength or the yield limit effect that overcome cold rolling hard attitude steel band are bad, after processing through the destressing in the destressing stove 5, not only improved significantly the smooth effect of cold rolling hard attitude steel band, and when the cold rolling hard attitude steel band residual stress behind this flattening device of process is measured, find to have decreased by 70%.
