Description

Device for replacing temper mill
Technical Field
The utility model belongs to the technical field of level and smooth equipment, especially, relate to a replace levelling machine's device.
Background
And after annealing, the finished strip coil needs to be subjected to plate shape correction due to stress release and poor plate shape. Strip coils with the thickness of less than or equal to 2.0mm can be subjected to plate shape correction through a stretch bending straightening machine, and strip coils with the thickness of more than 2.0mm need to be subjected to plate shape correction through a flattening machine; however, the temper mill has high cost and low utilization rate, and if the strip shape of the strip coil with the thickness of more than 2.0mm cannot be straightened, the strip coil flatness cannot meet the requirement, the rework rate is high, and the production cost is increased.
Disclosure of Invention
The utility model discloses just to the defect that prior art exists, provide a device that replaces levelling machine.
In order to achieve the purpose, the utility model adopts the following technical proposal that the device comprises a first roller set and a second roller set which are positioned on the left side and the right side of the winding belt and are arranged oppositely; the first roller set and the second roller set have the same structure and respectively comprise supporting rollers (supporting rollers) arranged from outside to inside, intermediate rollers (used for mechanical transmission) and working rollers.
The two sides of the central line of the first roller set and the second roller set are respectively provided with a crimping machine: a left crimper and a right crimper; a left tension roller is arranged between the left crimping machine and the working roller, and a right tension roller is arranged between the right crimping machine and the working roller.
Further, the supporting rollers, the middle rollers and the working rollers of the first roller group and/or the second roller group are collinear.
Further, the left crimper is positioned opposite the right crimper at the same distance from the work roll.
Further, the left tension roller is opposite to the right tension roller in position.
Further, the radius of the supporting rollers is larger than that of the middle rollers, and the radius of the middle rollers is larger than that of the working rollers.
Compared with the prior art the utility model discloses beneficial effect.
For finished product coiled belts with the thickness of more than 2.0mm, the stress release plate shape is poor after annealing, the arch height is more than 50mm, the finished product is easy to scratch when being sheared, and the plate shape can not meet the requirement of 5 mm/m. Through process optimization, utilize the utility model discloses the device levels technology, improves the arch height of coil of strip, makes the arch height reduce to below 20mm, then carries out finished product straightening, shearing, and the plate qualification rate that the plate-type straightness satisfies 5mm/m reaches more than 90%, improves the yield by a wide margin. And the cost is low.
Drawings
The present invention will be further described with reference to the accompanying drawings and the following detailed description. The scope of protection of the present invention is not limited to the following description.
Fig. 1 is a schematic view of the overall structure of the present invention.
Fig. 2 is a schematic view after flattening.
In the figure, 1 is a support roller, 2 is an intermediate roller, 3 is a work roller, 4 is a left tension roller, 5 is a left crimper, 6 is a right crimper, and 7 is a right tension roller.
Detailed Description
As shown in fig. 1, in the first embodiment, the present invention includes a first roller set and a second roller set which are located on the left and right sides of the winding belt and are opposite to each other; the first roller set and the second roller set have the same structure and respectively comprise supporting rollers 1 (supporting rollers) arranged from outside to inside, intermediate rollers 2 (used for mechanical transmission) and working rollers. The back-up rolls are used to support the intermediate rolls 2 and transmit forces through the intermediate rolls 2 to the work rolls, which are used to contact the product to be rolled. The arrangement of the supporting roll can reduce the diameter of the working roll and enhance the rigidity of the working roll. Since the contact stress in the contact area is a harmful bending moment which increases the roll deflection, the harmful contact area is the contact area between the work roll and the back-up roll which is larger than the width of the rolled strip. The additional design of the intermediate roll 2 eliminates the detrimental contact between the rolls by virtue of the intermediate roll 2 pulling, thereby greatly reducing the deflection of the work rolls.
The two sides of the central line of the first roller set and the second roller set are respectively provided with a crimping machine: a left crimper 5 and a right crimper 6; a left tension roller 4 is arranged between the left crimping machine 5 and the working roller, and a right tension roller 7 is arranged between the right crimping machine 6 and the working roller.
And the support rollers 1, the middle rollers 2 and the working rollers of the first roller set and/or the second roller set are collinear. The left crimping machine 5 is opposite to the right crimping machine 6, and is equidistant from the working rolls. The left tension roller 4 is opposite to the right tension roller 7. The radius of the supporting roll is larger than that of the middle roll 2, and the radius of the middle roll 2 is larger than that of the working roll. The utility model discloses a roller footpath is 400 supplyes 440mm, and the accessible is controlled rolling force and is adjusted the product reduction rate.
The left tension roller 4 and the right tension roller 7 are symmetrical in position, and the left crimping machine 5 and the right crimping machine 6 are symmetrical in position. The utility model discloses replace the device of levelling machine to improve the arch height of roll coil of strip, make arch height reduce to below 20mm, then carry out the finished product aligning, cut, the plate qualification rate that the plate-type straightness satisfies 5mm/m reaches more than 90%, improves the yield by a wide margin.
In the second specific embodiment, the existing six-roller cold rolling mill can be used to replace a temper mill, and under the condition of no temper mill, a 1780 six-roller reversible cold rolling mill temper rolling process is adopted for a coil with the thickness of more than 2.5mm according to the field equipment condition. The specific process is as follows, as shown in fig. 2.
Elongation percentage: the finished product rolling process reserves a processing rate of 1.5-2.0%, the elongation is too small, the plate shape correction is not facilitated, the elongation is too large, the product performance is improved and enhanced, and the performance does not meet the requirements.
Unit tension: 0.15 KN/mm2, the high tension mainly aims to reduce the fiber size difference in the plate surface, thereby improving the plate shape straightness.
It should be understood that the above detailed description of the present invention is only for illustrating the present invention and is not limited by the technical solutions described in the embodiments of the present invention, and those skilled in the art should understand that the present invention can still be modified or equivalently replaced to achieve the same technical effects; as long as the use requirement is satisfied, the utility model is within the protection scope.
