Description

Steel coil off-line leveling system

Technical Field

The utility model relates to the technical field of steel strip production, in particular to a steel coil off-line leveling system.

Background

The stainless steel strip after cold rolling can pass through the annealing and pickling process to further improve the machining performance of the steel strip and the surface quality of the steel strip, then pass through a leveling unit, the steel strip is refitted by a withdrawal and straightening unit, the shape of the steel strip is improved, downstream customers have a better flatness during splitting and splitting processing, finally the steel strip is rolled and packaged into a steel coil, and in order to prevent the surface of the steel strip from being scratched, packing paper can be laid on the steel strip during coiling, so that every layer of the steel coil passes through the interval of the packing paper, and the surface of the steel strip is protected from being scratched mutually. After the quality of some steel coil finished products is inspected, the plate-shaped quality of the steel coil finished products does not meet the quality requirement, and the steel coil finished products can become unqualified products. In order to reduce the economic loss caused by unqualified products, enterprises can repair the unqualified products through the steel coil offline leveling system, so that the unqualified products can meet the plate-shaped quality requirement of the steel coil after one-step leveling and shaping, and become qualified products.

The existing steel coil off-line leveling system has the following defects:

1. need get rid of the packing paper of laying on the steel band surface before refurbishing the steel band, the decoiler can support mechanism bearing and guide steel band horizontal transfer through the steel band after launching the steel band into the steel band with the coil of strip, levelling mechanism's entrance is equipped with blowing mechanism, blowing mechanism blows off the packing paper from levelling mechanism, avoid the packing paper to get into levelling mechanism, the staff need with the packing paper that the steel band supported in the mechanism snatch and put into the collection box, because the space of collection box is limited and the packing paper is put in a jumble way, make the packing paper volume of several coil of strip length can pile up the collection box, make the staff need frequently carry and empty the packing paper in the collection box, increase staff's extra work load. In addition, when the steel belt unreels, need artifical synchronous recovery packing paper, staff's intensity of labour is big, is not convenient for the staff and compromises other control work.

2. In the steel strip flattening process, foreign matters such as dust and wool felt fibers exist on the surface of the steel strip, and in the subsequent production process, the foreign matters on the surface of the steel strip can be adhered to the roller after contacting with the surface of the roller on the flattening mechanism. Because the equipment is always in the high-speed running process, although part of foreign matters can be taken away by the steel strip, part of the foreign matters can be adhered to the roller and continuously transferred onto the surface of the steel strip at equal intervals, so that the surface of the steel strip is flawed, and the quality of the steel strip is reduced. So need regularly clear up the roll on the levelling mechanism, but the roll subassembly of current levelling mechanism can not remove, and the staff need be shut down the back and get into the inside maintenance clearance that carries out of coil of strip off-line levelling system, because the peripheral mechanism of levelling mechanism is various, and the space is narrow and small, and the staff is difficult to develop the cleaning work, and work efficiency is low, and some blind area positions can not clear up in place even.
