Drawings
Fig. 1 is a schematic view of a coiling apparatus for HiB steel in the present invention.
Detailed Description
The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1, the coiling device for HiB steel in the utility model comprises an impurity removing device and a bending device; the impurity removing device comprises pre-cleaning roller 1 groups, hairbrush roller 2 groups, scraping blades 3 and leveling roller 4 groups which are arranged on two sides of a steel plate running track, wherein the working surfaces of the pre-cleaning roller 1 groups are provided with uniformly distributed teeth, the working surfaces of the hairbrush roller 2 groups are provided with metal hairbrushes, and the end parts of the scraping blades 3 are abutted against the surface of a steel plate; the bending device comprises two upper bending rollers 5 arranged on the upper side of the steel plate running track and a lower bending roller 6 arranged on the lower side of the steel plate running track, the lower bending roller 6 is positioned between the two upper bending rollers 5, and the upper end of the lower bending roller 6 is higher than the lower ends of the two upper bending rollers 5.
The working process of the utility model is as follows:
the cooled steel plate enters an impurity removal device from the left side, the working surface of a pre-cleaning roller 1 is provided with uniformly distributed teeth, oxides on the surface of the steel plate are crushed, the oxides are separated from a steel plate matrix, then oxide slag is removed through a hairbrush roller 2 and a scraping blade 3 in sequence, and then leveling is performed through a leveling roller 4; the steel sheet behind the edulcoration device gets into the bending apparatus again, and two last bending roller 5 form class triangle-shaped structure with a lower bending roller 6, and lower bending roller 6 makes the steel sheet roof pressure make originally straight steel sheet form certain camber, later forms the coil of strip through material receiving roller 8. The utility model discloses an edulcoration device can effectively get rid of the oxide on steel sheet surface, guarantees follow-up product quality control when cold rolling process, makes the steel sheet have certain camber before the rolling through bending apparatus, reduces the bulging force of the coil of strip of final formation, avoids the phenomenon of bulk roll to take place.
