Abstract
The utility model discloses a rough rolling edger roll of a plate and strip mill, which comprises an outer roll diameter, wherein the outer roll diameter is connected with an outer roll collar through a conical surface, a working surface is arranged between the outer roll collar and an inner roll collar, the inner side of the inner roll collar is connected with the inner roll diameter through the conical surface, and the inner roll diameter is connected with a roll head; the working surface is an inclined surface, and the inclination angle is 3-6 degrees. The utility model has the advantages that: the contour curve of the vertical roll is processed into an inclined plane with a certain taper by using a numerical control lathe, the taper is set according to the side turning amount of the plate blank, and the defects of dog bones and warping caused by large width reduction amount of the plate blank are well overcome. The yield is improved, the product defect rate is reduced, and the comprehensive benefits of enterprises are improved.
Description
Technical Field
The utility model relates to the field of metallurgical machinery, a edger roll specifically says so.
Background
The hot strip mill is suitable for the hot charging process of continuous casting slabs, simplifies the width series of the continuous casting slabs, improves the production capacity of a continuous casting machine, and sets a powerful vertical roll mill at the first rough rolling stage of the hot continuous mill, so that the maximum side pressure of a single pass can reach 120-150 mm.
The roll profile of the rough rolling vertical roll is usually a flat roll, the vertical roll realizes great width reduction, and simultaneously the head and the tail of the plate blank are easy to generate dog bone shapes, the occurrence of the dog bone-shaped plate blank causes the reduction of the yield, in addition, due to the realization of great side pressure, the side turning amount of the plate blank is increased, the edge of the finished product strip steel is easy to generate the warping defect, the product degradation is caused, and the production cost is increased.
Disclosure of Invention
In order to solve the technical problem, the utility model aims at providing a vertical roll, concrete technical scheme is as follows:
a rough rolling vertical roll of a plate and strip rolling mill comprises an outer roll diameter, wherein the outer roll diameter is connected with an outer roll ring through a conical surface, a working surface is arranged between the outer roll ring and an inner roll ring, the inner side of the inner roll ring is connected with an inner roll diameter through the conical surface, and the inner roll diameter is connected with a roll head; the working surface is an inclined surface, and the inclination angle is 3-6 degrees.
The inner side of the outer roll collar is provided with a boss.
The utility model has the advantages that: the contour curve of the vertical roll is processed into an inclined plane with a certain taper by using a numerical control lathe, the taper is set according to the side turning amount of the plate blank, and the defects of dog bones and warping caused by large width reduction amount of the plate blank are well overcome. The yield is improved, the product defect rate is reduced, and the comprehensive benefits of enterprises are improved.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The utility model comprises an outer roll diameter 7, the outer roll diameter 7 is connected with an outer roll collar 2 through a first conical surface 8, a working surface 4 is arranged between the outer roll collar 2 and an inner roll collar 1, the inner side of the inner roll collar 1 is connected with an inner roll diameter 5 through a second conical surface 9, and the inner roll diameter 5 is connected with a roll head 6; the working surface 4 is an inclined surface, and the inclination angle a is 3-6 degrees. In order to facilitate positioning and feeding, the inner side of the outer roll ring is provided with a boss 3.
The utility model discloses utilize numerical control lathe to process into the profile curve of edger roll and have certain tapered inclined plane, according to what of the slab volume of turning on one's side set for tapered size, better solution the slab reduce the dog bone that the volume produced greatly and stick up the skin defect, improved the lumber recovery, reduced the product defect rate, improved the comprehensive benefits of enterprise.
