Description
Technical Field
The invention belongs to the field of H-shaped steel rolling processes, and particularly relates to a combined control hole pattern of a universal rolling mill.
Background
H-shaped steel is a novel economic building steel and has wide application in various fields. The H-shaped steel has the advantages of economic and reasonable section shape, good mechanical property, more uniform extension of each point on the section during rolling, small internal stress, large section modulus, light weight and metal saving compared with the common I-shaped steel, and can lighten the building structure by 30 to 40 percent; and because the inner sides and the outer sides of the legs are parallel, and the leg ends are right angles, the structural parts are assembled and combined, the workload of welding and riveting can be saved by 25 percent, and the device is commonly used for large buildings, bridges, ships, hoisting and transporting machinery, equipment foundations, supports, foundation piles and the like which require large bearing capacity and good section stability.
Due to numerous advantages, numerous manufacturers can produce H-shaped steel, domestic small-sized H-shaped steel is mostly arranged in a full continuous rolling mode, medium-sized H-shaped steel is mostly arranged in a half continuous rolling mode, large-sized H-shaped steel is mostly arranged in a reversible rolling mode or in a half continuous rolling mode, and the large-sized H-shaped steel is characterized by multiple rolling machine frames and large early-stage investment, so that rolling passes are effectively reduced.
When the H-shaped steel is rolled, the continuous rolling part is combined by a universal hole pattern and an edge rolling hole pattern, the universal hole pattern is used for processing a web plate and a flange of the H-shaped steel, and the edge rolling hole pattern is used for processing the end part of a flange leg. Because the processing area of the flange leg end part is very small, the great rolling force cannot be generated, the capacity of a rolling mill cannot be exerted, in the rolling process of the traditional edging process, if the flange leg end part of a product is too thin or too high, the edging mill vertically rolls and processes the flange leg end part, the flange leg end part of the rolled piece is very easy to destabilize, on one hand, the problem that the top of the rolled piece is likely to bend to generate folding or the problem that the width of the flange leg end part is uneven and the symmetry of the flange leg end part is not good is shown, on the other hand, because the web plate of the rolled piece is not in contact with the roller, the condition that the processing amount of the upper roller and the lower roller is different exists when the flange.
Disclosure of Invention
In view of the above, the present invention is directed to a combined control pass for a universal rolling mill to solve the problems of uneven leg width and poor leg symmetry caused by multiple rolling passes, long rolling time, and leg bending.
In order to achieve the purpose, the technical scheme of the invention is realized as follows:
a universal mill combined control hole pattern comprises an upper horizontal roll, a lower horizontal roll, a left vertical roll and a right vertical roll;

bosses are arranged on two sides of the left vertical roll and the right vertical roll, and notches corresponding to the roll collars are arranged on one sides, close to the H-shaped steel, of the bosses.
Furthermore, the roll collar, the upper horizontal roll and the lower horizontal roll are all integrally formed.
Further, the roller ring is of a circular structure.
Furthermore, the thickness of the roll collar is larger than that of the flange of the H-shaped steel.
Compared with the prior art, the combined control hole pattern of the universal rolling mill has the following advantages:
(1) the combined control pass of the universal rolling mill can reduce rolling passes, reduce the number of rolling mills, reduce the total reversible reciprocating times, reduce the rolling time of a single blank and improve the yield of a production line;
(2) the combined control hole pattern of the universal rolling mill can realize the on-line flexible adjustment of the thickness of the web plate and the flange of the intermediate blank and the height of the flange at any time according to the requirements of a later rolling mill;
(3) in the rolling process, the combined control pass of the universal rolling mill can process the thicknesses of a web plate and a flange of a blank and can process the end part of a flange leg, the sizes of rolled pieces in all directions are completely controlled in the rolling process, the problems of uneven leg width and poor leg symmetry caused by leg bending are avoided, and the product quality is improved;
(4) the combined control pass of the universal rolling mill can reduce the workload of assembly workers in a roll preparation workshop and reduce the investment and consumption of rolls.
