[0002] H-shaped steel is widely used in many fields. H-shaped steel is composed of two flange plates parallel to each other and a web perpendicular to the flange plate. According to different processing techniques, there are two types of hot-rolled H-shaped steel and welded H-shaped steel. The web of common hot-rolled H-shaped steel is flat web. The processing technology of this kind of H-shaped steel is simple, but it has the disadvantages of poor strength, large bending deformation and low bearing capacity in use.
Although welded H-beams have already appeared in the form of corrugated webs, the efficiency of welding and processing H-beams is low and cannot meet the needs of large-scale and integrated production

Embodiment Construction
[0022] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings. In order to complete the production process of this hot-rolled H-beam, a new type of roll profile is adopted on the finishing roll of the finishing mill. Corresponding curve line segment, this kind of curve line segment can be one of arc line, hyperbola, parabola, ellipse line, or one of "П" line segment, "v" line segment or "︹" line segment, Using different curves or line segments, hot-rolled H-shaped steel with different cross-sectional shapes can be obtained. When the curve is used to form the finish rolling roll mouth, the corrugated web H-shaped steel is processed. When the "П" line segment is used to form the finish rolling roll mouth , to process rectangular web H-shaped steel, when the "v" line segment is used to form the finishing roll H-shaped steel, the triangular web H-shaped steel is processed, and when the "︹" line segment is ...

Abstract
The invention discloses a hot-rolled non-flat web H-shaped steel finishing roll profile and processing technology. The H-shaped steel includes a flange plate and a non-flat web. Composition, which is characterized in that: the profile of the web finish rolling roll forms a curved line segment corresponding to each other up and down, and the curved line segment can be a line segment in a plane curve such as an arc line, a hyperbola, a parabola, and an ellipse. The beneficial effects of the present invention are: to provide a finishing roll profile of non-flat web H-shaped steel and its hot-rolling processing technology, the hot-rolled H-shaped steel processed by this method has high precision, and the resistance of flange plate and web plate is high. Strong buckling deformation ability, improved structural performance, overcomes the shortcomings of low processing efficiency in the process of welding the same type of H-shaped steel, especially suitable for mass production process, reduces production costs, and improves production efficiency.
