Problems solved by technology

[0005] The present invention can solve the existing defects such as web eccentricity and flange warping that usually exist in the existing profile after rolling, and the existing finishing process cannot straighten the profile, resulting in the repair effect of the profile after finishing Poor, there are still a lot of defects in the profile, and when the existing equipment straightens the profile, the straightening effect is poor, and the end face of the profile is prone to deformation. At the same time, when the profile is straightened with different sizes, it needs to be replaced. The rollers cooperate with it, resulting in low working efficiency of the profile and other problems

Embodiment Construction

[0034] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0035] Such as Figure 1 to Figure 4 Shown, a kind of post-rolling finishing process of section bar comprises the following steps:

[0036] S1. Billet heating: manually send the steel billet to the inside of the furnace loading roller table for heating;

[0037] S2, billet rolling: the billet heated in step S1 is rolled into a section bar with an "I"-shaped structure through a rolling mill;

[0038] S3, lowering the temperature and cooling: placing the profile rolled in step S2 on a cooling bed for cooling;

[0039] S4, surface cleaning: manually remove impurities such as iron filings and iron oxide scales remaining on the surface of the profile in step S3;

[0040] S5. Roller straightening: put the profile cleaned in step S4 into the rolling dev...

Abstract

The invention relates to a finishing process for sectional material rolling. A mounting frame, a housing, roller pressing devices and a correcting device are involved. The housing is mounted at the upper end of the mounting frame, the cross section of the housing is of a rectangular structure, the roller pressing devices are symmetrically arranged inside the housing, the roller pressing devices are mounted on the upper side and the lower side inside the housing correspondingly, and the correcting devices are symmetrically arranged inside the housing. According to the finishing process for sectional material rolling, the problem that an existing sectional material after rolling has usually the defects of web eccentricity, wing edge warping and the like is solved, the sectional material is poor in repairing effect, and a large amount of defects exist in the sectional material; in addition, when the sectional material is straightened by the existing equipment, the correcting effect is poor, and the end surface of the sectional material is easily deformed; and meanwhile, when the sectional materials with different sizes are straightened, the problems that the working efficiency of thesectional material is low due to the fact that the corresponding roller wheels are matched with the sectional material are solved, and the like.

Description

technical field [0001] The invention relates to the field of profile finishing, in particular to a profile finishing process after rolling. Background technique [0002] The I-shaped profile is a long profile with an I-shaped cross section. The I-shaped profile has the advantages of wide flange, large lateral rigidity, and strong bending resistance, and the two surfaces of the flange of the I-shaped profile are parallel to each other, making connection, processing and installation easy. With the large number of I-shaped profiles used in production in my country, the existing market has more and more requirements for product specifications, and the requirements for product form and size are becoming increasingly strict. [0003] At present, the existing I-shaped profiles usually have the following defects during the finishing process of rolling: 1. After the profile is rolled, the profile usually has defects such as web eccentricity and flange warping. The process cannot st...
