Description

Technical Field

[0001] The invention relates to the field of nonferrous metals, and in particular to a production method of a T-shaped alloy profile. Background Art

[0002] T-profiles are named because their cross section is the same as the English letter "T". There are two types of T-profiles: 1. T-profiles are formed by longitudinally dividing H-profiles, which have the advantages of strong bending resistance, simple construction, cost saving and light structure weight; 2. T-profiles are formed by hot rolling in one step, which are mainly used in machinery, special equipment and ships.

[0003] Traditional T-profile production is to make a profile of a specific shape by extruding or welding metal billets. Depending on the shape, the corresponding processing method will also be different. For the preparation process of T-profile alloy profiles, the traditional production method is to use an extruder for extrusion molding.

[0004] In the related technology, extrusion molding is performed by using an extruder. The extruded profile has extremely high requirements on the power, load pressure, and hole type mold of the extrusion equipment. In addition, the metal fluidity is poor after extrusion, and the finished product is twisted. The thickness margin needs to be increased to about 30%, and the subsequent processing to the finished product is extremely difficult. Currently, the length of a single T-shaped profile that can be produced is only 3-4 meters, and the yield rate of the finished product is less than 50%, which is extremely wasteful. Therefore, the profiles produced by the existing T-shaped profile production method cannot meet the market demand for profiles.

[0005] Therefore, it is necessary to provide a production method of a T-shaped alloy profile to solve the above technical problems. Summary of the invention

[0006] The invention provides a method for producing a T-shaped alloy profile, which solves the problems that the production efficiency of the T-shaped alloy profile is low and the extrusion method easily causes distortion and the material performance does not meet the standards.
