Rolling method for metal thin strip difficult to deform based on laser heating

Abstract

The invention provides a rolling method for a metal thin strip difficult to deform based on laser heating. The rolling method comprises the following steps that the metal thin strip difficult to deform with a certain thickness and width is prepared; the upper and lower surfaces of the metal thin strip difficult to deform are cleaned for later use; and the metal thin strip with the upper and lower surfaces cleaned is rolled under the working condition of pulse laser heating. Compared with a traditional hot rolling process, the pulse laser heating rolling method has the advantages that technological processes can be reduced, and the energy consumption is decreased; the production efficiency is improved, and the output value of the metal thin strip difficult to deform can be improved; through the pulse laser heating rolling method, the surface temperature of the rolled piece can be accurately controlled in real time, and instant heating of the thin strip is achieved; oxidation is reduced, and the plasticity of the rolled piece in the rolling process is improved; and plastic deformation of the rolled piece is facilitated, and the quality of a finished product is improved.

Description

technical field [0001] The invention belongs to the technical field of metal material rolling, and in particular relates to a rolling method of a difficult-to-deform metal thin strip based on laser heating. Background technique [0002] Refractory metal thin strips have high deformation resistance, poor plasticity and work hardening phenomenon during normal temperature processing. Generally, it is difficult to use cold rolling method for final product rolling. However, with the increase of rolling temperature, the plastic deformation capacity of some refractory metals Significant improvement can be obtained. At present, the production of many hard-to-deform metal strips is mainly carried out by hot rolling process. However, the traditional hot-rolling process has high requirements on the production line and heating equipment, the production line equipment is expensive, and there is oxidation on the surface of the hard-to-deform metal strip during the rolling process. And ot...
