Metal plate levelling process

Abstract

The invention discloses a metal plate levelling process which has the advantages of having simple operation and improving the flatness of a metal plate. The metal plate levelling process comprise the following steps: locally heating an uneven part of the metal plate; and then, splashing cold water to the uneven part. According to a principle of expansion on heating and contraction on cooling, through the method of heating first and then cooling, the metal plate can be conveniently leveled, the levelling time is greatly shortened, and the work efficiency is improved; and meanwhile, the flatness of the metal plate after the levelling is also improved.

Description

Technical field [0001] The invention relates to a metal plate leveling process. Background technique [0002] As we all know, the uneven metal plates are usually flattened by direct hammering. In this way, not only the leveling is troublesome and takes a long time, but the flatness of the surface of the metal plate after leveling is not high. Summary of the invention [0003] A technical problem to be solved by the present invention is to provide a metal plate leveling process that is simple to operate and can improve the flatness of the metal plate. [0004] In order to solve the above technical problems, the present invention adopts a technical solution: a metal plate leveling process, the steps of which are: locally heating the uneven part of the metal plate, and then splashing the part with cold water. [0005] The beneficial effects of the present invention are: according to the principle of thermal expansion and contraction, the metal plate can be leveled very conveniently by ...
