Electric shock regulation and control method for metal construction interface

Abstract

The invention discloses an electric shock regulation and control method for a metal construction interface. The electric shock regulation and control method comprises the following steps of S1, preparing metal elements, reasonably designing the number of the elements, and controlling the surface state of the elements; S2, combining the metal elements, conducting vacuum seal welding along the outer contour of the connecting face, and obtaining a seal welding metal blank; S3, enabling the seal welding metal blank to be subjected to electric shock treatment, reasonably designing the current density and the number of electric pulses, and controlling the temperature of the metal blank in the electric shock treatment process; and S4, conducting high-temperature large deformation on the metal blank subjected to the electric shock treatment, and reasonably designing thermal deformation parameters including the deformation amount and the deformation temperature. According to the electric shock regulation and control method, the electric shock pretreatment is carried out on the metal construction blank after the seal welding and before the thermal deformation, the seal welding interface state is optimized, thermal deformation interface bonding is promoted, and therefore the mechanical property of a metal component is further improved.

Description

technical field [0001] The invention belongs to the technical field of metal heat treatment, and in particular relates to an electric shock control method for a metal construction interface. Background technique [0002] Metal components have important applications in aviation, aerospace, wind power, nuclear power, construction machinery and other fields. Due to harsh service conditions, they require high mechanical properties. At present, such large metal components are mostly manufactured by forging large ingots. However, the larger the ingot size, the more serious casting defects such as segregation and holes, and the more difficult it is to guarantee the quality of large forgings after forging. Metal forming is a new process for obtaining homogeneous large forgings by vacuum building and sealing multiple high-quality small ingots, and then undergoing high temperature and large deformation. How to ensure seamless interface connection is a difficult problem that those skil...
