Abstract

The invention discloses a plate rolling device and method based on magnetic pulse impact modification, and relates to the rolling device and method for impact modification of a plate by using magneticpulse. The device and the method aim to solve the problems that cracks, relatively coarse grains, uneven work hardening and poor plasticity are prone to generating in an existing rolling plate. The plate rolling device comprises an impact die, a magnetic pulse impact unit and heating devices; the impact die comprises an upper mold, a lower mold and a guide device; the upper mold and the lower mold are correspondingly arranged up and down, and the guide device is connected between the upper mold and the lower mold; the magnetic pulse impact unit comprises at least one impact drive device and one impact plate; at least one impact drive device is arranged in the upper mold, and the impact drive device can impact or reset relative to the upper mold in the lower mold direction; the bottoms ofthe impact drive devices are fixed to the top surface of an impact plate; and the heating devices are distributed in the lower mold.

Description

technical field [0001] The invention relates to a rolling device and method, in particular to a rolling device and method for performing impact modification on a plate by using a magnetic pulse. Background technique [0002] The current rolling process is to prepare plates by hot and warm rolling ingots on rolling mills, sometimes also by cold rolling at the end. After the plate is heated to the hot rolling temperature, the potential slip system is activated, the plasticity of the alloy is improved, and multi-pass rolling is carried out to ensure that the rolled piece is always within the hot rolling range. [0003] However, the heating temperature of the plate is not easy to be uniform during hot rolling, which is inconvenient for industrial production; the cold rolling process can improve the mechanical properties of the plate and the quality of the rolled piece, but it is easy to crack the plate. Moreover, although the existing rolling process can refine the structure an...
