specific Embodiment approach 2

[0096] Specific embodiment 2, the rolling method of the plate rolling device based on the magnetic pulse impact modification of the present embodiment, the method is as follows:

[0097] Step 1. Move the upper mold upward, and place the plate to be impacted on the lower mold;

[0098] Step 2: Turn on the magnetic pulse power supply to energize the flat coil, and the flat coil generates an electromagnetic force that acts on the metal drive plate, so that the metal drive plate drives the impact device connector to move downward, thereby causing the impact plate to impact the plate to be impacted;

[0099] Step 3: Heat treatment of the impacted plate by means of a heating device. After the heat treatment is completed, the rolling is completed.

[0100] The best embodiment, this embodiment is a further description of the second embodiment. In this embodiment, step 1 further includes heating the plate to be impacted by a heating device, and detecting the temperature of the plate to...

The purpose is to solve the problems of easy cracks, relatively coarse crystal grains, uneven work hardening and poor plasticity in the existing rolling. The plate rolling device includes an impact mold, a magnetic pulse impact unit and a heating device; the impact mold includes The upper mold, the lower mold and the guide device; the upper mold and the lower mold are set up and down correspondingly, and the guide device is connected between the upper mold and the lower mold; the magnetic pulse impact unit includes at least one impact drive device and one impact plate; at least one impact drive The device is arranged in the upper mold, and the impact driving device can impact or reset in the direction of the lower mold relative to the upper mold; the bottoms of all the impact driving devices are fixed to the top surface of the impact plate; the heating device is 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 impact-modifying a plate by using magnetic pulses. Background technique [0002] The existing rolling process is to produce sheet by hot rolling and warm rolling of ingots on a rolling mill, and sometimes cold rolling at the end. After the plate is heated to the hot rolling temperature, the latent slip system is activated to improve the plasticity of the alloy, and the rolling stock is always rolled in the hot rolling range for multiple passes. [0003] However, the heating temperature of the sheet during hot rolling is not easy to be uniform, which is inconvenient for industrial production; the cold rolling process can improve the mechanical properties of the sheet and the quality of the rolled piece, but it is easy to crack the sheet. Moreover, although the existing rolling process can refine the microstructure and grains of the sheet, it can impro...
