The processing of many material billets after they are cast is often an important feature.
The high-energy electric pulse technology is taken as a novel technology capable of effectively improving the organization and the performance of materials at high speed, and the main work at present is focused on the following three aspects:
1) The high-energy electric pulse treatment is carried out on the solid metal, so that the microstructure evolution and performance of the material can be controlled, including grain refinement, segregation reduction and microstructure morphology change. In the metal rolling process, by applying a directional pulse current to both ends of the processed material, the deformation resistance of the material can be quickly and effectively reduced and the plasticity of the material can be improved.
2) The high-energy electric pulse treatment is carried out on the solidification process of the liquid metal, and when the metal material is in a solid-liquid two-phase region, the high-energy electric pulse treatment can obviously improve the cast structure of the material, can accelerate the formation of crystal nuclei, and simultaneously inhibit the growth of crystal grains to obtain uniform and refined crystal grains.
In the prior art, there are many processes for roll forming metallic materials using high-energy electric pulse technology, but many exist only in laboratory test results. For example, the prior art discloses an electro-plastic rolling method and system for wrought magnesium alloy sheets, strips and wires, wherein a phenomenon of increasing the plasticity of a local processing area is caused by introducing instantaneous high-energy pulse current during rolling. The process applies laboratory experimental results (such as rolling speed and deformation) to the magnesium alloy rolling process, wherein the rolling speed needs to be manually adjusted in the process, and simultaneously, the motor rotating speed, rolling extrusion force, traction force, pulse current frequency, current density, pulse width and other parameters need to be readjusted in each pass of introduction of instant high-energy pulse current. The technology is to utilize the coupling effect of the heat effect and the non-heat effect of the high-energy pulse current to induce the recrystallization rapidly when the AZ91 magnesium alloy is rolled. The process needs to replace a rolling mill after one pass of rolling, and resets related parameters. And the prior art discloses a ultrahigh frequency induction heating rolling technology of deformed magnesium alloy wires, which is to heat the magnesium alloy wires to 250-450 ℃ and then carry out hot rolling processing.
The initial parameters of the process method are all test results obtained according to a laboratory, and are all tested by setting a certain step length by a variable control method, so that the process method has a certain limitation and can not judge whether the process is the optimal process. Meanwhile, the traditional processing technology and equipment are used for processing materials, so that the phenomena of high labor cost, uneven structure, poor quality of rolled products and the like can occur.
