Although China’s stainless steel industry has developed rapidly, it is still energy-intensive, highly polluting and inefficient compared with industrial developed countries. Taking 304 stainless steel as an example, because it is prone to serious work hardening during production and processing, and the forming property is poor, it is necessary to perform multiple annealing treatments during rolling, drawing, etc. to reduce or eliminate work hardening. For the subsequent process. Multiple annealing not only consumes time and energy, but also has serious environmental pollution and other issues. Therefore, it is of great significance to find a clean, environmentally friendly, energy-efficient, and efficient production process.

Experiments show that when cold rolling, the deformation resistance of the material is as high as 16.5 kN. After the pulse current is introduced, the deformation resistance of the material is obviously reduced, and the decreasing range is larger and larger with the increase of the frequency of the electric pulse. When a pulse current of 500 Hz is applied, the deformation resistance of the material is reduced to about 12.2 kN and the reduction is as high as 26%.

The test results on the specimens show that the hardness of the specimen increases with the increase of the deformation, whether it is cold-rolling or electro-rolling, but the degree of cold-rolling is much higher than that of electro-rolling. In electro-rolling, after reaching a certain amount of deformation, the hardness of the sample tends to a stable value. After reaching an extremum, the tensile strength began to decrease. Accordingly, the elongation of the specimen first showed a decreasing trend, reaching a minimum point. After slowly rising. This shows that there is an optimal frequency in the electro-rolling process. At this frequency, the best match between strength and plasticity can be achieved. At this time, compared with the original sample in the solid solution state, the electro-rolling test with a deformation of 50% is performed. It has both high tensile strength and good plasticity.

Their work shows that high-energy electric pulses can effectively reduce the work hardening of materials and improve their plastic deformation properties, so that they can increase the number of rolling passes without increasing intermediate annealing and increase the total deformation, making it easier to obtain even thinner sheets. Sheet metal strips. This is a clean, environmentally friendly, energy-efficient and efficient production process route.
