The disclosure provides a micro control device for simulating the electric thermal field change of a plate/strip, comprising a plate shape simulating test platform, a high current regulating power supply, a current regulating device, a thermal imager, a thermocouple, a non-contact type full field strain gauge, a high-power current control device and an electro-plastic control system; for a plate/strip with large width to thickness ratio and high hardness and brittleness alloy, different numbers of electrodes are arranged laterally along the movable supporting beam. A high-power current control device is used to realize the sub-regional control of the electric field, thermal field and stress field of the plate/strip; at the same time, the movable supporting beam and tension sensor are used to test the working conditions of the plate/strips with different lengths and widths, to simulate the instantaneous synchronous entanglement process between different fields.

The device provides a high-precision physical test platform for studying the non-uniform electro-plastic effect of a high width to thickness ratio and high hardness brittle strip during an actual rolling process, and adds a new and high-efficiency adjustment method to the traditional rolling mill system.

Systems and methods of non-contact tensioning of a metal strip during metal processing include passing the metal strip adjacent a magnetic rotor. The magnetic rotor is spaced apart from the metal strip by a first distance. The systems and methods also include tensioning the metal strip through the magnetic rotor by rotating the magnetic rotor. Rotating the magnetic rotor induces a magnetic field into the metal strip such that the metal strip is tensioned in an upstream direction or a downstream direction. In other aspects, rotating the magnetic rotor induces a magnetic field into the metal strip such that a force normal to a surface of the metal strip is applied to the metal strip.

The present disclosure discloses a method for heat treating an iron-carbon alloy. The method comprises acts of heating the iron-carbon alloy to a first pre-determined temperature at a pre-determined heating rate, holding the iron-carbon alloy at the first pre-determined temperature for a pre-set period of time. The method further comprises acts of cooling the iron-carbon alloy to a second pre-determined temperature at a pre-determined cooling rate and inducing magnetic field on the iron-carbon alloy selectively during at least one of heating and cooling of the iron-carbon alloy. The induction of magnetic field on the iron-carbon alloy results in microstructural changes to improve formation of pearlitic structure in the iron-carbon alloy.
