Latest Patents

Chel-Min Park holds a patent for "Non-oriented electrical steel sheets with excellent magnetic properties and method for manufacturing the same." This invention relates to the technology for manufacturing electrical steel sheets that exhibit excellent magnetic properties through the control of hot-rolled texture using the phase transformation of steel. The non-oriented electrical steel sheet developed by Park has reduced iron loss and increased magnetic flux density. This is achieved by controlling alloy component elements and optimizing hot-rolling conditions, even without the need for hot-rolled sheet annealing. The composition of the steel sheet includes 0.005 wt % or less of carbon, 1.0-3.0 wt % of silicon, 0.1-2.0 wt % of manganese, 0.1 wt % or less of phosphorus, 0.1-1.5 wt % of aluminum, and the remainder being iron and other inevitable impurities. The relationship between manganese and aluminum in the steel sheet satisfies a specific equation, ensuring optimal performance.
