摘要： Non-oriented electrical steel sheets having excellent magnetic properties are produced by carrying out a coiling at a low temperature for monitoring the amount of scale generation; de-scaling after hot rolling; and annealing the de-scaled hot rolled sheet in a non-oxidizing atmosphere to thereby minimize the oxidation and nitriding during annealing the hot rolled sheet. By determining a higher heating temperature for hot rolling, a magnetic property (magnetic flux density) is improved, and the hot rolled sheet is subjected to an open coil-annealing and annealing conditions therefor are specified in order to perfectly precipitate re-solute AlN particles by this heating and fully coarsen AlN particles.

摘要： A method of producing non-oriented electrical steel sheets having excellent magnetic properties which comprehends heating a steel at the low temperature for hot rolling, thereby to minimize re-solution of AlN particles when a slab is cooled, so that coarsening of AlN particles is facilitated during annealing the hot rolled sheet; and coiling at low temperatures for controlling the amount of scale generation. De-scaling is perfectly accomplished after the hot rolling, and the hot rolled sheet is annealed in a non-annealing atmosphere, thereby to control the oxidation and the nitriding to a minimum during annealing the hot rolled sheet, and the annealing conditions of the hot rolled sheet are specified for proper coarsening of the cohesion, taking into consideration the magnetic properties and the economics.
