摘要： In a grain-oriented electromagnetic steel sheet which is produced by a process including a cold-rolling step(s), the final reduction ratio of the cold-rolling step(s) being high, a technical means for refining the secondary recrystallized grains is particularly important. One technical means is the incorporation of tin into silicon steel material. This, however, involves a problem because tin incorporated into silicon steel material deteriorates the surface coating which imparts tension to a grain-oriented electromagnetic steel sheet.The incorporation of copper into silicon steel material has been avoided since it causes secondary recrystallization to be unstable.The present invention is characterized by the combined incorporation of tin and copper into molten steel so as to simultaneously refine the secondary recrystallized grains and to form a good surface coating. The grain-oriented electromagnetic steel sheet of the present invention contains from 2.5% to less than 4.0% of silicon, from 0.03% to 0.15% of manganese, from 0.03% to 0.5% of tin, and from 0.02% to less than 0.3% of copper.

摘要： The present invention relates to an improvement in the precipitation annealing of a hot-rolled steel sheet or strip which is carried out immediately before cold-rolling in the production of a grain-oriented electromagnetic steel sheet or strip. Conventionally, precipitation annealing is carried out by heating a steel strip to a temperature of from 750.degree. to 1200.degree. C. and then quenching it. The present invention proposes to control the cooling rate during primary cooling, i.e. from a holding temperature (T.sub.1 temperature) of from 1080.degree. to 1200.degree. C. down to an intermediate temperature (T.sub.2 temperature) of from 900.degree. to 980.degree. C., and to control the staying time during primary cooling so that excellent magnetic properties can be obtained regardless of the unavoidable variation in the Al and Si content. The present invention also proposes to control the rate of temperature elevation between 800.degree. C. and the holding temperature as to obtain AlN particles having an optimum size.

摘要： A grain-oriented electromagnetic steel sheet has an ultra low watt loss and heat resistant subdivided magnetic domains. The electromagnetic steel sheet has spaced apart regions of plastic strain and an insulating coating disposed thereon. Intruders are thermally intruded into the spaced apart regions of plastic strain causing the subdivided magnetic domains to be heat resistant and maintaining the subdivided magnetic domains after stress relief annealing. Preferred intruders include Sb and Sb containing materials.

摘要： Method for subdividing the magnetic domains of a grain-oriented electrical steel sheet is improved so that the watt loss can be further lessened and the watt-loss improving effect does not disappear during stress relief annealing. An intrudable means is formed on the finishing-annealed steel sheet on or in the vicinity of strain which promotes the intrusion of an intrudable means. Sb or Sb containing material is a preferred intrudable means and the laser irradiation is a preferred method for imparting the strain and also for attaining the removal of a surface coating.
