    摘要: The present invention refers to a process for the production of electrical steel strips, in which a strip directly cast from molten steel and containing alloy elements apt to generate a precipitation of sulphides and/or nitrides apt to inhibit the grain growth, is hot rolled in-line with the casting operation, at a temperature comprised between (1250) and (1000) DEG C, and in which said strip is coiled after hot rolling at a temperature of less than (780) DEG C if sulphides are utilised, or at a temperature of less than (600) DEG if nitrides, or nitrides plus sulphides, are utilised. A final product is thus obtained having excellent and constant magnetic properties.

    摘要: A production method includes producing a rare-earth magnet precursor (S') by performing first hot working in which, in two side surfaces of a sintered body, which are parallel to a pressing direction and are opposite to each other, one side surface is brought to a constrained state to suppress deformation, and the other side surface is brought to an unconstrained state to permit deformation; and producing a rare-earth magnet by performing second hot working in which, in two side surfaces (S' l, S'2) of the rare-earth magnet precursor (S'), which are parallel to the pressing direction, a side surface (S'2), which is in the unconstrained state in the first hot working, is brought to the constrained state to suppress deformation, and a side surface (S' l), which is in the constrained state in the first hot working, is brought to the unconstrained state to permit deformation.
