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.

According to present invention, the classic composition of high-characteristics silicon steels is improved, utilizing contents of carbon and aluminum shifted towards the lower limits thereof up to now accepted and maintaining anyway low the total inhibitors content, thus allowing to lower the slabs heating temperature, to attenuate the effect of lumping the inhibitors in coarse precipitates, to obtain a good glass-film and to utilize the thin-slab continuous casting technique.

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.
