| 摘要 |
The invention relates to a method for the production of cold-rolled magnetic sheet or strip, with non-oriented granularity and a final thickness of </= 0.75 mm, comprising the following working steps: smelting a steel with (in wt. %) C: </= 0.01 %, Mn: </= 1.5 %, Si: 0.1 - 4.5 %, Al: 0.001 - 2.0 %, P: </= 0.1 %, Sn: </= 0.15 %, Sb: </= 0.15 %, the remainder iron and unavoidable impurities, casting the steel to give thin slabs, a heat treatment of the cast thin slab or strip following on continuously after the casting, hot-rolling of the thin slab or strip following continuously after the heat treatment to give a hot strip with a final thickness of </= 1.8 mm, winding the hot strip, cold-rolling the hot strip to give a cold strip with a final thickness of </= 0.75 mm and a final heat treatment of the cold strip. Said invention combines the effects of the application of a continuous casting and rolling unit (in-line casting and rolling) with the effects of the reduction in complexity on cold-rolling by application of continuously cast hot-rolled strip made from FeSi steels with a thickness of </= 1.8 mm, preferably </= 1.2 mm. |
