Strip made from a cobalt-iron alloy, laminated core and method for producing a strip made from a cobalt-iron alloy

摘要

A method for producing a strip from a CoFe alloy is provided, in which a slab consisting essentially of 35% by weight Co 55% by weight, 0% by weight V 3% by weight, 0% by weight Ni 2% by weight, 0% by weight Nb 0.50% by weight, 0% by weight Zr + Ta 1.5% by weight, 0% by weight % Cr 3% by weight, 0% by weight Si 3% by weight, 0% by weight Al 1% by weight, 0% by weight Mn 1% by weight %, 0% by weight B 0.25% by weight, 0% by weight C 0.1% by weight, remainder Fe and up to 1% by weight impurities to form a hot rolled strip hot-rolled and quenched from a temperature above 700 ° C to a temperature below 200 ° C. The hot-rolled strip is cold-rolled into a cold-rolled strip, the cold-rolled strip is stationary annealed to produce an intermediate strip, and the intermediate strip is annealed continuously.
