Process for the production of grain oriented electrical steel

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 appropriate to generate a precipitation of sulphides and/or nitrides appropriate to inhibit the grain growth, is hot rolled in-line with the casting operation, at a temperature comprised between 1250 and 1000 °C, and in which said strip is coiled after hot rolling at a temperature of less than 780 °C if sulphides are utilised, or at a temperature of less than 600 °C if nitrides, or nitrides plus sulphides are utilised. A final product is thus obtained having excellent and constant magnetic properties.
