Abstract

PURPOSE: To produce a slab for electrical sheets having large contents of C and Si in the central layer and having superior characteristics by adding a wire contg. carbon and silicon into the unsolidified molten steel part in an ingot in casting the blank material for slab for electrical sheets continuously.
CONSTITUTION: The concns. of C and Si in the central layer of a blank material slab are uniformly increased in order to improve the magnetic characteristics of electrical sheets. To this end, the wire which coats the composite additives contg. carbon powder and metallic silicon with metal for coating, is controlled of the pure contents of Si and C to prescribed values and is controled of the pure content weight of Si per unit length × g/m like the equation[I]is added to the unsolidified part in a solidified shell and the melting position of the wire is set at the value wherein the distance L along the strand from the meniscus is given by the equation[II], at the continuous casting of the slag. Electromagnetic stirring is used in combination in the position corresponding to the spray zone corresponding to the above-mentined position of L, whereby the concn. distributions of the C and Si in the central layer of the slag are made uniform.
