  • Mold stator for electromagnetic stirring
    Patent number: 4454909
    Abstract: A means for electromagnetic stirring of steel in a continuous casting operation comprises at least two multi-turn conducting loons. Each turn has a group of winding segments running longitudinally along a mould side, such connected in series to another group of segments running longitudinally along the opposite mould side. Such an arrangement provides a rotating field which produces flux across the mould, transverse to the casting direction.

  • Method of slitting a double or triple stranded bar
    Patent number: 4193283
    Abstract: In the high speed production of elongated metal bars, a method of slitting a double or triple stranded bar interconnected at a continuous node or nodes, in which the bar is rolled to reduce the cross-section of each strand equally, the compressive working force being applied to create lateral tensile forces whereby the strands diverge and separate. In a triple stranded bar the two outer strands are worked in the same manner to separate them from the central strand.

  • Device for slitting billets
    Patent number: 3982455
    Abstract: A device for slitting billets rolled to produce a multiple stranded bar, in which a guide member and support rollers direct the multiple stranded bar, emerging from a stand, against a rotary knife having a circular blade bevelled peripherally to provide shoulders over which individual strands will ride, thus splitting the bar in advance of the knife. Passages behind the knife channel the individual strands.
