  • Patent number: 6539273
    Abstract: A continuous caster is controlled by a method anticipating the liquidus temperature in the mold of the caster to prevent premature solidification. The temperature in the tundish is measured and based upon the tundish temperature and the resistance time of the molten metal in the tundish, an equivalent liquidus temperature window is defined and the speed of the continuous caster is controlled to maintain this window of operation of the tundish.

  • Patent number: 6349581
    Abstract: Rolling stock is transported in a transporting device from a front roll stand to a rear roll stand. Between the roll stands, the rolling stock carries out an oscillation transverse to the transporting direction. At least one characteristic property, amplitude or frequency, of the oscillation is determined quantitatively and, from this determination, a tension or compression, existing in the rolling stock between the roll stands is determined. One of the roll stands is readjusted in such a manner, that a desired tension is built up in the rolling stock between the roll stands.

  • Patent number: 6227091
    Abstract: A hook conveyor moves a succession of coils having outer turns through a trimming station in a transport direction with each coil lying at the station in a plane generally parallel to the direction. A trimming apparatus has a pair of supports flanking the conveyor at the station and each movable between outer and inner positions, respective guides on the supports defining respective vertical guide planes generally parallel to the direction, and respective shears movable on the guides long the respective guide planes. Respective actuators displace the shears along the respective planes and, in the inner positions of the respective supports, cut the outer turns from a coil in the station. Respective separating wedges are displaceable on the guides generally radially of the coil in the station to separate the respective outer turns from the coil.

  • Patent number: 6173596
    Abstract: A position detector used with a roll stand having a fixed frame member and a roll-carrying member movable in a direction relative to the frame member, has first and second sleeves telescoping in the direction adjacent the members, a mount securing one of the sleeves to one of the members, and a fixed-length but elastically bendable link rod extending in the direction and having one end fixed to the other of the members and an opposite end fixed to the other of the sleeves. Thus on relative movement of the fixed and movable members the sleeves slide in the direction in each other. A sensor rod having one end fixed in the first sleeve extends in the direction into the second sleeve. A position sensor in the second sleeve juxtaposed with the sensor rod determines a position of the members relative to each other in the direction.
