  • Launder for casting molten copper
    Patent number: 7700036
    Abstract: The invention relates to a launder construction for the conveyance of molten metal. The metal flows in the lower part of the launder construction in a channel defined by a refractory mass, the launder being heat-insulated so that, in operating conditions, the metal forms a solid zone in the porous refractory mass. The essential features of the launder construction include a cover part that is provided with electrical resistors, ensuring that the metal remains melted and the launder sufficiently hot throughout the process, and a gas burner that prevents the metal from cooling under the effect of the gas flowing in the launder channel.
    Type: Grant

  • Arrangement for conveying a plate-like product from one position to another
    Patent number: 7258224
    Abstract: An arrangement for conveying an anode plate from one location to another, whereby said arrangement comprises gripping elements attached to a conveyor for gripping a plate-like piece. Elements are attached to the gripping element connection for the correction, at least partial, of any possible positional error of the anode to be transferred.
