Abstract (en)
[origin: US4718645A] A ladle stand for treating molten metal includes a vertically liftable and lowerable lance carrying car arranged above a ladle placed in the treatment position. On the car, a reservoir for a treating agent is arranged and adapted to communicate with a cavity of the lance. The lance carrying car is movable to a lance exchange station laterally of the deposited ladle. In order to move the lance carrying car between the deposited ladle and the lance exchange station in a simple manner and with rather low structural expenditures, by ensuring a troublefree lance exchange without manual operations, a stationary vertical rail guide for the lance carrying car is each provided above the ladle placed in the treatment position and above the lance exchange station. A carriage accommodating the lance carrying car is displaceable between the upper ends of the two rail guides. The lance carrying car is equipped with a lance manipulator to hold and release a lance.
