Abstract
Manipulator for guiding of devices for treatment of heats in furnaces, ladles and the like, e.g. lances for injection of oxygen through a door (3) of an electromelting furnace, consisting of a feed table (19), on which one or several devices (24,29) are arranged displaceable mechanically guided in its length direction by means of one or several feed devices, at which the feed table (19) is movable mechanically guided between an advanced position at a work point (14), where the feed table (19) is immediately in front of the furnace door (3) or the like, at which the devices (24,29) can be inserted into the furnace (2) and possibly lowered down into the heat, and a retracted position, where the feed table (19) is removed from the furnace door (3).
Claims9
A manipulator apparatus for supporting and moving at least one elongated treatment device toward and away from an opening in a furnace and for moving each elongated treatment device into and out of the furnace through the opening therein, said manipulator device comprising
- a support stand which is attachable to the furnace so as to be positioned laterally of the opening in the furnace,
- a swinging bracket which is attached to said support stand so as to be horizontally and vertically rotatable with respect thereto, said swinging bracket having a free end which is remote from said support stand,
- a first hydraulic cylinder attached to the free end of said support stand and including a movable piston having a free end which mounts a rotatable support head, and
- an elongated feed table attached to said rotatable support head so as to be horizontally and vertically movable with respect thereto and also displaceable in its longitudinal direction, said elongated feed table being capable of supporting at least one elongated treatment device,
- said swinging bracket and said first hydraulic cylinder being capable of moving said rotatable support head in front of the opening in said furnace and said elongated feed table being movable relative to said rotatable support head to enable each elongated treatment device supported thereon to extend through the opening in the furnace at a desired angle.
An apparatus for treating the contents in the interior of a furnace which has an opening leading to its interior, said apparatus including
- a support stand which is attachable to the furnace so as to be positioned laterally of the opening in the furnace,
- a swinging bracket which is attached to said support stand so as to be horizontally and vertically rotatable with respect thereto, said swinging bracket having a free end which is remote from said support stand,
- a first hydraulic cylinder attached to the free end of said support stand and including a movable piston having a free end which mounts a rotatable support head,
- an elongated feed table attached to said rotatable support head so as to be horizontally and vertically movable with respect thereto and also displaceable in its longitudinal direction, said elongated feed table being capable of supporting at least one elongated treatment device, and
- at least one elongated treatment device mounted on said elongated feed table,
- said swinging bracket and said first hydraulic cylinder being capable of moving said rotatable support head in front of the opening in said furnace and said elongated feed table being movable relative to said rotatable support head to enable each elongated treatment device supported thereon to extend through the opening in the furnace at a desired angle.
