Abstract
A feeder container for arc furnaces is disclosed having fold-down bottom segments which are prevented from swinging outward by a ring disposed underneath the container proper to prevent the segments from hitting the furnace wall. The segments are constructed as double-arms levers, with a shorter radially outwardly oriented lever arm in each instance, held down by a bottom ring of an outer jacket, the jacket being provided with windows and the up and down movement of the outer jacket in conjunction with the lever action is used to control the discharge or retention of material kept in an annular space between the container proper and the outer jacket.
Claims3
A container for feeding an arc furnace having a container element proper and foldable or hinged, bottom segments amenable to assume a closing position but upon release folding down for opening the bottom, the improvement comprising
- a container, each of said segments being constructed as a double-arm lever, a second arm in each instance, respectively, extending radially outwardly from a point of hinging;
- annular means extending underneath said container element and limiting radial outer displacement of the segments when folded down,
- and a separate annular ring which acts upon said radially outwardly extending lever arms, tending to fold the segments up toward closing the bottom of the container.
