Abstract
Apparatus for repairing electric furnaces, ladles or the like while they are hot and which includes a centrifugal slinging machine that can be lowered into the hot furnace. The machine includes a centrifuging wheel which can deliver lining repair material radially outwardly and against the interior wall of the furnace. The centrifugal delivery portion of the machine can be selectively divided into sectors so that repair material can be selectively dispersed only against that portion of the interior furnace wall that needs repair or alternatively, the machine can deliver material to the entire circumference of the interior of the furnace. The machine has adjustable sliders which are provided around the circumference of the machine to selectively distribute the material around the interior of the furnace and the sliders are infinitely variable in their adjustment, and radial director vanes act in cooperation with the sliders. The machine also has a mixing worm vertically above the centrifuging wheel and located in the bottom of the material supply hopper. An upwardly tapering and stepless supporting cone is located in the hopper and is also vertically adjustable so as to form a variable annular clearance with the upwardly diverging hopper. An automatic clamping device is provided for selectively securing the machine on a supporting arm, whereby the machine can be quickly and easily adjusted in a variety of positions.
