Definitions

  • the furnace body With the conventional form of smelting furnaces, the furnace body is fixed in a tilting frame by means of bolts which in the case of large furnace units are large and heavy. It is therefore an arduous and lengthy operation when the furnace body has to be removed and replaced by a new one. Furthermore, before this operation can be undertaken, it is generally necessary to remove part of the furnace platform which is connected to the furnace crucible and tilting frame.
  • An object of the invention is therefore to provide an arrangement whereby it is possible to exchange the furnace body in a very simple manner without having to loosen any screw connections.
  • a further object of the invention is that the connection between the furnace body and the tilting frame should be such that the furnace crucible can be tilted for pouring purposes without the risk of the crucible slipping out of the tilting frame.
  • FIG. 1 shows an elevational view of a smelting furnace.
  • FIG. 2 is an elevational view of the upper part of the furnace unit, partly in section.
  • FIG. 3 shows the furnace body in elevation when withdrawn from the supporting frame.
  • FIG. 4 is a plan view of part of the furnace unit.
  • the smelting furnace unit consists essentially of a tiltable frame 1 which supports the furnace body 2.
  • the frame 1 comprises two lateral beams 5 and two transverse struts 6 which are welded together to form the frame structure.
  • the frame 1 which is tiltable is provided at the front end of each lateral beam 5 with a pivot 7 located in the top of the furnace stand 8.
  • Each lateral beam 5 is connected by way of a pivot bearing 9 to the piston rod of a hydraulically operated tilting cylinder 10 which can swivel about the axis 11.
  • each lateral frame beam 5 is provided with a pair of supporting pins 12, rigidly fixed to the beam for instance by welding, which engage with corresponding pockets 13 rigidly fixed to the outside of the furnace body 2.
  • These pockets 13 are in the form of U-shaped slots so arranged that they are 3,319,298 iatented Mar. 21, 1967 lCC inclined to the vertical axis of the furnace and are open at the lower end.
  • the furnace body When the furnace has to be tilted for the purpose of discharging the melt from the furnace crucible 2 by way of the spout 15, the furnace body is tilted together with the frame 1 about the pivots 7 by means of the tilting cylinder 10 until it reaches the position indicated in FIG. 1 by the chain lines.
  • the shape and arrangement of the bearing pockets 13 prevents the pins 12 from slipping out of the pockets even when the furnace body is in the pouring position.
  • a device for smelting metals comprising a furnace body and a tiltable frame for supporting said furnace body, and cooperating means on said furnace body and said tiltable frame respectively, for holding the furnace body in the frame during the operation of the furnace, said cooperating means consisting of pins which engage with corresponding open slots which are inclined with respect to the vertical axis of the smelting device, whereby the furnace body when in the vertical position can be lifted freely out of the frame but is restrained when the furnace body is tilted.
  • a device as in claim 1 characterized in that at least two pins are rigidly fixed to the tilting frame which cooperate with inclined open slots located on the furnace body with the openings of said slots directed downwards.
