The furnaces are hearth-type. The transfer of heat to the metal is by heat radiation from glowing ceiling and as well as from SiC heating tubes themselves.


The furnaces have been designed so that they have two chambers:

  • an antechamber for charging
  • a chamber with heating elements


The antechamber is separated from the chamber accommodating heating elements by partition wall. The partition wall protects heating elements against possible spurts of liquid metal and assures a still alloy in the chamber accommodating heating elements. On the front side of the latter there is an opening serving to treat the alloy and to visually check the state of the heating elements. The furnaces can be stabil or tiltable.


Advantages of the stationary furnaces with SiC heating elements:

  • high heat efficiency of the furnace
  • minimum consumption of electric power for melting and temperature maintenance
  • low percentage of burnout
  • possibility to treat the furnace with salts against corundum formation on the furnace walls
  • minimal interruptions due to the replacement of heating elements
  • possibility to start the furnace with frozen alloy
  • lower maintenance costs in comparison to conventional electric resistant heartg-type or crucible melting furnaces
