Crucible storage furnaces are in principle designed in the same way as crucible melting furnaces. Depending on their particular application however, they are equipped with significantly better heat insulation and sometimes also an induction coil, split into sections. In the case of a 50% division, both coils will for example have an output of 3,000 kW. When both coils are switched in series, the total output is only 1,500 kW. Crucible storage furnaces have the advantage that in the event of problems, stoppages or other interruptions, they can be completely emptied. Due to the low specific output, it is advisable to sinter crucible storage furnaces with molten iron.
