are used as holding and storage vessels in continuous and non-continuous foundry operations. Unforeseeable problems can also occur in continuous casting operations, which can then be rectified with the aid of storage furnaces. Storage furnaces are designed as channel furnaces or crucible furnaces with good heat insulation. A crucible storage furnace has the advantage of total emptying over a channel furnace, which must always be operated with a sump. The heat losses are as follows for 40-t furnaces:
a) normal crucible melting furnace approx. 400 kW
b) crucible storage furnace approx. 300 kW
c) channel furnace 40 t usable capacity/12 t sump approx. 250 kW
