Coreless Holding Furnaces

Like Channel Holding Furnaces, Coreless Holding Furnaces maintain a continuous supply of metal ready to pour twenty-four hours a day, seven days a week.

Inductotherm coreless induction holding furnaces offer many advantages. They combine high productivity with maximum alloy flexibility. Compared to a channel holding furnace, it requires significantly lower capital and installation costs. Our coreless holding furnaces can be emptied to handle alloy changes on short notice and do not require energy-wasting off-shift holding.

When to select a coreless induction holding furnace?

Select a Coreless Holding Furnace when holding requirements cover one or two shifts per day, are less than seven days per week, or when the need to change alloys is required.

Advanced options for increasing efficiency and productivity

Inductotherm coreless holding furnaces with an optional Mini-Heel^® Coil feature uses our patented extension of the inductor coils below the bottom level of the molten metal. This greatly increases electrical efficiency at low metal levels and permits continuous duplexing with as little as a 10 percent heel. This allows a full 90 percent metal volume usage when duplexing, increasing both throughput and productivity.
