This type of induction melting system is made up of two converters, one of which is running on full power for the melting process, while the other converter only works on ten percent for holding purposes.
After the completion of the melting process on one furnace input power shifts from melting to holding converter by triggering the transfer switches of the system. While analysis of the molten metal, material addition to the compound and casting continues, the switch allows the system to continue melting on the second furnace during this time allowing the user to save precious time.
Advantages of Melt & Hold systems:
Investment cost is much more feasible(compared to dual inverter systems)
vecofoundry constant power technology speeds up the melting by having the power at 100% at all times leading to an approximate 10% time save. In regards to this, with a six ton furnace working three shifts a day, user can collect an additional twenty tons of product compared to other melting systems.
Two independent converters increase the dependability of a system, decreases their downtime during a failure.
Specifications of the hold converter, such as the power or frequency can be adjusted to the user’s needs.
