The expected energy efficiency gains
are due to a new furnace that, by means of a power transmission system based on induction, will allow a highly flexible production. This increase on the production flexibility attends to the current variability of the foundry products demand.
The current crisis has introduced a high variability in the demand, which can be measured in terms of quantity and diversity of the claimed products. The manufacturers are now forced:
- To start and stop many times their production chains
- Change the moulds and, the most important in energy penalty terms,
- To reheat many times big quantities of raw materials.
Consequently, the cost efficiency of the process has suffered a high decrease.
NIWE tackles these actual and current problems by providing a new furnace that will take the power by an inductive coupling. This will provide a very quick power transmission from the grid to the furnace. This power will be supplied to the heating system, which, depending on the foundry material could consist on resistances or induction heating.
The rapidity of the power transmission system, as well as the wireless operation, will allow the use of smaller and more flexible furnaces. This way, the reserve of melted material for feeding the moulds will be smaller, and therefore the required energy to maintain it melted.
