1 Introduction
1.4. Technical Data
1.1. General description of the Degutron
®
eco
With this casting machine, the melting charge is heated up
by induction. Following the liquid material is cast into the
mould.
The special advantage of inductive heating is that the mel-
ting temperature is reached rapidly, because the heat is di-
rectly generated in the metal. During the melting process,
the metal is thoroughly mixed by means of a magnetic
field, ensuring a homogenous mixing.
1.2. Machine components
The machine consists of separate units built into one
casing:
a) Inside the casing, the following components are
installed:
– microprocessor controlled induction generator
– medium frequency transformer
– oscillation circuit capacities
b) The front panel consists of:
– operating panel for control of melting cycles
