Successful upgrading of old induction melting furnaces

a contribution to saving energy and increasing melting rates

<font face="Arial" size="2">Considerable energy savings and increases in melting rates can be achieved by upgrading old coreless induction furnaces, and especially by converting them to advanced converter technology. At the same time, downtimes and maintenance and repair of the systems are reduced. As the investment costs only represent a quarter or a third of the costs of new equipment and the implementation often takes no longer than a week, there are other advantages as well.</font><font face="Arial" size="2">&nbsp;</font>

<font face="Arial" size="2">This is backed up by numerous projects successfully realized by OTTO JUNKER in recent years.</font><font face="Arial" size="2">&nbsp;</font>

<font face="Arial" size="2">Tables 1 and 2 show the economic and technical effects on the basis of two examples.</font>

<font face="Arial" size="2">The upgrading projects already implemented have shown that:</font><font face="Arial" size="2">&nbsp;</font>

<font face="Arial" size="2">Converting mains frequency systems to medium-frequency systems brings about energy savings of 8&nbsp;% (for cast iron), and another 10&nbsp;% can be saved if a higher power density is realised.<br></font><font face="Arial" size="2">Replacing old converter systems (quintuplers etc.) by advanced medium-frequency switchgear cuts power consumption by 12 to 20&nbsp;%.<br></font><font face="Arial" size="2">Converting a monomelt into a tandem system (using a second furnace) yields throughput increases of 30&nbsp;%.<br></font><font face="Arial" size="2">Converting to a modern PLC-based control system with the JOKS melting processor reduces downtimes and cuts energy consumption.</font><font face="Arial" size="2">&nbsp;</font>

<font face="Arial" size="2">Using the <strong>O</strong>ptical <strong>C</strong>oil <strong>P</strong>rotection System <strong>(OCP)</strong> improves the safety and reliability of the equipment and consequently reduces downtimes.</font><font face="Arial" size="2">&nbsp;</font>
