Safety in electroheat installations - Part 11: Particular requirements for installations using the effect of electromagnetic forces on liquid metals

2Scope / Description

This part of IEC60519 applies to installations predominantly using the effect of
electromagnetic forces on liquid metals:
- installations for electromagnetic (induction) stirring or transport of liquid metals at low frequencies;
- installations that influence the pouring process by an electromagnetic field;
- parts directly affected by the electromagnetic stirring, transport or pouring installation.
Examples of application:
- stirring devices for casting machines, arc furnaces, ladles, etc.;
- transport of liquid metal for emptying or filling furnaces, launders or moulds;
- devices to transport liquid metal with simultaneous proportioning of the transported quantity, for example, for filling diecasting machines;
- influencing the ingot surface or the pouring stream enhancing crystallization by means of an electromagnetic field during continuous casting;
- sealing of mechanical gaps of melt vessels, for example, in vertical galvanizing line. This standard consists of
- requirements common to installations using the effect of electromagnetic forces on liquid metals;
- specific requirements for electromagnetic pouring equipment (Annex A);
- specific requirements for electromagnetic equipment with lining (Annex B).
NOTE When applying IEC 60519-1 in conjunction with this standard, the terms "electroheat installation" or "electroheat device" should be replaced by the term "installation using the effect of electromagnetic forces on liquid metals".
