Industrial electroheating equipment - Test methods for direct arc furnaces

IEC 60676:2024 This document specifies the basic test procedures, conditions and methods for establishing the main performance parameters and the main operational characteristics of furnaces for direct arc heating, forming arcs between the electrode and metal, such as electric arc furnaces using alternating current (EAF AC) or direct current (EAF DC), and ladle furnaces (LF), with rated power level above 500 kVA .

This fourth edition cancels and replaces the third edition published in 2011. This edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous edition:

a) The structure has been redrafted according to IEC 60398:2015.

b) The scope has been redrafted.

c) The terms/definitions, normative references and bibliography have been updated and completed.

d) The test methods and content from IEC 60398:2015 have been confirmed, replaced, or complemented with regards to direct arc furnaces (EAF, LF).

e) The annexes from IEC 60398:2015 have been confirmed, replaced, or complemented with regards to direct arc furnaces (EAF, LF).
