1 Scope

This part of GB/T 10066 specifies the test procedures, conditions and methods for electric arc furnace (EAF), based on which the capacity is determined. Main parameters and main operating characteristics of AC electric arc furnace (EAFac) or DC electric arc furnace (EAFdc) above 500kg/furnace. The electric arc furnace technology is also suitable for this type of furnace, ie the liquid metal in the furnace is kept at a high temperature or superheated to the pouring temperature [eg a steel ladle using AC) Furnace (LF)]. Test methods for certain special equipment, such as DC arc furnace controlled rectifiers, are specified in IEC 60146-1-1. The test method for the submerged arc furnace (SAF) is specified in IEC 60683.
