Beyond basic dimensions the electrode regulating system water cooled panels and refractory design greatly affect daily reliability. HH Metallurgy equips AC DC and ultra high power electric arc furnace with PLC controlled electrode positioners proportional valves and accurate impedance tracking to minimize arc fluctuation. You should check the type of electrode holder copper clad or bi metallic cooling method of roof and side wall panels and expected campaign life of hearth and side wall bricks. Our engineers explain phase arrangement delta or star connection reactive power compensation scheme and recommended electrode brand grade to help you plan spare parts inventory. A responsible electric arc furnace supplier will state allowable overload duration temperature rise limit of busbar and short circuit withstand capacity of the secondary circuit. During factory acceptance test we demonstrate no load run electrode lift speed and cooling water leak detection so you see these parameters verified not just written on paper. Reviewing such details prevents mismatch between furnace capability and your actual melting practice.

Do not overlook auxiliary interface parameters. The electric arc furnace must specify fourth hole flue gas temperature dust concentration and required extraction volume for proper deduster sizing. HH Metallurgy designs hood size damper ratio and duct diameter according to furnace power and confirms compliance with your countrys emission regulation often aiming at ultra low emission levels. You should also confirm voltage grade control cabinet IP rating noise level and provided safety interlocks such as furnace tilt lockout door open prohibition and emergency stop logic. HH Metallurgy includes English operation manuals PLC program backup and on site commissioning in the scope so overseas clients can operate confidently. We have delivered complete electric arc furnace lines with ladle furnace continuous caster and dedusting system since 2008. Choosing HH as your electric arc furnace manufacturer means every critical parameter is discussed documented and tested before shipment.
