Carbon Steel Versus Stainless Steel in the Design of Electrode Arms for UHP Electric Arc Furnaces

Peter F Ryff

V. A. Bulat²

Abstract: The operating temperatures due to eddy current induced heating effects in water-cooled electrode arms of three-phase ultrahigh powered (UHP) electric arc furnaces during operation are calculated. The selection of commonly used materials (carbon steel -SAE 1010 and stainless steel -304) is examined with regard to optimum cooling water flow and safe allowable temperature increases. Calculated results are substantiated by temperature measurements conducted on the center-phase electrode arm and its water cooling s… Show more

A high current, forced water cooled bus system is analyzed, which forms part of the electrode arms in a three-phase electric arc furnace betwecn the flexible cables and the electrode holders. Due to the electrical imbalance of the three-phase secondary high-current network, unbalanced power input has caused design and operating problems. The analysis presented deals with the bus-enclosure system, with the objective to analyze the different enclosure arrangments, and to control the electrical parameters. The calculated results are substantiated by measurements, indicating that the enclosure dimensions and its material do influence the electrical parameters considerably. Some optimization can be done thereby placing less demand on the cooling system.
