3 phase electric arc furnace.

Latent heat of steel 37 25 kj kg specific heat of steel 0 444 kj kg c melting point of steel 1370 c initial temperature. Current drawn 9000 a transformer resistance referred to the secondary 0 003 s2 transformer reactance referred to the secondary 0 0052 overall efficiency 65 the charge steel has the following data. The 3 phase system is transformed into three single phase systems that are much simpler to analyze. Individual heating units are often connected between phase and neutral to allow for connection to a single phase circuit if three phase is not available.

This model was presented in. Each phase of the three phase electrical input supplies power to one of the three electrodes that is mounted above the furnace bath through the roof. In many european countries electric stoves are usually designed for a three phase feed. The electrical energy input needs to be controlled with the aim of achieving the lowest possible production cost.

A 3 phase electric arc furnace has the following data. The electric arc furnace is a nonlinear and unbalanced high power three phase charge. The furnace roof is closed when power is supplied to the system.
