3 Phase Electric Arc Furnace

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.

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. The furnace roof is closed when power is supplied to the system. A 3 phase electric arc furnace has the following data. One example of a three phase load is the electric arc furnace used in steelmaking and in refining of ores.

A water cooled copper f1x1 ure provides for continuous tapping of slag. In many european countries electric stoves are usually designed for a three phase feed. 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.

The three phase electrical input serves as the main energy input in the electric arc furnace. In are presented models of electric arc from which the authors used in their simulations the model based on formulas that relate arc radius length the arc voltage and the current. The 3 phase system is transformed into three single phase systems that are much simpler to analyze.
