electric arc furnace the graphite network

power supply

I want to make a mini arc furnace just for fun. I have two 4mm diameter graphite electrodes from an AA battery. I could calculate the loss of heat by radiation, but I dont know the resistance of the arc and I need it to calculate the windings of the transformer that will supply it

Graphite Electrodes is used for the electric arc furnace

Graphite electrodes are used for the recycling of steel in the electric arc furnace industry, so called "mini-mills". They are also used in the refining of steel as well as in the non ferrous industries, where smelting processes are in use. We do not simply provide graphite electrodes and connecting pins as standalone products to our customers.

Electric Arcs

2.6 Electric Arc Furnace Production As output from integrated steel producers declined and electric arc technology improved, smaller-scale electric arc furnaces quickly became an economically attractive alternative to integrated mills—compared, for example, to blast furnaces, which cost around $1 billion and usually operate at scales between 1.5 and 3 million tons per year, as noted by

The intelligent arc furnace controller: a neural network

The amount of power delivered to the scrap metal in an electric arc furnace is controlled by positioning three large electrodes. The authors present quantitative performance results of the intelligent arc furnace regulator and analyze qualitatively how a neural network improved furnace operation. A neural network control system can learn to predict the relationships between the electrode

Electric Arc Furnace – The Graphite Network

Arc furnaces differ from induction furnaces in that the charge material is directly exposed to an electric arc and the current in the furnace terminals passes through the charged material. For steelmaking, direct current (DC) arc furnaces are used, with a single electrode in the roof and the current return through a conductive bottom lining or conductive pins in the base.

electric arc furnace electrodes

Electric arc furnaces utilize graphite electrodes, which are also employed in ladle furnaces via the blast furnace/basic oxygen converter route. Rather than halting production, some mills may work weekends or night shifts, when electricity is cheap and costs
