There are several ways of charging the Electric Arc Furnace(EAF).
1. 100% Scrap Charging by opening the furnace roof and introducing scrap bucket into the furnace shell. In this process 2-3 charges are taken for reaching the designed capability of furnace. This results heat loss when roof is opened.
2. In latest process DRI/Sponge Iron is fed from roof hopper, continuously, into the molten metal pool.
3. In another process, hot metal(from blast furnace) is introduced from slag door or roof top. This is the most effective method for reducing Tap To Tap Time(TTTT).

What is direct arc electric furnace?
An Electric Arc Furnace (EAF) is a furnace that heats charged material by means of an electric arc.Arc furnaces range in size from small units of approximately one ton capacity (used in foundries for producing cast ironproducts) up to about 400 ton units used for secondary steelmaking. Arc furnaces used in research laboratories and bydentists may have a capacity of only a few dozen grams. Industrial electric arc furnace temperatures can be up to 1,800 °C, (3272 °F) while laboratory units can exceed 3,000 °C. (5432 °F) 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.
What is EAF?
EAF stands for electric arc furnace.

EAF stands for electric arc furnace.
How do you calculate arc length in electric arc furnace?
To calculate the arc length in an electric arc furnace, you can use the formula: ( L = \theta \times r ), where ( L ) is the arc length, ( \theta ) is the angle in radians, and ( r ) is the radius of the arc. First, determine the angle that the arc subtends at the center of the furnace, then measure the effective radius from the arc's origin to the point where the arc terminates. Multiply these values to find the arc length.
How to use copper pad in electric arc furnace machine?
Sensitive equipment like a furnace machine requires the services of a qualified electrician. Call one to have the copper pad in the electric arc furnace machine fixed.
What is gantry mechanism in electric arc furnace?
A gantry mechanism in an electric arc furnace is a movable structure that supports and moves the electrode arms over the furnace. It is responsible for controlling the positioning of the electrodes during the melting process, allowing for precise control over the arc length and power input to the furnace. This mechanism enables efficient melting of metal scrap and ensures uniform heating of the materials in the furnace.
