A submerged arc furnace (SAF) operates by using electric arcs generated between electrodes that are submerged in a bed of raw materials, typically including metal ores, fluxes, and carbonaceous materials. The electric current passes through the materials, generating heat and causing them to melt and react chemically. This process allows for the efficient production of metals, particularly ferroalloys and silicon, as it can operate at high temperatures with a high degree of energy efficiency. The molten metal and slag are collected at the bottom of the furnace, while off-gases are managed for environmental compliance.
What else can I help you with?
What is electrical arc?
Electrical arc is the discharge of charges in the air-gap between two electrodes. When the electrodes are excited the air between the electrodes get ionized and star conducting which causes cotinuous spark between them called arc.
Will gas furnace still work if central cooling air conditioner is taken out?
yes.
Is a solar furnace dangerous?
Provided you are nowhere near the focal point of the furnace then they are perfectly safe.
Use the word furnace in a sentence?
The man ran into the hot furnace to save the boy that was stuck in there.
What is the purpose of the vent on a gas furnace?
The purpose of the vent on the furnace is to ventilate flue gases out side of the house.
What is the diameter of submerged arc furnace?
Submerged Arc Furnace is also called smelting furnace. The furnace is called submerged Arc because Soderberg(Carbon) Electrodes are , buried inside the charge mix. Though Arcing is there but can not be seen. This Furnace is used for producing Ferro Alloys,Pig iron,Silicon metal, Calcium Carbide, Ferro Silicon,Ferro Chrome, Silico Manganese
Who are suppliers of the submerged arc furnace?
Vaibhav Furnaces is the supplier.
What are tapping fumes in submerged arc furnace?
Tapping in the furnace means " Taking out the liquid metal/ferro alloy" . It is a cyclic event.
What is the Name of Electrodes of Submerged Arc Furnace?
The electrodes used in a submerged arc furnace are typically made of high-grade carbon or graphite. They are referred to as "electrodes" or "carbon electrodes," and they are inserted into the furnace to conduct electricity and facilitate the melting of materials, such as metal ores or ferroalloys, by generating heat through electrical resistance. The electrodes are submerged in the charge material, which allows for efficient heat transfer and chemical reactions.
Why electrode is submerged in submerged arc furnace?
Electrodes are Submerged in the Submerged Arc Furnace, into the raw materials. Reason, for allowing the electrodes to reside inside the charge mix, is the high resistance of the ores. Three purposes are served : 1. The heat coming out from arcing is utilized for preheating the ore at the upper strata. 2. Ore/Coke dust from reaction gases is entrapped in the charge mix, this increases the efficiency. 3. In case of power failure, the heat is retained in the molten alloy, meaning very low heat loss to the atmosphere.
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.
Type of weld for Lsaw pipes are double submerged arc welding?
No. Double Submerged Arc Welded is DSAW; LSAW stands for Longitudinal Submerged Arc Welded. As an aside, HSAW stands for Helically Submerged Arc Welded. All of these refer to various types of pipe manufacturing processes.
Will a furnace leak gas if a basement floods?
Probably not, but if the furnace or a part of it was submerged you should have it checked out.
Why is submerged arc welding referred to as submerged?
Submerged arc welding is called "submerged" because the high voltage electrical current (called the "arc") that heats the metal and wire to weld together is submerged underneath layers of granular earth materials called "flux". About 50% to 90% of this flux can be re-used and fed back into the system with the proper equipment.

What is the mass of steel when in an arc furnace?
400kg
How do you calculate arc length between electrode and charge in arc furnace?
Arc Length depends on the secondary voltage of furnace transformer. Thumb rule is for 500V the Arc length would be 500mm(20"). The purpose of arc length is to give maximum power to the melt, without arc flare. -
