What is a submerged arc furnace?

What is a submerged arc furnace? An industrial electric furnace that consumes a lot of electricity and is used to reduce and smelt ore, carbonaceous reducing agent and solvent, and other raw materials is called submerged arc furnace.

The SAF is an electro-metallurgical equipment that uses the arc heat at the end of the electrode and the resistance heat of the charge or slag to convert electrical energy into heat energy so that use elements such as metals are reduced from ores or oxides. Because it is mainly used for the reduction and smelting of metal oxide ore, it’s called SAF or submerged arc reduction electric furnaces. In addition, since most of the arcs of submerged arc furnaces are deeply buried in the charge, they are also called buried arc furnaces.

Use

What is a submerged arc furnace and how to use it?

When the submerged arc furnaces are used to produce ferroalloy, it is called ferroalloy furnaces; when it is used to produce calcium carbide, it is called calcium carbide furnaces; when it is used to produce yellow phosphorus, it is called yellow phosphorus furnaces; when it is used to produce matte, it is called matte furnaces; When refining, it is called submerged arc refining furnaces; when it is used to melt pre-reduced charge and separate metal and slag, it is called SAF (submerged arc furnaces).

In the production of ferroalloys, most of them use coke as a reducing agent and use different raw materials according to the different product varieties. product.

When calcium carbide is produced in SAF, coke is still used as a reducing agent, calcium oxide (lime) is used as raw material, titanium slag is obtained through furnace smelting, and vanadium-containing molten iron and other products are obtained.

Therefore, the submerged arc furnace is a smelting equipment covering ferroalloys, chemicals, ferrous metals, non-ferrous metals, and other industries.

Structure

What is a submerged arc furnace and what’s the equipment structure?

The SAF is mainly composed of a furnace shell, furnace cover, furnace lining, short net, water cooling system, smoke exhaust system, dust removal system, electrode shell, electrode pressing and lifting system, loading and unloading system, controller, burn-through device, hydraulic system,

Submerged arc furnace transformers and various electrical equipment and other components.

Each independent structure has certain characteristics, and we will provide more detailed solutions in the future.
