DC ARC FURNACES – PAST, PRESENT, AND FUTURE Rodney T. Jones Mintek; 200 Malibongwe Drive, Private Bag X3015, Randburg, 2125, South Africa Keywords: Pyrometallurgy, DC arc furnace, electric arc, smelting Abstract DC arc furnaces were first used industrially for the reductive smelting of chromite fines to produce ferrochromium thirty years ago.
Submerged arc furnace is also called electric arc furnace or electric resistance furnace. It is mainly used to restore smelt ore as well as the material of carbonaceous reducing agent and rholite. Submerged arc furnace mainly produces silicon iron, ferromanganese iron, chromium iron, ferrotungsten, silicon-manganese alloy and other ferroalloys.

The Submerged-arc furnace for phosphorus production is a particular sub-type of electric arc furnace used to produce phosphorus and other products. Submerged arc furnaces are mainly used for the production of ferroalloys. The nomenclature submerged means that the furnace's electrodes are buried deep in the furnace burden.
The furnace may be equipped with automatic rocking equipment. The power factor varies from 0.7 to 0.8. The electrode material and electrical equipment of indirect-arc furnace are similar to that used for direct arc furnace. Submerged Electric Arc Furnace Working Principle
Arc Furnace. Submerged Arc Gold Smelter originally designed for the precious metals smelting industry, but in recent years also adapted for use in other industries world-wide. The equipment is manufactured in South Africa by Keegor SA (Pty) Ltd and is available for world-wide distribution.
Example 3: DC arc furnace for ilmenite smelting •Same DC arc furnace equipment can be used for very different reasons •Titania slag is highly conductive, therefore an open arc is required •Slag is a valuable product; contamination must be avoided •Degree of reduction must be carefully controlled, therefore no electrode immersion

Nov 29, 2014· Induction furnaces are among the best furnaces used for the smelting of metals and the melting of scrap materials. These furnaces are an advanced version of the electrical powered furnaces and use induction heating to produce heat, which is .
Low cost ferroalloy extraction in DC-arc furnace at Middleburg Ferrochrome by D. Sager, D. Grant†, R. Stadle*, and T. Schreiter‡ Synopsis Middleburg Ferrochrome (MFC), a company in Samancor Chrome, commissioned a new ferrochrome smelter in March 2009. This is a 60 MW DC-arc furnace with a DC power supply for the smelting of
A typical pyrometallurgical copper smelting process, as illustrated in Figure 12.3-1, includes 4 steps: roasting, smelting, concentrating, and fire refining. Ore concentration is roasted to reduce impurities, including sulfur, antimony, arsenic, and lead. The roasted product, calcine, serves as a dried and heated charge for the smelting furnace.
Jul 15, 2014· Electric arc furnaces have been used for many years both for the melting of scrap iron (open arc furnaces) and for reduction processes (submerged arc furnaces). In case of the submerged arc furnace (SAF), ore and reducing agent are fed to the furnace continuously from the top so that the electrodes are buried in the mix and the arc is submerged.
DC Electric ARC furnace for Casting iron/Metal refining/Fine cabon steel melting. When ferro ore was reduced to sponge iron by blast furnace, it must be melted by Electric Arc Furnace (EAF) to remove the impurities, then adjust the component to your required steel.
By 1913, the first submerged-arc furnace with six electrodes was operating successfully. In 1950, the first furnaces exceeded the 40,000 kVA power rating benchmark. During the last decade more than 50 different prod-ucts have been processed with SAF and electric smelting technology for .
