Application of Electrodes in Ferro Alloy Furnaces

Ferro-alloy furnaces are electrothermal in nature where heat is produced by supplying electric current through the carbonaceous electrodes to the working space of the furnace. The properties necessary for the satisfactory performance of an, electrothermal

Electrodes

These electrodes are indispensable when it comes to producing silicon metal and ferroalloys, as well as for other silicon metal and alloy products. Not only do we want to offer the best possible solution as suppliers but also, as one of the largest metallurgical producers, we are also a major consumer of electrodes, which is a living proof of its quality.

APPLICATION OF ELECTRODES IN FERRO ALLOY FURNACES

Ferro-alloy furnaces which are to a large extent continuously operating units need high current (upto 50000 amperes in three- phase). For the supply of high current, electrodes of a large' diameter, (20 to 55) are required. But the difficulties of producing quality

What are the Classifications of Electrodes?

The electrodes of submerged arc furnaces are subject to tension, compression, bending, and stress during use. The impurity content should be low. The electrode material contains as little as possible harmful impurities that contaminate the alloy.

Electrode: Meaning, Specification and Uses

Electrodes with a dip coating are dried either in the air or in well-ventilated rooms at room temperature (70 F/21 C) for 12-20 hours until the coating finally solidifies. Coated electrodes are roasted in pot furnaces and ventilated in drying ovens or electric-heated :

DC ARC FURNACES – PAST, PRESENT, AND FUTURE

DC furnaces also experience lower electrode consumption. In large DC furnaces, a higher current can be carried per electrode (or smaller electrodes can be used for the same current), because of the AC 'skin effect' where current is concentrated in the outer

A Study of Ferroalloy Furnace Product Flexibility

Because the majority of the world's sealed ferro- alloy furnaces are located in Japan, a subcontracted study through Mitsubishi Research Institute, Inc. was made of the Japanese ferroalloy industry. The full text of the M*I study of the Japanese ferroalloy sealed furnace operations is presented in the Appendix.

Aston Alloys And Metals

Our graphite electrodes are used in electric arc furnaces (EAF) in the ferrous and non-ferrous melting and smelting industries. The ores and materials our electrodes process include iron, steel, copper, gold, platinum, ferrosilicon [Ferro-silicon, Silicon], mill scale as well as ferroalloys [Ferro-alloy, Ferro alloy].

An electrode Controller for Submerged Arc Furnaces

1980/1/1Such furnaces are used for the production of a variety of ferro-alloys and substances such as calcium carbide by the electrical heating of a mix ture of carbon and metal-oxide ore. The reduction reaction that results causes the formation of a molten pool of the product in the hearth of the furnace, and carbon monoxide gas is released.

Application of Graphite Electrode in Steelmaking Electric

Graphite electrodes are mainly used as conductive materials in electric smelting furnaces. Compared with other conductive materials, the biggest advantage of graphite electrode material is that it has good electrical and thermal conductivity and better toughness, can accept the impact of larger current and does not soften or melt at high temperatures.

SOME ASPECTS OF THE PRODUCTION OF FERROCHROME ALLOYS IN PILOT DC ARC FURNACES

Ferrochrome alloy is predominantly produced in AC submerged-arc furnaces where the electrodes are buried in the burden of lumpy materials comprised of chromite ores or pellets, reductants and fluxes. Mintek has developed and patented the smelting of

Graphite electrodes and electric arc furnaces

Graphite electrodes are made of the highest quality petroleum coke and imported needle coke. They are widely used in electric arc furnaces and refining furnaces, and are suitable for the production of alloy steel and other metals, non-metals and other materials.

What are the Differences of the Electrodes for Submerged

Electrodes are divided into three types: carbon electrodes, graphite electrodes, and self-baking electrodes according to their use and production process. In submerged arc furnaces, self-baking electrodes are mainly used, but when producing ferroalloy products with lower carbon content, such as industrial silicon, graphite electrodes are required.
