Inductive melting in steelworks. by Mohamed Chaabet, Erwin Dötsch. After the development of induction technology with inverter outputs of over 40 MW for crucible furnaces with capacities of more than 65 t, the induction furnace offers itself as an alternative to the electric arc furnace.
Melting of large steel casting parts in the induction furnace. by Wolfgang Ertl, Erwin Dötsch. The voestalpine Group operates in their steel segment a foundry for the manufacture of heavy cast steel with a melt requirement from 1 to 200 t per casting.
The percentage of electric steel produced with electric arc furnaces as the traditional melting unit around the world (without China, an exceptional case with 90 % oxygen steel) is around 45 %, and this percentage is growing.
27 Δεκ 2013 · In this chapter, electric steelmaking is introduced with a short review: share, raw materials, operation, typical equipment, off-gas treatment, emissions. Electric-based steelmaking enjoys a...
This article discusses the most common methods of melting steels, namely, electric arc and induction melting. It describes the classification of refractories by an index of the “basicity” of the slag formed on the steel surface.
Melting iron, aluminium, steel, and other metals is done in these furnaces. The induction furnace, in comparison to most other methods of metal melting, provides a clean, energy-efficient, and well-controlled melting process. Electric furnaces use electricity as the principal heat source to melt and alloy metals and refractories at
Electric induction furnaces are employed for both non-ferrous and steel melting. The basis of this method of melting is to surround the metal in a crucible by a coil through which an alternating electric current passes. The current induced in the metal causes heating and melting and also creates a useful stirring action. Two salient
