Secondary metallurgy is defined as the metallurgical work is done outside the primary metallurgical composition and temperature. Thus, the melting unit as well as the secondary unit can be specialized in their duty and design. Secondary metallurgy covers two main aspects, economy and quality.
The VAI FUCHS ladle furnace is of the “open type” in which are heating takes place under atmospheric pressure under an inert gas cover. Utilization of low impedance current conducting electrode arms with advantage of optimum energy input into the furnace applying the smallest possible electrode pitch circle.
