furnace, and then from refractory walls to the charge. In a rotary furnace, the rotation enables the hot re-fractory to pass under the metal charge, thus trans-ferring heat more effectively from refractory to metal. As such, rotary furnaces have very high efficiencies (or "furnace factors") of up to ~90% (where furnace
2. Electric Arc Furnaces. An electric arc furnace (EAF) is a type of foundry furnace that is used to melt and refine metals, particularly scrap steel. The electric arc furnace uses electric arcs created by large graphite electrodes to melt the metal. The furnace is typically made of a large steel shell lined with refractory material, and the ...
Making the Furnace Body. Download Article. 1. Cut a steel garbage can with an angle grinder so it's 18 in (46 cm) tall. Look for a steel garbage can that's at least 18 inches (46 cm) tall and has a diameter of 16 inches (41 cm). If the garbage is taller than 18 inches (46 cm), put a metal-cutting blade on an angle grinder and turn it on.
