Melting furnace

Plant for melting metals and alloys based on iron, light metals and heavy metals. The energy required for melting is generated directly in the furnace.

Depending on the energy source, a distinction is made between electric furnaces (induction melting furnace (Fig. 1), electric arc furnace (Fig. 2), resistance furnace) and fuel-fired furnaces (coke and gas-fired furnaces, rarely oil-fired furnaces). The fuel-fired furnaces include the cupola furnace (Fig. 3, Küttner GmbH), the shaft melting furnace (Fig. 4) and the gas-fired stove and crucible furnace (Fig. 5).
