Abstract
The invention relates to an installation for melting pig-iron comprising a cupola furnace, a combustion chamber burning the waste gases leaving this cupola furnace. This installation comprises furthermore a heat exchanger between the flue gases leaving this combustion chamber and a thermodynamic fluid driving at least one rotary machine coupled to at least one electric generator, a superheating furnace for the pig-iron in the liquid state disposed between the cupola furnace and a casting station. This superheating furnace is supplied by said electric generator, and switching means for diverting a part of the electric energy of the electric generator towards user means, which permits, by simply adjusting the proportion of coke in the charge of the cupola furnace, to regulate the superheating temperature of the pig-iron leaving the cupola furnace to a value such that there is obtained a better overall economy derived, on the one hand, from the economy in the consumption of coke and, on the other hand, from the production of electric energy for other user means.
