Abstract
A cupola system for production of gray iron employs otherwise wasted heat to preheat fuel, pig iron, flux and compressed air fed into a melting furnace, by diversion of melting furnace exhaust-gases through a preheating furnace containing feeding conduits for the fuel, pig iron and flux, and for the compressed air; the preheating furnace is laterally inclined downwardly from a point of exhaust to a chimney, to the melting furnace; the diverting means includes a closed, downwardly concave reflecting top over the melting furnace, and the preheating furnace has a concave roof; an important provision of the invention is employment of a maximum number of conventional size and shape tuyeres in a radial array in the melting furnace.
