Abstract
Metallurgical reactor for the production of cast iron, consisting of a metal casing internally lined, at least partially, with refractory material and provided, in the region of the top closure, with a duct through which high-temperature ferrous material is introduced, said reactor being equipped with a first series of lances for injecting the comburent gas, which are suitably directed and arranged on at least a first bottom level situated in the vicinity of the crucible for collecting the cast iron and through which, in association with a comburent gas, coal of suitable grain size is blown by means of a suitable carrier gas. Said duct has suitable cooling means and is provided, in the bottom terminal part, with nozzles for blowing in compressed gas. The middle zone of the casing of the reactor is lined internally with refractory material, pockets for receiving plates made of metal which is a good heat conductor being formed in said lining, said plates being provided on their side directed towards the outside of the reactor with heat exchanger means for cooling thereof.
