Abstract
Invenţia se referă la producerea oţelului din materiale fiero-oxidate. Scopul invenţiei constă în sporirea economicităţii procesului. Instalaţia include un cuptor catalan de producere a fierului spongios unit cu un gazificator de topire şi un convertizor. În gazificatorul de topire, în care se produce gaz pentru cuptorul catalan, se încarcă o parte de fier spongios şi se obţine fontă lichidă. Cealaltă parte de fier spongios este încărcată în convertizorul alimentat cu metalul lichid obţinut în cubilou. În calitate de gaz pentru producerea metalului lichid în cubilou din deşeuri de metal şi coxă, se foloseşte un amestec de gaze provenite din cuptorul catalan, gazificatorul de topire şi convertizor. Dispozitivul prevede nişte rezervoare-tampon pentru oţel, care sunt amplasate între convertizor, cubilou şi gazificatorul de topire. Invenţia face posibilă sporirea economicităţii procesului şi utilizarea pe deplin a gazelor degajate.
