  • Treatment Of Steel In Its Molten State (AREA)

Abstract

Procedeu de rafinare, anteturnare, a otelului prin tratare cu aliaje pe baza de nichel în oala de turnare, caracterizat prin aceea ca, în scopul realizarii unei purificari avansate chimice si structurale, i se adauga la presiunea atmosferica în proportie de 0,1...5% din greutatea topiturii metalice, un aliaj complet constituit din 25...75% Ni; 5...35% Si, 5...30% Mn, 2...30% Mg, 1,0...10% Al, 0,1...4% Ba si Fe rest sub forma de bulgari de 2...100 mm introduse în niste tuburi reactoare de sectiune variabila compartimentete în spatii de 0,2...2 dm3, pozitionate vertical si fixate de marginea oalei de turnare prin mijloace uzuale.Process for refining, annealing steel by treating with nickel-based alloys in the casting pot, characterized in that in order to achieve advanced chemical and structural purification, it is added to the atmospheric pressure in a proportion of 0.1. .5% of the metal melt weight, a complete alloy composed of 25 ... 75% Ni; 5 ... 35% Si, 5 ... 30% Mn, 2 ... 30% Mg, 1.0 ... 10% Al, 0.1 ... 4% Ba and Fe rest in the form of bulgars of 2 ... 100 mm inserted into some variable section reactor tubes compartmentalized in spaces of 0.2 ... 2 dm3, positioned vertically and fixed by the edge of the casting pot by usual means.
