MIX FOR DEOXIDIZING AND MODIFYING STEEL Russian patent published in 2004 - IPC

Abstract RU 2231571 C1

FIELD: ferrous metallurgy.

SUBSTANCE: mix based on aluminum/magnesium/calcium alloy further contains 10-50% rare-earth metals, 5-20% low-phosphorus magnesium-containing oxide material, and 5-10% rare-earth metal fluorides. Peculiar feature of invention consists in that, as rare-earth metal oxides and fluorides, Polirite (abrasive) and Polirite waste are utilized.

EFFECT: enhanced reducibility and modifying ability of alloying elements, increased desulfurization, and improved quality of steel.
