Substantiation of an innovative concept of refining steel with out-of-burn treatment with the use of alkaline alumosilicate – pegmatite

Innovative technology ladle treatment steel processing with the use of a part of slag-forming mixtures of alkali aluminosilicates-pegmatite theoretically proved. The results of the Industrial development technology with the replacement of 50-80 % fluorspar by pegmatite were summarized and analyzed. The results of evaluation of the quality of the metal on non-metallic inclusions in accordance with GOST 1778-70 scales and ASTM E-45 (method A) confirm the effectiveness of the technology with partial or complete replacement of fl uorspar by pegmatite.
