THE EXPERIENCE OF THE INDUSTRIAL DEVELOPMENT OF STEEL 20A PRODUCTION TECHNOLOGY FOR THE HOT-ENHANCED CORROSION RESISTANCE AND COLD RESISTANCE SEAMLESS PIPES

Abstract

Experimental melting of the grade 20A steel during which desulfurization degree from 88 to 94% is reached, is carried out at ESPTs-2 of JSC «BMZ». The content of sulfur in teeming assay [S]82 = 0,0015% and correlation [Ca]/[S] =1,46 are reached at melting with application of «pure burden» and double induction of refining ladle slag.
