METHOD OF ALLOYING AND MICROALLOYING OF LOW-ALLOYED LOW-CARBON STEEL Russian patent published in 1997 - IPC

Abstract RU 2095426 C1

FIELD: ferrous metallurgy. SUBSTANCE: method includes sampling before deoxidation, determining carbon content in sample, introducing niobium and manganese into smelt, amount of niobium depending on carbon content and being determined from equation: [wt%Nb] = 2.5 x 10-3/[wt%C]. Amount of manganese depends on carbon content and amount of niobium introduced: [wt%Mn] = 9.5 x 10-3/[wt%C]+[wt%Nb] where [wt%Mn] is minimum amount of manganese added. EFFECT: optimized alloying process. 2 tbl
