METHOD FOR DEOXIDATION AND MICROALLOYING OF LOW-ALLOYED LOW-CARBON STEEL

摘要

The invention can be used in metallurgy in the production of low alloy mild steel. SUMMARY: The minimum amount of niobium microalloying for a suit is determined depending on the total carbon content, sulfur and phosphorus in the melt according to the formula: (% Nb) 0,04 + I (% C), (% S), (% P) 8K. where (% Nb) - minimum number of niobium microalloying required is for, in weight%: 1% C {) {5%) (% P) - the total content of carbon, sulfur and phosphorus in the melt before deoxidation.%;. By - experienced coefficient taking into account the absorption of niobium equal 0,85-0.95.
