PURPOSE: A method for manufacturing alloy steel including Nb is provided to remove the need for increasing heating temperature for additional melting be melting an iron and niobium alloy block together with scrap. CONSTITUTION: A method for manufacturing alloy steel including Nb comprises the steps of: pulverizing and mixing niobium and iron(S10), melting the mixture of niobium and iron(S20), molding the molten alloy block into a block(S30), putting the alloy block into an electric furnace(S40), and melting the alloy block and scrap using an electric melting rod in the electric furnace(S50). |
