Abstract
The invention discloses steel being low in raw material cost. The steel comprises the following raw material components in percentage by weight: not more than 0.235% of carbon, not more than 0.57% of cerium, not more than 0.389% of silicon, not more than 0.027% of phosphorus, not more than 1.13% of manganese, not more than 0.035% of titanium, not more than 0.0145% of surplus, and the balance of iron and impurities. A converter steelmaking craft is adopted during a smelting process of the steel; firebricks are arranged on the inner wall of a converter; a plurality of holes are formed in the side wall of the converter; and through the holes, air is blown into the converter for side-blown converter steelmaking. By adoption of the above technical scheme, the steel disclosed by the invention has the advantages that the adopted raw materials are wide in source, so that the consumption of precious metal can be effectively reduced, the whole cost can be reasonably controlled, and a lot of cost can be saved for an enterprise; and accordingly, large-scale popularization and application are facilitated.
