Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while S355J2W structural steel plate section steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of S355J2W structural steel plate section steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.
Is carbon steel 20#? Carbon steel means that alloy elements are not specially added into the steel, which is divided into ordinary carbon structural steel and high-quality carbon structural steel. The grades of ordinary carbon structural steel are Q195, Q215, Q235 and Q275. The grades of high quality carbon structural steels are: 10#, 20#, 45#, 15Mn, 20Mn, 25Mn, 30Mn, 35Mn, 40Mn, 45Mn, 65Mn, etc. It can be seen that S355J2W structural steel plate section, 20# steel is carbon steel, but carbon steel means more than 20# steel.
