| Abstract: | For S355J2G3 steel, requirements for the macrostructure is very strict. By means of increasing the purity degree of mohen steel, improving heat-insulating plate quality, controlling overheat degree, pouring speed, heat temperature and hold time for forging etc., the porosity is reduced greatly. |
