【Abstract】 The main technological measures of EAF steelmaking process to produce low nitrogen high strength shipbuilding steel plate were introuduced in No.1 steelmaking and rolling plant of Anyang Iron and Steel Group.The measures included higher hot metal ratio,slag foaming,endpoint carbon control and application of RBT process in EAF,atmosphere control,formation of good white slag and suberged arc operation in LF,and adoption of long ceramic nozzle and argon sealing between ladle and tundish to prevent against nitrogen pick-up in continuous casting.更多还原
