| Ladle Refining Performance of Pulsating Mixing (PM) Process with 250-t BOF Melts Norio Sumita, Yukio Oguchi, Tetsuya Fujii, Toshihiko Emi, Arata Ueda, Takuo Imai |
|
Synopsis : Mass production test for the 250-t PM process was carried out on the commercial production line and the following results were obtained: (1) Stirring intensity of the melt is equal to or better than that of the RH degassing process. (2) The rate of deoxidization and yield of alloying elements are excellent, equivalent to those of the RH process. (3) The operation cost is one eighth that of the RH process. (4) The investment cost also is cheap and estimated to be one-fifth to one-tenth that of the RH process. |
