PURPOSE:To stabilize an operation by installing a casting mold in the direction where the flange surfaces of a blank contact with the respective roll bodies of a curved type continuous casting machine and disposing a single-hole immersion nozzle to the position corresponding to the flange center of the one side of the blank. CONSTITUTION:The continuous casting mold 1 is installed in the direction where the flange surfaces of the beam blank contact with the respective roll bodies of pinch rolls 5, 6 and roller aprons 4A, 4B. The single hole immersion nozzle 2 is disposed in the position corresponding to the center of the flange 1A on one side of the beam blank and a molten metal is poured from a tundish into the mold. The operation of the curved type continuous casting machine is thereby stabilized. |
