1. A method of preparing a continuous casting system for continuous casting of liquid metal to form a metal strand having a desired width, said method comprising:
selecting one type of flow diverter parts from at least two different types of flow diverter parts, each type of flow diverter parts corresponding to a different type of caster mold having a different width dimension; providing a partial submerged entry nozzle (SEN) for a continuous casting system comprising an inlet capable of receiving an incoming flow of molten steel from a tundish, a distribution zone, and a body having a bore, the SEN transitioning along the length of the body from a substantially circular geometry to a substantially rectangular geometry having opposing side walls and opposing front and back walls at said distribution zone; installing said selected type of flow diverter parts into the distribution zone of the partial SEN to assemble the SEN to provide in the distribution zone of the assembled SEN passageways for secondary flows formed at least partially by said flow diverter parts, wherein said flow diverter parts comprise at least a flow divider, a first diffuser, and a second diffuser, wherein said flow divider is installed upstream of said first diffuser and said second diffuser, and said flow diverter is configured to divide said liquid metal into a first stream and a second stream of liquid metal in said distribution zone, and wherein said first diffuser and said second diffuser are installed downstream of said flow diverter, said first diffuser is configured to further divide said first stream near a first exit port, and said second diffuser is configured to further divide said second stream near a second exit port; and installing said SEN between a tundish and a caster mold of a liquid metal continuous casting system such that said selected type of flow diverter parts provide desired flow characteristics for molten metal. |
