KW  -Submerged Entry Nozzle (SEN)
AB  - Submerged Entry Nozzle (SEN) is a type of ceramic or composite tube. This tube used in continuous casting machines is installed between the reservoir (tundish) and the copper mold. The main function of this tube is not only deliver and control the flow direction of liquid steel into the mold but also to protect reoxidation of liquid steel during transfer from the tundish into the copper mold. In general, SEN should be durable and stable at high temperatures during long sequence continuous casting. One important factor on life time of SEN during operation is by preheating of the SEN itself. In this research, effects of preheating temperature and preheating time of different commercial SEN grades are taken into consideration. To observe the corrosion behavior and life time of the SEN during continuous casting, each preheated SEN is installed in a real plant during casting of various liquid steel grades. Results of this study can be used to select a suitable preheating condition of the SEN to minimize any trouble for long sequence of continuous casting process of steel.
