MOLTEN METAL POURING NOZZLE AND CONTINUOUS CASTING APPARATUS COMPRISING THE MOLTEN METAL POURING NOZZLE

摘要

PROBLEM TO BE SOLVED: To provide a molten metal pouring nozzle that can maintain a nozzle temperature during continuous casting and elongate the service life of a nozzle, and a continuous casting apparatus comprising the molten metal pouring nozzle.;SOLUTION: A molten metal pouring nozzle 1 is provided which comprises: a nozzle body 3 that surrounds a molten metal pouring passage 30 communicating with a storage space of a fireproof container 21 and has an inner surface 31 located facing the molten metal pouring passage 30 and an outer surface 32 located opposite to the inner surface 31; and a support seat 4 that supports the nozzle body 3 so as to wrap the outer surface 32 of the nozzle body 3 and mounted on the bottom of the fireproof container 21. The support seat 4 is so constituted as to have a first stainless cover 41 that constitutes the outer peripheral surface of the support seat 4, and heating unit 42 that can heat the nozzle body 3 via the outer surface 32, and a first refractory material 43 interposed between the heating unit 42 and the first stainless cover 41.;COPYRIGHT: (C)2015,JPO&INPIT
