Abstract: There is provided a continuous casting nozzle comprising a nozzle main body including a neck portion, a middle portion, and a lower portion, made of a refractory material having an inner bore through which molten metal flows, and a plurality of metal bars embedded along the longitudinal direction of the nozzle main body in at least one portion inside the refractory material forming the nozzle main body.

Abstract: A continuous casting nozzle for casting molten steel, wherein at least a surface layer of an inner bore of the continuous casting nozzle contacting with a molten steel is formed of a refractory comprising: an aggregate consisting essentially of alumina (Al2O3) or an aggregate comprising alumina (A12O3) as its main ingredient and melting point thereof being at least 1800 degree centigrade: from 15 to 60 wt. % and roseki as a balance. The refractory is added thermosetting resin as binder, kneaded, formed, and sintered in an anti-oxidizing atmosphere.

Abstract: A molten steel pouring nozzle comprising an upper nozzle made of a refractory, an upper end portion of which is to be inserted into a bottom wall of a molten steel receiving vessel; a lower nozzle made of a refractory, having, on an upper end portion thereof, a recess for receiving a lower end portion of the upper nozzle; and an open air shutoff means for preventing an open air from penetrating through an interface between the lower end portion of the upper nozzle and the recess of the lower nozzle.
