摘要： In a insert-type continuous casting nozzle comprising a highly functional layer formed to have a high corrosion resistance, a high anti-attachment capability, etc., and provided to defme an inner bore thereof, the present invention is directed to providing a refractory material (mortar) for an intermediate layer of the continuous casting nozzle, which has a property capable of fixing an inner bore-side layer to an outer periphery-side layer (a nozzle body) of the continuous casting nozzle, while preventing the occurrence of expansion splitting in the outer periphery-side layer due to a difference in thermal expansion between the inner bore-side and outer periphery-side layers, and a continuous casting nozzle using the refractory material for the intermediate layer. The refractory material for the intermediate layer contains a hollow refractory aggregate in an amount of 10 to 75 volume%, wherein a ratio of an average radius R of each particle of the aggregate to an average wall thickness t of the particle satisfies the following relation: R/t ≥ 10. This refractory material is disposed between an inner bore-side layer (2) and an outer periphery-side layer (3, 4) of a continuous casting nozzle.

摘要： [Problem ]
In a sliding nozzle comprising three plates consisting of an upper plate, an intermediate plate capable of a sliding movement, and a lower plate, it is intended to suppress adhesion and deposition of metal oxides and others on wall surfaces of inner bores of the three plates.
[Solution]
The intermediate plate has: a first inclined portion 2a whose surface defines a slidingly closing directional leading-side wall surface of an inner bore thereof and extends obliquely downwardly in a diametrically contracting direction; a second inclined portion 2b whose surface defines an upper part of a slidingly closing directional trailing-side wall surface of the inner bore thereof and extends obliquely downwardly in a diametrically contracting direction, and a third inclined portion 2c whose surface defines a lower part of the slidingly closing directional trailing-side wall surface of the inner bore thereof and extends obliquely downwardly in a diametrically expanding direction.

摘要： The present invention provides a flat immersion nozzle, wherein the immersion nozzle stabilizes the discharging flow of molten steel thereby stabilizing the molten steel surface in a mold, namely, decreasing the fluctuation thereof. In the present invention, in the immersion nozzle having a flat shape in which a width Wn of an inner hole is greater than a thickness Tn of the inner hole, a central protrusion portion (1) is disposed in a center section of a wall surface in a width direction of a flat section. Wp/Wn, a ratio of a length Wp of the central protrusion portion in the width direction to Wn, is 0.2 or more and 0.7 or less. The central protrusion portion (1) is disposed symmetrically as a pair; and a total length Tp in the thickness direction of the pair of the central protrusion portions is 0.15 or more and 0.75 or less of Tn.

摘要： The present invention provides a continuous casting method of molten metal using electromagnetic force to improve the cast slab surface properties and reduce the nonmetallic inclusions and bubbles trapped inside the cast slab. An alternating current is run through an electromagnetic coil 4 arranged around a casting mold 1 so as to surround a casting space 8 to control the meniscus shape to improve the cast slab surface properties, the discharge ports 6 of a submerged entry nozzle 5 are made upward oriented, and the direction of the discharge flow 14 from the discharge ports 6 is made one to above the intersection A of the casting mold short side and meniscus. Due to this, the nonmetallic inclusions and bubbles in the discharge flow are absorbed by the continuous casting mold flux of the meniscus 11 at the part of the meniscus reached. Further, the discharge flow 14 receives electromagnetic force due to the electromagnetic coil 4 whereby the spread of the discharge flow in the cast slab thickness direction is suppressed and the discharge flow 14 does not contact the long side shell 12, so it is possible to keep nonmetallic inclusions and bubbles from being trapped from the discharge flow 14 at the long side shell 12.
摘要翻译：本发明提供了一种使用电磁力的熔融金属的连续铸造方法，以改善铸坯表面性能并减少被铸造的板坯内的非金属夹杂物和气泡。交流电流穿过布置在铸模1周围的电磁线圈4，以围绕铸造空间8以控制弯月面形状以改善铸坯表面性能，使浸没式入口喷嘴5的排出口6向上并且从排出口6排出的排出流路14的方向形成在铸模短边和弯液面的交点A的上方。由此，排出流中的非金属夹杂物和气泡被弯月面部分的弯液面11的连续铸模熔剂吸收。此外，排出流14受到电磁线圈4的电磁力的影响，能够抑制铸坯厚度方向的排出流的扩散，排出流14不与长边壳体12接触，因此能够保持非金属夹杂物和气泡被从长侧壳12的排出流14捕获。
