摘要： The invention relates to the iron and steel industry, more specifically, to continuous slab casting using a submerged nozzle. The inventive submerged nozzle comprises a bottom, lateral channels and a skirt which is secured to the lower part of the nozzle above the output lateral channels and is formed by two parallel flat surfaces which are gradually conjugated on the ends thereof by means of cylindrical surfaces. The nozzle is arranged in the center of the skirt and has two similar oppositely positioned lateral channels having a common longitudinal axis which forms together with the parallel flat surfaces of the skirt an acute angle ranging from 20 to 45°.

摘要： A nozzle for continuous casting of clean steel is capable of preventing adhesion of Al2O3-based inclusions to a wall surface of the inner hole of the nozzle while fully achieving an effect of a swirl vane. The swirl vane prevents drift in molten steel passing through the inner hole. The swirl vane is disposed in the inner hole. A wall surface is at least partly formed as a tubular-shaped refractory layer and is prepared by controlling a weight ratio of CaO/MgO and an apparent porosity to have a thickness of 3 to 20 mm, so as to prevent adhesion of Al2O3-based inclusions to the wall surface and the swirl vane while effectively maintaining the anti-drift effect for long hours. Further, inert gas is injected into a molten steel flow between an upper nozzle and the swirl vane to facilitate surfacing of Al2O3-based inclusions in a mold and reduce Al2O3-based inclusions in molten steel so as to achieve stable casting operation and high-quality steel with high cleanness.

摘要： Molten metal is introduced in a continuous-casting system downwardly into a mold through a nozzle opening downwardly into the mold at an axis to form in the mold a body of molten metal having an upper surface carrying impurities above the mouth of the mold. The body of molten metal is rotated about the axis in the mold. The nozzle is provided generally at the level of the upper surface of the body of molten metal with radially outwardly projecting vanes that prevent the body from rotating about the axis at the upper surface, thereby preventing inclusions from being sucked into the body of molten metal.

摘要： A refractory casting tube for a mould for continuously casting molten metal is provided with a top part (33) and a bottom part (35) which dips into the molten metal in the inner mould space (6) during the casting. A refractory deflection element (35) is integrated in the funnel-shaped or similarly shaped inlet (34) of the top part (33) and is shaped in such a manner that a fluid-dynamic dissipation is generated on the molten metal (21) during casting in said inlet (4, 34). The molten steel therefore flows into the mould roughly as a uniform flow with a homogeneous and stable distribution.

摘要： A refractory block configured to surround an outlet modifies, within a refractory vessel, the flow of molten metal passing through the outlet. The block takes the form of a base through which a main orifice passes, and a wall extending upwards around the periphery of the base. Structural features that may be included in the block include a circumferential lip around the exterior of the wall, an interior volume in which the radius decreases downwardly towards the main orifice in a plurality of steps, and flow openings in the wall that are configured to induce swirling in the flow pattern in the interior volume of the block.
