摘要： In a rotary nozzle brick body formed into a substantially egg-like shape in it's plan view, the present invention secures a contact area of a nozzle portion and improves a configuration factor which considerably affecting the durability of the body. A rotary nozzle brick body is characterized in that the external shape in plan view is comprised of first circular portions (G), second circular portions (H), third circular portions (K), and tangent lines connecting the first circular portions and third circular portions so that a substantially elliptical shape is formed by increasing the circular portion and shortening the tangent lines, instead of a substantially egg-like shape having long tangent lines. Since the substantially elliptical shape is formed by reducing the linear portion of the brick body in it's plan view while the shape is expanded circularly, the contact area is maintained even if the sliding plate brick is rotated up to it's full-opened state, thereby eliminating a fear that molten steel or the like may leak.

摘要： When a molten steel flow velocity (u) on a bath surface is higher than a mold-powder entrainment critical flow velocity of 0.32 m/sec, the molten steel flow velocity (u) is controlled to a predetermined molten steel flow velocity by applying a shifting magnetic field to impart a braking force to a discharge flow from an immersion nozzle. When the molten steel flow velocity (u) is lower than an inclusion-adherence critical flow velocity of 0.20 m/sec and is higher than or equal to a bath-surface skinning critical flow velocity of 0.10 m/sec, the molten steel flow velocity (u) is control to the range of 0.20-0.32 m/sec by applying a shifting magnetic field to rotate the intra-mold molten steel in a horizontal direction. When the molten steel flow velocity (u) is lower than the inclusion-adherence critical flow velocity, the molten steel flow velocity (u) is controlled to the range of 0.20-0.32 m/sec by applying a shifting magnetic field to impart an accelerating force to the discharge flow from the immersion nozzle.

摘要： Molten steel is refined in a converter and is poured from the converter to a ladle. A ferro-alloy containing a component to be adjusted is added to the molten steel as needed. An amount of the alloy to be added to the molten steel in the ladle is calculated from a composition analysis value of the molten steel in the converter, and the amount of the alloy which is added when the molten steel is poured from the converter. The thus calculated amount of the alloy is added to the molten steel in the ladle. Electrodes are submerged in a slag layer on the molten steel so as to be arranged a predetermined distance from the molten steel. Power is supplied to the electrodes so as to generate electric arcs between the electrodes and the molten steel, thereby, arc-heating the molten steel. Simultaneously, a lance is submerged in the molten steel, and an Ar gas is injected in the molten steel therethrough, thus strirring the molten steel. Since deoxidation and composition adjustment of the molten steel can be simultaneously performed, processing time can be shortened.
摘要翻译： 熔炼钢在转炉中精炼，并从转炉浇注到钢包中。 根据需要将含有待调节成分的铁合金加入到钢水中。 根据转炉中的钢水的成分分析值和从转炉浇注钢水时所添加的合金量，计算钢包中钢水中添加的合金量。 将这样计算的合金量添加到钢包中的钢水中。 将电极浸没在钢水上的炉渣层中，以与钢水排列一定距离。 向电极供给电力，以在电极和钢水之间产生电弧，从而对钢水进行电弧加热。 同时，将喷枪淹没在钢水中，并且将Ar气体注入钢水中，从而使钢水分流。 由于可以同时进行钢水的脱氧和组成调整，因此可以缩短加工时间。
