    • PURPOSE:To improve the quality and yield of a billet by providing a refractory sleeve which maintains the original shape until pouring ends to a nozzle inlet for pouring and disposing a sleeve with a gate having an aperture to the outside thereof. CONSTITUTION:The refractory sleeve 3 for forming a pouring basin is provided in the inlet of the pouring nozzle 5 in the bottom of a tundish 2. The refractory sleeve 4 with the gate having at least one aperture 5 in the lower part is further disposed to the outside of the sleeve 3. The inflow of the molten steel 9 poured from a ladle 1 into the tundish 1 to the pouring nozzle 6 is prevented until the required amt. of the pouring basin is formed. The intrusion of slag, etc. into the molten metal in the initial stage and the end stage of pouring is prevented and the billet having good quality is obtd. by the above-mentioned method. The amt. of the residual molten metalin the tundish 2 decreases and therefore the yield is improved.
    • 目的:通过提供一种保持原始形状的耐火套筒,直到倾倒端到喷嘴入口以提高其坯料的质量和产量,从而将具有孔的浇口套管向外部排出。 构成:用于形成浇注槽的耐火套3在中间包2的底部设置在倾倒嘴5的入口处。具有下部的至少一个孔5的浇口的耐火套4进一步设置在 套筒3的外侧。防止从浇包1向倾倒喷嘴6倾倒的钢水9的流入,直至所需的长度为止。 的浇注盆形成。 防止在初始阶段和浇注的最后阶段将熔渣等侵入熔融金属,并且可以获得质量好的钢坯。 通过上述方法。 amt。 的中间包2中的残留熔融金属的浓度降低,因此产率提高。
