本発明は同一の溶鋼を分割槽を有するタンディツシュに
より夫々必要合金を添加して鋳造する方法に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of casting the same molten steel by adding necessary alloys to the same molten steel in a tundish having separate tanks.
従来から一般に行なわれている連続鋳造方法は取鍋内溶
鋼をタンディツシュを介して１個または複数個の鋳型に
注入するものであるが、この時タンディツシュや鋳型内
溶鋼に合金元素を添加することも種々提案されている。The conventional continuous casting method generally involves injecting molten steel in a ladle into one or more molds through a tundish, but at this time alloying elements may also be added to the tundish or molten steel in the mold. Various proposals have been made.
そして鋳型内に合金元素を添加する場合は、複数の鋳型
に夫々異なる成分の合金を添加することにより、同一の
溶鋼を用いて鋼種の異なる鋳片を製造したり、又は同一
成分の合金を用いて鋳型毎に添加合金量を調節したり、
溶鋼温度を制御することができる。When adding alloying elements to the mold, by adding alloys with different components to multiple molds, it is possible to manufacture slabs of different steel types using the same molten steel, or to manufacture slabs of different steel types using the same molten steel. to adjust the amount of alloy added for each mold,
Molten steel temperature can be controlled.
しかし、鋳型に合金成分を添加することは、鋳型内溶鋼
の温度が比較的低いこと、及び添加物の溶解時間が十分
に確保できず、添加物の鋳片内分布が不均一になりやす
いなどの難点がある。そこでタンディツシュへの合金添
加が有利となる。However, adding alloying ingredients to the mold requires that the temperature of the molten steel in the mold is relatively low, and that the melting time for the additives is insufficient, which tends to result in uneven distribution of the additives within the slab. There are some drawbacks. Therefore, it is advantageous to add alloys to tandish.

ものである。Traditionally, tanditshu that have been widely used are, for example, those disclosed in Japanese Patent Application Laid-Open No. 57-31,452 and Japanese Utility Model Publication No. 55-154,6.
There is one shown in No. 65. As shown in Fig. 2, molten steel is discharged from one ladle 1 through a ladle nozzle 2 into the center of a tundish 3, and then injected into a mold 5 from a pouring nozzle 4 provided at the bottom of the tundish. It is something to do.

造される鋳片は同一鋼種のものに限られ、異鋼種鋳片を
夫々の鋳型で鋳造することはできない。Conventional tundishes have the shape shown in Figure 2, so when molten steel is mixed in the tundish and alloys are added using alloy addition vibro, etc., the slabs cast in multiple molds/5.5 are the same. It is limited to steel types, and slabs of different steel types cannot be cast in separate molds.

鍋ノズルを複数個必要とし、これらに用いられる高価な
耐火物を多く必要とし経済的に得策でない。Another method of casting slabs of different steel types from molten steel in a single ladle using multiple molds is to place multiple tundishes on top of each mold and provide multiple nozzles in the ladle, so that each tundish is It is also conceivable to receive molten steel from separate nozzles and add the necessary alloying components to each tundish. However, this method requires a plurality of tundishes and ladle nozzles, and requires a large amount of expensive refractories used for these, which is not economically advisable.

方法はこれに反し、又複数のタンディツシュを用いるこ
とによる耐火物原単位の悪化を招く。Furthermore, in the above method, it is possible to pour molten steel into multiple tundishes by using one ladle nozzle and moving the position of the ladle as necessary, but it is possible to keep the molten steel surface of the tundishes as constant as possible during casting work. However, this method is contrary to this, and also causes deterioration of the refractory unit consumption due to the use of a plurality of tundishes.

、あるいは溶面下に吹込むこととしても良い。The above description is an example of the present invention, and it is also possible to adopt a method in which the molten steel supplied from the ladle nozzle is simply received at the upper part of the partition wall and flows into the divided tank 3-1.3-2 without providing a reservoir. Also, the tips of the alloy addition pipes 6-1 and 6-2 are connected to the 1st-(
It is best to position it facing the molten steel flow as shown,
In addition, it may be blown onto the molten steel surface or below the molten steel surface in the divided tundish 3-1, 3-2.
本発明はこのように構成されているので、１個の取鍋に

い。That is, in FIG. 1, the molten steel in the ladle 1 is poured into the sump 8, from where it is poured into the divided tank 3- through the spout 10.10.
1.3-2. At this time, necessary alloys are added to each molten steel stream using alloy addition pipes 6-1 and 6-2. Since the tundish 3 is divided by partition walls, molten steel does not mix with each other between the divided tanks.

を計ることができるものである。Therefore, by adding different alloys from the alloy addition pipes 6-1 and 6-2, slabs of different steel types can be cast. Furthermore, whether the alloy added from the alloy addition pipe 6-1.6-2 is of the same type or different type, by controlling the amount, the temperature of the molten steel in the divided tank can be adjusted and the quality can be improved. It is.
