いる。(Prior art) Generally, when adding multiple types of additives such as inoculants to the molten metal carried into a ladle, these additives are deposited in the ladle in advance, and then the molten metal is poured into the ladle. In this case, it is said that it is desirable to set the deposition order of each additive to be deposited in the ladle in a predetermined order.
ところで、従来の技術として第２図に示す方法
があつた。 By the way, there is a method shown in FIG. 2 as a conventional technique.
即ち、取鍋１の上方にベルトコンベヤ２を配置

の上部から流下搬入させてなる方法があつた。 That is, a belt conveyor 2 is arranged above the ladle 1, and above the belt conveyor 2, a plurality of storage hoppers 3, 4, and 5 each containing a single type of additives A, B, and C are conveyed. The additives A, 5 are sequentially arranged in the direction of the
After letting a predetermined amount of additives a and c flow out onto the belt conveyor 2, the belt conveyor 2 is driven to
A and C are sequentially dropped and deposited in a mountain shape on the inner bottom of the ladle 1, and then the molten metal from the melting furnace 6 is poured into the ladle 1.
There was a method in which the water was carried down from the top.
（発明が解決しようとする問題点）
上記従来のものは、ベルトコンベヤ２から直接

１内にて規則正しく層状に堆積され難くなる欠点
があつた。(Problems to be Solved by the Invention) In the conventional system described above, additives A, B, and C are directly introduced into the ladle 1 from the belt conveyor 2. There was a drawback that as the time for adding additives (a) and (c) became longer, it became difficult for additives (a), (b), and (c) to be deposited in an orderly layer in the ladle (1).
即ち、添加剤ア，イ，ウはベルトコンベヤ２上
にその長手方向に間隔をおいて堆積されており、
しかもベルトコンベヤ２の速度は添加剤ア，イ，
ウの落下時の飛散を少なくするためにその速度を
所定値以下に低下させる必要がある。 That is, additives A, B, and C are deposited on the belt conveyor 2 at intervals in its longitudinal direction,
Moreover, the speed of belt conveyor 2 is
In order to reduce scattering when the cormorant falls, it is necessary to reduce its speed to a predetermined value or less.
また、ベルトコンベヤ２はその搬送終端部がプ
ーリ２ａに巻回しており、落下口部が拡開すると
ともに、ベルトコンベヤ２の放てき運動を受けな
がら各添加剤ア，イ，ウがベルトコンベヤ２から
徐徐に離脱することになり、落下時に分散し易く
なる。 In addition, the belt conveyor 2 has its transport end wound around a pulley 2a, and as the drop opening expands, each additive A, B, and It will gradually separate from the body, making it easier to disperse when it falls.
本発明は、上記欠点を解消した溶湯への添加剤
添加方法を得ることを目的とする。 The object of the present invention is to obtain a method for adding additives to molten metal that eliminates the above-mentioned drawbacks.
（問題点を解決するための手段）
本発明は、上記目的を達成するために、以下の
如く構成したものである。(Means for Solving the Problems) In order to achieve the above object, the present invention is configured as follows.
即ち、投入ホツパに複数種類の添加剤を順次層
状に堆積させ、前記投入ホツパを取鍋の上方に配
置するとともに、該投入ホツパの底面を開口して
前記取鍋内の添加剤を堆積順に自重落下させ、次
いで取鍋内に溶湯を搬入する構成にしたものであ
る。 That is, a plurality of types of additives are sequentially deposited in layers in an input hopper, and the input hopper is placed above a ladle, and the bottom of the input hopper is opened to deposit the additives in the ladle in the order in which they are deposited. The structure is such that the molten metal is dropped, and then the molten metal is carried into the ladle.
（作用）
本発明は上記構成にしたものであるから、投入
ホツパ内の各添加剤は、順次層状に堆積されるこ
とになる。(Function) Since the present invention has the above configuration, each additive in the input hopper is deposited in a layered manner.
そして、投入ホツパの底面を開口すれば、各添
加剤は、その自重により投入ホツパの底部に位置
するものから順次取鍋に向かつて落下し、該取鍋
内にて前記投入ホツパ内で堆積順序と同順序でも
つて堆積されることになる。 Then, when the bottom of the charging hopper is opened, each additive falls toward the ladle in order from the one located at the bottom of the charging hopper due to its own weight, and is deposited in the loading hopper in the ladle in the order in which it is deposited. They will be deposited in the same order.
