At present, attempts are being made to develop various continuous casting and rolling methods. The common ideas for these are: ■ To produce a product using the minimum necessary force, and for that purpose, to cast a thinner or thinner slab at a higher speed; In order to respond to the formalization of product composition in the form of low-volume production of different products,
Being able to produce small quantities efficiently, and for that purpose,
For example, the equipment must be compact.

Moreover, the fact that the equipment is more compact than other continuous casting and rolling methods satisfies these requirements.

うな方法では鉄鋼を対象とした場合次のような問題点が
ある。By the way, in the D1 method as a conventional copper roughing fa manufacturing method, for example, as disclosed in Japanese Patent Publication No. 46-643, the core material (copper wire) is introduced through a nozzle provided at the bottom of the crucible. However, this method has the following problems when targeting steel.
■≦４のように高融点金属の場合には、芯材導入部とな

芯材の浸漬方法に関するものである。(Means for solving the problem) The inventor is D? After conducting various studies to apply the method to the steel industry, it was discovered that the method could not be applied to steel without some improvements to the conventional manufacturing method for copper wire. The present invention relates to one such method, which is a method for dipping a core material.

満足することを特徴とするものである。The immersion method of the core material in the present invention is basically that the core material is introduced from the top of the molten steel surface and immersed in the molten steel, as opposed to the conventional introduction from the bottom of the crucible. It is characterized by satisfying the following structural requirements in addition to the above method:

検討した。What is important in common with these is to control the adhesion of the solution to a predetermined value, and to do this, it is necessary to control the time that the core material stays in the solution, that is, the immersion time, to a predetermined value. becomes. Normally, in such a process, it is undesirable to change the line speed because it affects other processes, and the pass line of the core material is kept constant, and the distance that the core material passes through the solution, that is, the immersion distance, is always constant. It is necessary. In the Metsuki line, a zinc roll is installed in the solution so that the solution passes through a certain pass line, but in the case of the D11 method, the solution to be immersed is very high temperature molten steel, so the zinc roll described above is used. It is very difficult to install such a guide roll in the melting tower, and it is necessary to pass the core material between two points above the melting tower with a constant pass line; A method will be adopted in which the steel is immersed in molten steel. That is, the above 2
A predetermined curvature is given to the core material to make it curve by inserting an IC between the points,
As a result, the core material is immersed in a 2-volume solution, and as a method for imparting a predetermined curvature to the core material, the following two methods were first investigated.
■２点間の距離を十分大きくとり、その間で芯材が自重
により撓むことにより生ずる曲率を利用する方法。■A method in which the distance between two points is set sufficiently large and the curvature created when the core material bends due to its own weight is used.

座屈せしめて撓ませること；てよシ生ずる曲率な列用す
る方法。0. A method in which the core material is held at two support points and the core material is buckled and flexed between them; a method that uses a curvature row that causes a twist.
しかし、Ｄｒ法の浸漬方法として前記２つの方法を用い
た場合には以下の問題が生ずることが判明した。However, it has been found that when the above two methods are used as the Dr method immersion method, the following problems occur.

ｊ！ｉであシ、浸漬深さも浅くならざるを・ｉτ婆ない
。その為、溶鋼湯面レベルのわずかな変動により浸漬距
雅が著しく変動しやすいという欠点を有している。The former method makes use of its own weight in the atmosphere: The core material passing between two points is always due to its own weight (and it is possible to pass through a path line with a constant curvature, but only a part of it When the steel is immersed in molten steel, the difference in specific gravity between the core material and the molten steel becomes very small, so the self-weight that causes curvature is almost eliminated, and as a result, the steel tends to float to the surface of the molten steel. The curvature obtained by this method usually has a very large j!i, and the immersion depth must also be shallow.Therefore, the immersion distance is likely to vary significantly due to slight changes in the molten steel surface level. It has the following drawbacks.

ずる。Furthermore, in the case of the latter, which forcibly bends the core material, the curvature can be made much smaller. Although it is an advantageous method,
In this case as well, when the core material is immersed in the bath A, the material strength of the core material decreases significantly and the stiffness: j decreases. As a result of 2×1τ caused by a large floating blade in the portion, the same problem as in the former case occurs.
そこで本発明は、芯材に曲率を与える方法とし定したパ
スラインの確保を可能としたものである。Therefore, the present invention is a method of imparting curvature to the core material, making it possible to secure a defined pass line.
なお、図中（３）は♂鋼保持炉、（４）は芯材送出装置
、（５）は冷却装置である。In the figure, (3) is a male steel holding furnace, (4) is a core material delivery device, and (5) is a cooling device.

較的小さな曲率でも安定したパスラインを確保でき、し
かも丸棒のように比較的剛性の大きな形状の芯材に対し
ても容易にかつ安定して曲げ変形を与えることができる
のである。以下、具体例を用いて更に詳細に説明する。In other words, by imparting curvature to the core material using the method described above, a stable pass line can be secured even with a relatively small curvature, and it is also possible to easily and stably create a core material with a relatively large shape such as a round bar. This allows bending deformation to be applied. A more detailed explanation will be given below using specific examples.
先ず、従来法のように溶鋼保持炉（３）底部からの芯材
（２）導入が鋼においても可能か否かを確認すべく第２
図に示すような装置を用いて実験を行った。First, in order to confirm whether it is possible to introduce the core material (2) from the bottom of the molten steel holding furnace (3) as in the conventional method, a second
Experiments were conducted using the apparatus shown in the figure.
なお、溶鋼保持炉（３）の底部にはブツシュ部材（６）

材質は従来法と同様に勘合金とした。Note that there is a bushing member (6) at the bottom of the molten steel holding furnace (3).
The inlet was made of a refractory material known as a metal alloy, as in the conventional method.

適用することは非常に困賭であることが確認できた。3450 class molten steel (7) was put into the molten steel holding furnace (J and kept at 1520°C.) A wire rod of the same material was introduced from the bottom and immersed in it. Molten steel (7) began to leak from the bottom due to wear of the core material (2).Furthermore, when the core material (2) was made into a plate shape, factors such as meandering were added and the bushing member (6) by Miyako was added. ) wear became even more noticeable, and it was confirmed that it would be extremely difficult to apply it to actual operations.
次に、上部からの浸漬方法について検討を行ったＯ
先ず、芯材を溶鋼中に浸漬させるに必要な曲率を与える
方法として、芯材自身の自重を利用する方法では、この
場合に得られる曲率は一般に非常に大きな値となるため
浸漬深さが非常に浅くなシ、従って炉長を非常に長くし
なければならない。加えて、芯材が溶鋼中に浸漬した場
合の問題については先に述べた通シである。Next, we investigated the method of immersing the core material from above. is generally a very large value, so the immersion depth must be very shallow, and the furnace length must therefore be very long. In addition, the problem when the core material is immersed in molten steel is the same as mentioned above.
また、強制的に座屈させる方法についても本質的な解決
に至らないのは前述の通シである。Furthermore, the above-mentioned method of forcibly buckling does not provide a fundamental solution.

A core niobium delivery system (4) with a pending mechanism is placed on the immersion input side, and 2L2 is applied to the molten steel (7) in the molten steel holding furnace (3) while giving a bending deformation of 1500 mm to a 3-chicken thick steel plate.
As a result, since the curvature has already been given by ff1 (a deformation n), even if it is immersed in molten steel (7), it will not try to return to its original shape as in the method explained earlier, and a stable pass line will be created. was ensured, and a good slab shape was stably obtained.Furthermore, even if the plate thickness and shape of the core material (2) changed, a predetermined curvature could always be stably imparted.
