産業上の利用分野
本発明は冷間圧延鋼板等の材料となる薄鋳片を溶鋼から
直接製造する方法に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for directly producing thin slabs, which are used as materials for cold-rolled steel plates, etc., from molten steel.
従来の技術
一般に冷間圧延用材料としては連続鋳造で製造したスラ
グを熱間圧延ミルにより圧延したものが用いられている
。BACKGROUND OF THE INVENTION Generally, as a material for cold rolling, a material obtained by rolling slag produced by continuous casting using a hot rolling mill is used.
発明が解決しようとする問題点
しかしながら熱間圧延ミルが必要なため製造コストが嵩
むという問題があった。Problems to be Solved by the Invention However, since a hot rolling mill is required, there is a problem in that the manufacturing cost increases.
本発明は斯かる事情に鑑みてなされたもので、その目的
とするところは、熱間圧延ミルを用いることなく、溶鋼
から直接冷間圧延用の広幅薄鋳片を製造する方法を提供
しようとするものである。The present invention has been made in view of the above circumstances, and its purpose is to provide a method for manufacturing wide thin slabs for cold rolling directly from molten steel without using a hot rolling mill. It is something to do.
問題点を解決するための手段
本発明は、溶鋼内に浸漬され、溶鋼通過孔を加熱する加
熱機構を有する耐火物製モールドと、前記耐火物製モー
ルドに載置され前記溶鋼通過孔に連通ずると共に凝固殻
を生成する水冷機構を有する金屑性モールドとを備えた
鋳型により、アップキャストすることを特徴とする広幅
薄鋳片の製造方法である。Means for Solving the Problems The present invention provides a refractory mold that is immersed in molten steel and has a heating mechanism that heats the molten steel passage hole, and a refractory mold that is placed on the refractory mold and communicates with the molten steel passage hole. This method of manufacturing a wide thin slab is characterized in that upcasting is carried out using a mold equipped with a scrap metal mold having a water cooling mechanism for producing a solidified shell.
作 用
上記の如（構成されているから、加熱モールド及び水冷
モールドで幅方向に温度調節できるので安定して広幅の
鋼板を鋳造でき、鋳片は金属製モールド内で凝固する為
、広幅薄鋳片であっても１法精度や表面性状などもよく
することができる。Function As described above, the temperature can be controlled in the width direction with the heating mold and water cooling mold, so wide steel plates can be stably cast, and since the slab solidifies in the metal mold, wide and thin casting can be performed. Even if it is a piece, it is possible to improve the accuracy and surface quality of the single method.
鋳片を−Ｆ方へ引き−１−げるアップキャスト方式を採
用しているので、鋳片の自重によるテンションが生じな
いため、下方へ鋳込む場合の様にブレークアウトを起こ
ずことが無い。鋳込みは溶鋼の表面からでなく、内部か
ら行なうので、介在物の浮上分離除去も可能となり良質
の鋳片を得ることができる。Since we use an upcast method that pulls the slab in the -1 direction, there is no tension due to the slab's own weight, so there is no breakout that occurs when casting downward. . Since casting is carried out from the inside of the molten steel rather than from the surface, inclusions can be floated and removed, making it possible to obtain high-quality slabs.
