とを特徴としている。[Means for resolving the problem] The continuous casting method of the present invention involves continuously supplying molten metal to a heated molten metal supply position on the surface of a roller-shaped base rotating in one direction, cooling it at a cooling position, and releasing the molten metal into the roller. It is a continuous casting method in which a metal or alloy is solidified on the surface of a roller-shaped substrate, and the heating temperature of the surface of the roller-shaped substrate at the molten metal supply position is set to one-third of the melting point of the metal or alloy or higher, that is, the melting point is T.
m, Tm/3°C or higher, and the angle formed with the vertical line passing through the center of rotation of the roller-shaped base is 3° to 3° in the opposite direction to the rotation direction.
The molten metal supply position is set at a position within the range of 45°, and the cooling position is set at a position where the angle formed with the vertical line passing through the rotation center of the roller-shaped base is within the range of 1° to 45° in the rotation direction. It is a feature.

とができない。[Function] In the continuous casting method of the present invention, the heating temperature of the surface of the roller-shaped base at the molten metal supply position is set to Tm/3° C. or higher. If the heating temperature is lower than Tm/3° C., the surface of the roller-shaped substrate is insufficiently heated and cooled rapidly, making it impossible to stably and continuously obtain a cast material having a unidirectionally solidified structure.
また、ローラ状基体の表面の加熱温度をＴｍ”Ｃ以上に
加熱すると、単結晶状の鋳造材を得ることができる。Further, by heating the surface of the roller-shaped substrate to a temperature higher than Tm''C, a single-crystal cast material can be obtained.

ることができることを見い出し、この発明をなすに至っ
たものである。As a result of repeated casting experiments with various changes in the molten metal supply position and cooling position on the surface of the roller-shaped substrate, this invention has been developed to find that the angle formed by the vertical line passing through the rotation center of the roller-shaped substrate is opposite to the rotation direction. Set the molten metal supply position at a position within the range of 3° to 45° in the direction of rotation, and 1° to 45° in the rotation direction.
By setting the cooling position at a position in the range of
The inventors have discovered that it is possible to continuously and stably cast a cast material having a unidirectional solidification structure, leading to the present invention.
溶湯供給位置を、回転方向と逆方向に３゛〜４５°の範
囲内に設定している理由は、３°未満であればブレーク
アウトが生じやすくなり、４５゜を越えれば一方向凝固
組織が乱れやすくなるためである。また冷却位置を１゜
〜４５°の範囲に設定している理由は、１°より小さく
なると一方向凝固組織が乱れやすくなり、４５°を越え
るとブレークアウトが生じゃすくなるからである。The reason why the molten metal supply position is set within the range of 3° to 45° in the opposite direction to the rotation direction is that if it is less than 3°, breakout will easily occur, and if it exceeds 45°, the unidirectional solidification structure will occur. This is because it becomes easily disturbed. Further, the reason why the cooling position is set in the range of 1° to 45° is that when the cooling position is smaller than 1°, the unidirectional solidification structure tends to be disturbed, and when it exceeds 45°, breakout is likely to occur.
また、ローラ状基体の表面は、鋳造する金属または合金

しい。たとえば、鋳造する金属がＡｆＬの場合、窒化珪
素、および黒鉛が好ましく、鋳造する金属がＣｕの場合
には、黒鉛、およびＭＯなどが好ましい。Further, the surface of the roller-shaped substrate is preferably formed of a material that does not have good wettability with the metal or alloy to be cast. For example, when the metal to be cast is AfL, silicon nitride and graphite are preferable, and when the metal to be cast is Cu, graphite, MO, etc. are preferable.
