Conventionally, as a continuous casting device, as shown in FIG.
A method is known in which molten metal 4 is poured out and drawn out continuously while being cooled by a cooling mold 5 to produce an ingot 6 having a circular or similar cross section. In this case, if the solidification process of the molten metal on the inner wall surface of the cooling mold 5 is too long, sweating occurs on the surface of the ingot 6, causing rough skin. On the other hand, if the solidification process of the molten metal is too short, breakouts may occur.
鋳造する合金種によつて凝固温度範囲が異な
り、適正な鋳型の有効長さが変るので、鋳造する
合金種が決まれば、それに応じて鋳型の有効長さ
を変えてやる必要がある。 The solidification temperature range varies depending on the type of alloy to be cast, and the appropriate effective length of the mold changes, so once the type of alloy to be cast is determined, it is necessary to change the effective length of the mold accordingly.
鋳造する合金種の変更につれて、高価な鋳型全

It is uneconomical to replace the entire expensive mold as the type of alloy to be cast changes.
The present invention attempts to change the effective length of the mold relatively easily.

になつている。[Example] An example will be described based on the drawings. FIG. 1 is a longitudinal cross-sectional view, in which a heat insulating orifice plate 7 is applied to the opening of the heat insulating material 2 on the pouring side of the molten metal 4 of the molten metal sump 1, and the orifice 3 to pour out the molten metal. A cooling mold 5 is disposed surrounding the orifice plate 7. The cooling mold 5 has a cooling water introduction hole 8, and cooling water is introduced into the cooling mold 5, and the cooling water is blown out onto the casting surface from a cooling water nozzle 9.

The cylindrical portion 10 has a shape shown in the cross-sectional view shown in FIG.
and a flange portion 1 projecting from the outer periphery of the cylindrical portion 10.
1, the cylindrical part 10 is fitted into the cooling mold 5, and the flange part 11 is mounted between the cooling mold 5 and the wall surface of the heat insulating material 2.

にしてある。 Then, several types of heat insulating orifice plates 7 are prepared in which the thickness t of the cylindrical portion 10 is appropriately changed within the range of the wall length of the cooling mold 5, and these are assembled as appropriate depending on the type of alloy to be cast. By changing the mold length, the effective length of the cooling mold can be changed.

When the casting alloy type (for example, aluminum alloy, 6063, 6062, 5065, etc.) changes, the solidification temperature range changes and the effective mold length needs to be changed, but the present invention eliminates the need for expensive cooling mold equipment. The effective length of the mold can be easily changed by simply replacing the heat insulating orifice plate without replacing the entire mold.
