ことが出来なかった。2. Description of the Related Art Conventionally, when a steel member such as iron is cast into an aluminum casting, the molten metal is poured into the cast metal member by directly contacting the surface of the cast metal member, and the cast member is cast. In this case, the molten metal poured into the mold sequentially fills the mold from a part of the mold to the whole. Therefore, the steel member placed in the mold is sequentially heated by the molten metal from a part thereof. Therefore, when the steel member has a cylindrical shape that is not easily distorted or has a thick wall, the steel member is less likely to be distorted by heat, and can be cast properly. However, when casting an iron plate with a wall thickness of 1 mm or less and a diameter of 50 mm or more so that one side is exposed on the surface of the casting, the molten aluminum alloy will touch one end of the iron plate and heat it at the same time. It was distorted and could not be cast flat.

た。SUMMARY OF THE INVENTION According to the present invention, a thin metal plate is cast flatly without distortion in a state where one side is in contact with a mold and the other side is fixed to an aluminum casting, and an iron plate is used. The task was to show a plan to make it in close contact with.

ととした。[Means for Solving the Problems] When molten metal is poured into a steel member, a gap is temporarily created between the molten metal and the steel member,
It was decided that heat would not be rapidly transferred to the steel material in this gap to prevent distortion due to heat, and then high pressure be applied to the molten metal to fill the gap at once with the molten metal to form a composite steel member.

間的に熱で歪んでしまうためであると思われる。[Operation] As described above, according to the conventional method, when a flat thin plate, for example, an iron plate having a wall thickness of 1 mm or less and a diameter of 50 mm or more is cast in an aluminum alloy molten metal, the steel plate is distorted and flat. Then I couldn't cast it. One of the causes is that the shape of a thin flat plate is easily deformed, and the other is that the molten aluminum alloy touches from one end of the iron plate for a short time and only one side sequentially, so the iron plate is momentary. It seems that it is distorted by heat.

つ鉄板の片面を露出させた状態に複合化することが出来
たのである。Therefore, in the present invention, the molten aluminum alloy is brought into contact with the entire one surface of the iron plate at the same time, and the molten metal is solidified while pressing the iron plate against the die surface. Therefore, the iron plate could be composited without being distorted in a state in which the iron plate was in close contact with the molten aluminum alloy and one side of the iron plate was exposed.

る。First, the iron plate set in the mold is covered with a heat insulating material. When the molten aluminum alloy is poured into this mold, the molten metal covers the heat insulating material, but due to the surface tension of the molten metal, it does not enter the gap in the heat insulating material. Therefore, a gap is created between the iron plate and the molten aluminum alloy. This gap is composed of the heat insulating material and the gas phase, and prevents the heat of the molten aluminum alloy from being rapidly transferred to the iron plate. Next, as soon as the molten aluminum alloy is filled in the mold, a high pressure is immediately applied to the molten metal to allow the molten metal to permeate into the gaps created by the heat insulating material and the gaps inside the heat insulating material at the same time. It is wetted with the molten metal, and the iron plate is pressed against the mold surface and solidified and adhered as it is.

合化される。By doing so, the entire surface of the iron plate is brought into contact with the molten aluminum alloy at once, and is heated, so that the layer of the low melting point alloy or the like on the surface of the iron plate is welded to the aluminum alloy. In this way, one side of the iron plate is fused with the molten aluminum alloy to become one,
The other surface is compounded into an exposed form on the surface of the aluminum alloy casting.

材の層を押しつぶしたあとに、１ミリ以下のごく薄い隙
間が出来ればよい。Further, the thickness of the gap between the iron plate and the molten aluminum alloy produced by the heat insulating material is such that the conductive heat that the iron plate receives from the molten metal for a short time until the molten metal is filled in the mold and high pressure is applied to the molten metal. The thickness should be such that the heat insulation effect is maintained so that it does not distort severely. In reality, it is sufficient if a very thin gap of 1 mm or less is formed after the molten aluminum alloy crushes the heat insulating material layer.

差によって剥離するのを防ぐこともできる。Further, the layer of the heat insulating material to which a high pressure is applied and the molten aluminum alloy permeates to form a composite becomes a composite material with the aluminum alloy. The coefficient of thermal expansion of this composite material is smaller than that of the aluminum alloy when the material of the heat insulating material has a coefficient of thermal expansion smaller than that of the aluminum alloy. Therefore, to obtain a thermal expansion coefficient close to that of the composite steel member,
If the type of heat insulating material is selected and used, it is possible to prevent the steel member from peeling off due to the difference in thermal expansion coefficient.
