Attempts have not been made to repel scum and other inclusions from the laminate-base metal molten interface using gas generated from a scum repellent during casting.

As shown in the figure, some of the repellent remains in the molten metal, gas is generated under the surface of the molten metal, and air bubbles are trapped on the surface of the laminate when it is cast. In the covered state, a solidified shell is formed; rt. As shown in this figure, NFC bubbles and the like trapped at the cladding interface are not eliminated even in the subsequent rolling process, causing poor adhesion and blowholes at the interface.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides that the n7'c bubbles generated from the scum repellent are not trapped at the cladding interface, but are generated at the fc interface. This provides a means for releasing the 'M'c bubbles from the interface and causing them to float.

上できるようにし几方法を提供するものである。In other words, in the conventional casting method, the cladding material is suspended vertically in the mold, so that the NFC bubbles generated on the surface of the cladding material are less likely to float up while remaining attached to the surface. According to the present invention, a scum repellent coated material is placed in a mold with an inclination of 10 to 300 mm/m relative to the vertical plane so that the surface coated with the scum repellent faces upward. The purpose of the present invention is to provide a method for easily separating and floating Ni bubbles generated at the cladding interface from the cladding interface.

To explain in detail, the present invention is a method for manufacturing a cast clad steel ingot, except that the cladding material is installed at an angle in the mold, and furthermore, the cladding material is cast while being vibrated. It is substantially the same as , and can be used here.

である。To further explain the characteristic configuration of the present invention, as shown in FIGS. 1(a) and 1(b), a composite material 2 coated with a scum repellent 1 on one side is placed in a mold 3. Vertical plane vp so that the surface is facing upward.
By suspending the steel ingot at an inclination of 10 to 300 mm/1 rL to the base plate 4 and pouring the base metal molten metal from the injection hole 5 of the base plate 4 in this state, a clad steel ingot with excellent interfacial adhesion is obtained. Note that FIG. 1(a) shows the case of obtaining a single-sided clad steel ingot, and FIG. 1(b) shows the case of obtaining a double-sided clad steel ingot.

らである。The installation angle of the cladding material 2 in the mold 3 is 10 to 300.
The reason why the slope is limited to m*/m is that the slope is lOmrz/
If it is less than 300mrtt/m, the effect of releasing and floating the bubbles generated on the surface of the laminate is small, and if it exceeds 300mrtt/m, although there is a bubble floating effect, the cladding ratio after rolling becomes uneven and the desired level cannot be achieved. This is because a clad steel ingot cannot be obtained.

ことができる。By suspending the laminate 2 at an angle in the mold 3 as described above, and by vibrating the laminate 2t during casting, air bubbles generated on the surface of the laminate can be more reliably separated from the surface of the laminate. It can be floated to the surface. This is because vibration can prevent air bubbles generated on the surface of the laminated material from adhering to the surface of the laminated material, and can also promote separation of air bubbles that have already adhered to the surface of the laminated material. Furthermore, even if undecomposed scum repellent remains on the surface of the laminate, this vibration can promote the decomposition of this residual scum repellent and prevent it from being injected into the cladding interface. .

う現象が生じる。また極端な場合には、鋳型３内から溶
湯が溢れることも起り得る。The appropriate magnitude of the vibration is a frequency of about 0.01 to 5 KHz and an amplitude of about 1 to 100 μ. If the vibration is too small, the effect of promoting bubble floating and decomposition on the repulsion side will be small; if the vibration is too large, splash will occur, and if the splash comes into contact with the repulsion agent, the repulsion agent will decompose before casting. In extreme cases, the molten metal may overflow from within the mold 3.
な、お、振動の方向としては、湯面に平行な方向が好ま
しく、合せ材の面に対して平行もしくは直角方向が選択
さルる。It should be noted that the direction of vibration is preferably parallel to the molten metal surface, and a direction parallel or perpendicular to the surface of the laminate is selected.

波振動子に限ら几ず、他の手段音用することもできる。As a means for vibrating the laminated material 2, an ultrasonic vibrator 7t can be used, for example, as shown in Figure WX1. In this case, for example, the head of the mating material 2 is formed to be approximately 3cIrL higher than the finished height of the casting, a hole 8 is drilled in this portion, and the vibrator 7t is attached to the head 1. By connecting the power source 9, the laminate material 2 can be vibrated via the vibrator 7. The portion above the hole 8 is not cast.
After blooming and rolling, it is excised as a crop. As mentioned above, the appropriate length of the portion above the hole is about 3 cIrL; if the hole is too long, there is a risk of crack propagation in the longitudinal direction, which is undesirable. The vibration means is not limited to the above-mentioned ultrasonic vibrator, but other means may also be used.
