ラム外に放出させて薄帯とする方法である。The first method is usually called the single roll method, which uses the outer peripheral surface of a rotating roll as a cooling surface and continues to eject the molten material with the nozzle fixed, resulting in continuous rapid cooling and solidification. , Usually called the centrifugal quenching method, the inner circumferential surface of a rotating cylindrical drum is used as a cooling surface, and the molten metal is jetted onto the inner circumferential surface of the cylinder and is rapidly solidified while being in close contact with it due to centrifugal force. This method involves winding it up within a drum or peeling it off and releasing it outside the drum to form a thin ribbon.

出温度、噴出圧力。When producing a liquid quenched ribbon using these methods, the molten material is rapidly solidified on the surface of a rotary cooling body and formed into a ribbon. At that time, the quenched ribbon remains stuck to the surface of the rotating cooling body, and after running, the surface At an appropriate time determined by the adhesion force on the surface, the material peels off at an appropriate position on the circumferential surface of the cooling body, flies through the air, and then falls to the floor to be deposited or proceed to the subsequent winding process. . The magnitude of the adhesion force between the quenched ribbon and the rotary cooling body, whether amorphous or microcrystalline, is generally determined by the preheating temperature of the cooling body surface, the temperature change during ejection of molten material, the roughness of the surface of the material, Or ejection temperature and ejection pressure of molten material.

害となる。It changes and tends to fluctuate depending on various complicated factors such as the material and the differential pressure caused by the pressure gradient in the immediate vicinity on the surface of the rotary cooling body caused by the viscosity of the surrounding atmospheric gas covering the surface of the rotary cooling body. Therefore, while the rotary cooling body rotates, the ribbon does not peel off from its surface, but instead collides and deposits on the nozzle opening, damaging both the nozzle and the roll, causing trouble.

In such cases, the ribbon may bend and accumulate near the gas blowing nozzle opening, near the molten material jetting nozzle, or in the narrow gap between the cooling body surface and these nozzle openings. This will cause significant damage to the In addition, in the case of the second method, a release plate made of carbide, high-speed steel, beryllium copper, etc., which is relatively hard and does not cause seizures, is placed on the surface of the rotating cooling body that moves at high speed. It is installed with light contact or with a slight load applied, but depending on the operating conditions of the device, the adhesion force of the ribbon may exceed the peeling force of the method, in which case the ribbon may buckle. The thin strip is pressed between the release plate and the cooling body surface, and a satisfactory continuous ribbon cannot be obtained.
On the contrary, the surface of the cooling body will be seriously damaged.

入しようとしても、剥離板の反対側に冷却ロール。At the tip of the rapidly cooled continuous ribbon 5 formed on the outer peripheral surface of the cooling roll, the temperature rise of the cooling body is generally still small, so the adhesion force of the ribbon is small and it is naturally peeled off by centrifugal force.
When it reaches the release plate, it is ejected into the air, but as the subsequent molten material continues to spout, the surface temperature of the cooling roll 3 rises and the adhesion force increases, so that it adheres to the release plate. You will be able to reach it as it is. As shown in FIG. 7 (I3), the ribbon that has reached the peeling plate 1 has both sides facing the outer peripheral surface of the cooling roll 3 and the width of the blade surface 6 of the peeling plate facing it (

離して飛翔する。The jet stream ejected from the gas blowing nozzle, which is placed about /-~gwa away from the peeling plate, aims at this narrow gap 7 and passes through the gap 7, so it is blown away and cannot enter, and the direction is changed to the peeling plate. It continuously peels off and flies in a non-contact state along the lower edge of the object without receiving any damage.

来る。Even if the adhesion force of the ribbon to the cooling roll surface 9 is so great that a local part of the ribbon buckles and enters the narrow gap, the narrow gap 7 causes the ribbon to run immediately. The speed of the jet stream flowing in from the front of the gap is reduced.
Since it is easily blown away by O, it never enters continuously, and a continuous ribbon S can be produced safely.

ら徐々に離す方向に移動させることも可能である。Further, Fig. 10 shows a nozzle co' with a peeling plate l' which is provided by combining a peeling plate for preventing intrusion and changing the direction of the present invention and a nozzle for blowing gas, but in this case also. In principle, it is possible to prevent the continuous ribbon from entering in exactly the same way and to reliably peel it off. The release plate of the present invention has high hardness such as carbide, high-speed rigidity, high-density and high-strength nitride/silicon purple, silicon carbide 9-part stabilized zirconia, tetragonal boron nitride, alumina, etc.
A tough material with excellent wear resistance is used for the blade. or,
Any material can be used for the nozzle as long as it has appropriate rigidity, and the cross-sectional shape of the nozzle tip can be circular or oval as shown in Figure 2, or it can be a slit as in the case where it is integrated with a peeling plate. It may be in any form, and may be made of a suitable gas such as dry air, Ar gas, N
Any device may be used as long as it can flow out two gases etc. as a jet stream at an appropriate flow rate and pressure. Furthermore, in order to prevent the peeling plate of the present invention from coming into contact with the roll surface and damaging it due to the thermal expansion of the cooling roll due to the temperature rise near the surface of the cooling roll during spouting of the molten material, the peeling plate of the present invention is released slightly but gradually during ribbon production. It is also possible to move it in the direction.

た。The above experiment was repeated several times under different conditions within the range mentioned above, but the release plate was never caught, but either the release plate or the gas jet spray nozzle, or both, were removed. As a result of conducting an experiment under the same conditions, the higher the rotation speed and the lower the roll pressing load, the more the quenched ribbon and molten metal droplets stuck to the roll surface, causing the nozzle tip, peeling plate, etc. It was difficult to obtain a continuous ribbon due to buckling or accumulation near the gas blowing nozzle.

た。Example 3 In an apparatus as shown in Figure 5 (5) of the same principle, a metal drum having an inner diameter of about 7QQQ m and a cylindrical surface with a width of 70 cm on the inner circumference was rotated at goorpm and cooled. A molten metal spouting nozzle was placed on the inner peripheral surface at 13 left 0 position counterclockwise from the position directly above the drum, and 7 Ky Co75Fe5S was poured while filling the melting crucible with Ar gas.
After melting an alloy containing atomic percent of 15B15, Ar gas pressure is 0, K K9/Crl? Then, it was ejected onto the inner peripheral surface of the cooling drum through the narrow slit-like gap of the nozzle, and was rapidly cooled to produce an amorphous ribbon. At that time, as a peeling plate, a high-density, high-strength (analytical bending strength: rOK9/w'' degree) silicon carbide plate with length j; The tip has a flat blade shape, and a metal holder is installed near just above the inner circumferential surface of the cooling drum so that the gap with the inner circumferential surface of the cooling drum is Q, Q/ltl+, and the angle made with the tangent line is approximately 20°. Fixed arrangement, one side outer diameter / Aφ, inner diameter /
A nozzle made by crushing the tip of a φ copper pipe into an elliptical cross section is placed at a distance of J culm degrees from the direction that bisects the angle between the tangent to the cooling drum and the top surface of the peeling plate. By spraying Ar gas at a pressure of 0Ky/cm, a continuous amorphous ribbon with a width of SO, a length of about 100m, and a thickness of 3kpm was peeled off from the inner circumferential surface of the cooling drum. It was possible to produce the product without damage almost every time by reaching the temperature of 1~ with a vacuum adsorption type winding drum and winding it up.

If the peeling plate is strongly pressed with a force of about 2 Ky in an attempt to forcibly peel off the thin strip, the inner circumferential surface of the cooling drum may be damaged. The strong contact between the stripping plate and the peeling plate blade caused damage to the inner circumferential surface, significantly impeding the surface roughness of the back side of the ribbon, and having an adverse effect.
