装置に関するものである。Detailed Description of the Invention (Industrial Application Field) This invention is based on the quenching ribbon method, in which molten metal is continuously supplied from a supply nozzle onto a cooling body whose cooling surface is renewed and moved at high speed. When a cooling roll is used as a cooling body in a method for manufacturing a metal ribbon by quenching, the surface of a cooling roll for manufacturing a quenched ribbon can advantageously remove foreign substances attached to the surface of the cooling roll during actual operation. This invention relates to a cleaning device.

るものが多い。(Prior art) In recent years, a so-called quenched ribbon method for directly producing a ribbon from molten metal has been developed, and its research is actively being conducted. As disclosed, many of the techniques relate to reducing the entrainment of gas into the pool and improving the surface properties of the obtained ribbon.

At this point, when the circumferential speed is 15 m/s or less, air entrainment hardly becomes a problem.

Although air entrainment is hardly a problem, the tendency of polishing dust and splash from the cooling roll to adhere to the roll surface is not weakened, but rather becomes stronger due to the decrease in centrifugal force, which adversely affects the surface shape of the product. was.

(Quick cooling) W consisting of a rotating brush roll disposed around the outer periphery of a cooling roll to remove foreign matter adhering to the surface of the cooling roll.
This is a surface cleaning device for cooling rolls for band production.
（実施例） 以下、この発明の実施例について具体的に説明する。(Example) Examples of the present invention will be specifically described below.

5 is the quenched ribbon, and 6 is the brush roll.

いるスプラッシュ等の異物を除去するのである。As shown in the figure, the brush roll 6 is placed between the surface of the cooling roll 4 that has passed through the water pool 3 and before it enters the water pool 3 again, so as to remove the rotating splash that is attached to the roll surface. It removes foreign substances.
ブラシロール６の材質としては、銅もしくは銅合金（以

の鉄合金（以下単に鉄合金という）が有利に適合する。As the material for the brush roll 6, copper or a copper alloy (hereinafter simply referred to as copper alloy), or iron or an iron alloy such as stainless steel (hereinafter simply referred to as iron alloy) is advantageously suitable.

面が疵付くからであり、ここにクリアランスδは０．１
〜５．０ｍｍ程度とするのが好ましい。If a copper alloy brush roll is used, the tip of the brush may be placed in contact with the cooling roll, but if an iron alloy is used, there may be a gap between the tip of the brush and the roll surface as shown in Figure 2. It is necessary to use the clearance δ. This is because copper alloy is generally used as the cooling roll, and if a brush made of a material harder than copper comes into contact with it, the roll surface will be damaged, and the clearance δ is 0.1.
It is preferable to set it to about 5.0 mm.

。This is because if the clearance δ is smaller than 0.1 mm, there is a risk that the eccentricity of the brush roll or the limited accuracy of the length of the brush hair will cause the surface of the cooling roll to be rubbed during rotation, causing scratches on the surface of the roll. is large, and on the other hand, if it is larger than 5.01 square meters, the effect of removing deposits is almost lost.

移動するような状態で使用するのが望ましい。The direction of rotation of the brush roll is not particularly limited, but in order to enhance the effect of removing deposits, it is recommended to rotate the brush roll in the same direction as the cooling roll, and use it in a state where the brush roll moves in opposite directions at the closest position. is desirable.
さらに付着物の除去効率の向上のためには、ブラシロー
ルの配置個数は単一よりも複数の方が好ましい。Furthermore, in order to improve the efficiency of removing deposits, it is preferable to arrange a plurality of brush rolls rather than a single brush roll.

わけである。To explain the part shown in FIG. 3 in more detail, the brush roll 6a located farthest from the re-entry position of the sump is made of a hot metal such as stainless steel.3. The brush roll 6b is made of a heated alloy such as stainless steel and has a clearance of about 0.51, while the brush roll 6c closest to the re-entry position of the hot water pool is made of a prepared alloy. It is set so that it is in contact with the surface of the cooling roll.
