Description of the Prior Art In the continuous casting apparatus for thin metal strips described in French patent application FR 2,654,659, especially for continuous casting between two rolls or on one roll, the central part of the roll working surface is The roughness of both ends is larger than the roughness. The both end portions mean the outer peripheral area of the roll surface near the side end portions, and the central portion of the work surface means the outer peripheral area of the surface between the both end portions. This difference in roughness increases the driving force for the thin strip during casting. The difference in surface roughness between the end portions and the central portion is large. For example, the rough portion is formed by engraving the roll surface. Therefore, in this roll, the roughness changes discontinuously in the generatrix direction, and the following defects occur. That is, the discontinuity leaves a mark on the strip which locally weakens the strip and may tear along the mark. In this case, a narrow ribbon-like portion forms along the end of the strip, which becomes entangled and difficult to remove, causing the casting to stop.

This roll has two side edges 2, 3. The working surface 1 of the roll has some roughness or wrinkles, but this roughness is not constant. The roughness, measured by the standard factor R Z , is preferably 50-300 μm in the end zones 4, 5 close to the side edge parts 2, 3 and in the range 20-150 μm in the central zone 6. Preferably, for example, each is 150 μm and 80 μm. A feature of the roll of the present invention is that the roughness gradually and continuously changes along the generatrix of the roll. The parts A and A'of curve 7 show the roughness in the end areas. This roughness is greatest near the side edges of the roll and decreases regularly towards the value of section B of the curve corresponding to the central area of the roll.

に、本発明では粗さを規則的に変化させる。For a roll having a total working surface width of 800 mm, the length of the end zones is about 10 mm. The roughness is necessary for good contact between the roll and the thin strip during casting. Roughness needs to be increased to drive both ends of the strip well, but this results in discontinuities in the widthwise section of the strip, along which the strip breaks or ribbons on both sides. As a result, the strip cannot be taken out easily. In order to eliminate this drawback, the present invention changes the roughness regularly.

を生じさせる。In the present invention, roughness can be applied in various ways. In the first method, the roll surface is engraved (knur
ing) or rolling to give roughness. In this case, in order to change the roughness regularly, the engraving tool or rolling tool is moved along the work surface of the roll, and at the same time, the engraving or rolling pressure is gradually changed. That is, the pressure is increased in the end areas and then gradually reduced until finally to a low value corresponding to the roughness of the central area. Since the relationship between the desired roughness and the engraving pressure can be easily obtained by those skilled in the art, how to change the pressure can be easily determined by those skilled in the art. During engraving, the metal of the casting roll is pressed into the hollow groove to swell the material, thereby creating a protrusion on the roll.

とができる。If the initial generatrix is left straight, the outer diameter of the roll of the invention will be greater in the end areas than in the central area, so that the resulting strip will be thinner in the end areas than in the central area. Thus, in order to prevent the cross-sectional shape of the strip from deviating from the square, as shown in FIG. 3, the roll 8 is machined before engraving. That is, the central area of the roll 8 is cylindrical, its diameter is close to the desired final diameter value of the roll, and the end areas 9, 10 are slightly tapered. Therefore, the diameter near both end faces 11, 12 is smaller than the diameter of the working surface of the roll. After the engraving degree of both end areas is made larger than that of the central area, the diameter of the roll is almost constant over its entire width. Since the amount of protrusion caused by engraving can be easily calculated by those skilled in the art, the amount of taper to be applied to both end regions in order to obtain a roll having a constant diameter after engraving can be easily determined by those skilled in the art.

が好ましい。The second method is a method of roughening by machining to remove the cut portion. In order to roughen the surface of the cylinder 21 (FIG. 4), crossing turns or spiral grooves 20 (the axis of this spiral groove 20 being the same as the axis of the roll 21) are formed in this surface. Therefore, a series of valleys 23 and protrusions 24 are formed on the surface of the roll 21. The valleys 23 correspond to the bottoms of the grooves 20, and the protrusions 24 correspond to the joints of two adjacent spirals. The spiral groove 20 can be attached by lathe work by increasing the lead or feed of the tool. The lead of each rotation is a
The groove 20 has a depth h and the lead is larger than a a '
At this time, the depth of the groove 20 is h'which is larger than h. Therefore,
By changing the lead at the time of machining the surface of the roll 21, the roughness can be changed according to the depth of the groove 20. It is preferable that the lead be large in both end areas of the roll surface near the end on the roll side and small in the central area.
