止させる原因となる。BACKGROUND OF THE INVENTION In the continuous casting apparatus for thin metal strips described in patent application FR-A-2,654,659, in particular for continuous casting between two rolls or on one roll, the central part of the working surface of the roll is known. The roughness at both ends is made larger than the roughness. In addition, both end parts mean the outer peripheral area of the roll surface near the side end part, and the central part of the work surface means the outer peripheral area of the surface between the above-mentioned both end parts. This different roughness increases the driving force of the thin strip during casting. The difference in surface roughness between the end portions and the central portion is large. For example, the rough portions are made by engraving the roll surface. Therefore, in this roll, since the roughness changes discontinuously in the generatrix direction, the following defects occur. That is, traces remain on the strip in the discontinuous areas, which weaken the strip locally and along which the strip may tear. In this case, a narrow ribbon-like portion is formed along the end of the strip, which entangles and is difficult to remove, causing a halt in casting.

This roll has two side ends 2,3. The work surface 1 of the roll has some roughness or wrinkles, but this roughness is not constant. Standard factor R Z roughness measured in is preferably from 50 to 300 [mu] m in both ends sections 4 and 5 near the side edge parts 2, and even in the range of the central region 6 20 to 150 [mu] m Preferably, for example, each is 150 μm and 80 μm. The feature of the roll of the present invention is that the roughness gradually changes continuously along the roll generatrix. The parts A and A 'of the curve 7 show the roughness in the end regions. This roughness is greatest near the side edges of the roll and decreases regularly towards the value of the part 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。[0007] For a roll having a total working surface width of 800 mm, the length of the end sections is about 10 mm. Such roughness is necessary for good contact between the roll and the thin strip during casting. It is necessary to increase the roughness in order to drive the both ends of the strip well, but then the width of the strip becomes discontinuous, and the strip breaks along the discontinuity or the ribbon on both sides. As a result, inconvenience occurs in strip removal. In order to eliminate this drawback, the present invention changes the roughness regularly.

を生じさせる。In the present invention, the roughness can be applied in various ways. In the first method, the surface of the roll is engraved (knur
ing) or rolling to provide roughness. In this case, in order to change the roughness regularly, the engraving tool or the rolling tool is moved along the work surface of the roll, and simultaneously the engraving or rolling pressure is gradually changed. That is, the pressure is increased in the end zones, then gradually reduced, and finally to a lower value corresponding to the roughness of the central zone. Since the relationship between the desired roughness and the engraving pressure can be easily determined by those skilled in the art, it is easy for those skilled in the art to determine how to change the pressure. During engraving, the casting roll metal is pressed into the hollow grooves to expand the material, thereby producing protrusions on the roll.

とができる。[0009] If the initial generatrix is straight, the outer diameter of the roll of the present invention will be greater in the end regions than in the center region, so that the resulting strip will be thinner at both ends than at the center. In order to prevent the cross-sectional shape of the strip from deviating from the square, the roll 8 is machined before engraving as shown in FIG. That is, the central area of the roll 8 is cylindrical, its diameter being close to the desired final diameter value of the roll, and the end areas 9, 10 are slightly tapered. Therefore, the diameter near the end faces 11, 12 is smaller than the diameter of the work surface of the roll. After the engraving degree in the end sections is greater than in the center section, the diameter of the roll is substantially constant over its entire width. Since the amount of protrusion caused by engraving can be easily calculated by a person skilled in the art, the amount of taper applied to the end sections 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。A second method is a method of roughening by machining to remove a cut portion. In order to roughen the surface of the cylinder 21 (FIG. 4), intersecting turns or spiral grooves 20 (the axis of the spiral groove 20 is the same as the axis of the roll 21) are formed on the surface. Therefore, a series of valleys 23 and projections 24 are formed on the surface of the roll 21. The valley 23 corresponds to the bottom of the groove 20, and the protrusion 24 corresponds to the joint of two adjacent spirals. The helical groove 20 can be provided in a lathe operation by increasing the lead or feed of the tool. The lead of each rotation is a
The groove 20 at the time of is a depth h and the lead is larger than a '.
In this case, the depth of the groove 20 is h 'which is larger than h. Therefore,
By changing the lead of the surface of the roll 21 at the time of machining, the roughness can be changed according to the depth of the groove 20. Preferably, the leads are large in both end areas of the roll surface near the roll side end, and small in the center area.
