する。) is exposed to high temperatures and frictional forces during rolling, so heat-resistant and wear-resistant alloys, such as 25% Cr-3% Ni, are used, but their lifespan is not sufficient and the quality of the rolled material is affected. It has a positive impact. For this reason, in the conventional method, the working surface of the guide shoe was not cooled, but since it comes into contact with the rolled material over a wide area during rolling, the cooling water does not reach the rolled material, which may result in undesired cooling of the rolled material and quality. had a negative impact on Another method has been to spray water directly onto the working surface of the guide shoe during idle time, but if a large amount of high-pressure water is used to increase the cooling effect, the working environment around the rolling mill deteriorates due to water spray. The present invention rectifies the above-mentioned drawbacks and cools the guide shoes over the entire surface during rolling and idle time from the back side without directly spraying water onto the working surface, and further uses the cooled cooling water to cool the rolling rolls. The purpose is to provide a cooling device for a guide shoe which is intended to be used in a guide shoe holder. The present invention is characterized in that a concave groove that closes further toward both rolling rolls is branched from the concave groove to form a water channel in cooperation with the back surface of the guide shoe.

又は配置方向は特定されるものではない。At this time, the material to be rolled 1 is held on the bus line by the guide shoes 4, 4', and at the same time its elongation in the circumferential direction is converted into the longitudinal direction. Guide shoes 4, 4' are
At this time, the conductive heat from the rolled material 1 and the frictional heat cause the material to reach a significantly high temperature, and the surface layer portion is likely to be peeled off by the frictional force. In the device of the present invention, the guide shoes 4 of the guide shoe holders 5, 5' that support and fix the guide shoes 4, 4' are
, 4' are provided with concave grooves 7 in the longitudinal direction thereof, and fishbone-shaped concave grooves 7' are carved toward the rolling rolls 2, 2' to form the bottom surface of the guide shoe. Together, they form a waterway, and pressurized water is passed through the introduction pipe 8 into the waterway to cool the back surface of the guide shoe. The concave groove 7 is cut by machining, and like a normal dovetail groove, its cross-sectional space is rectangular, and the depth of the groove is determined in relation to the wall thickness of the guide shoe. However, the cross-sectional shapes of the concave grooves 7 and the fishbone-shaped concave grooves 7' may have an appropriate curvature.
Further, the fishbone-shaped groove 7' is connected to the groove 7, but its direction is centered on the groove 7 and extends toward the side substantially perpendicular thereto, ie, toward the circumferential direction of the material 1 to be rolled. The fishbone grooves 7' are arranged in large numbers at regular intervals of 1 or more.The fishbone grooves 7' are shallower than the depth of the grooves 7 and It extends to the bottom end of the guide shoe holder 5, 5', and its opening part is connected to the rolling roll 2, 2.
′ directly corresponds to the island. That is, the guide shoe 4 is cooled by the cooling water flowing through this concave groove 7 and a large number of fishbone-shaped concave grooves 7' branching from it, and then this cooling water collides with the circumferential surfaces of the rolls 2, 2'. FIG. 2 is a plan view of the guide shoe holders 5, 5' of the present invention, and FIG. 3 is a side view of the same, with arrows indicating the flow of pressurized water. The guide shoe holders 5, 5' are provided with a clamp member 9 for fixing the guide shoe to the stereotactic layer, and are opened and closed by a cylinder 10.
Note that the present invention generally applies to piercers, elongates, IJ
The present invention can be applied to all inclined roll rolling mills that use guide shoes called -ra, and the shape or arrangement direction of the inclined rolls is not specified.
