In this horizontal continuous casting facility 1, a continuous casting rod (welding rod) 3 cast through a water-cooled mold 2 is intermittently pulled out by a pinch roller 4.
The pinch rollers 4 are arranged one above the other with the welding rod 3 interposed therebetween, and by rotating while sandwiching the welding rod 3, the welding rod 3 is pulled out from the water-cooled mold 2 side, and both pinch rollers 4 are also provided. It is configured so that the sandwiching force (rolling down force) between them can be adjusted.

When manufacturing the welding rod 3 made of 31, W 4.5, C 1.1, and Co residual), the molten metal contained in the tundish in the horizontal continuous casting equipment 1 is cast through the water-cooled mold 2, and the pinch roller is used. 4 intermittently pulls out every predetermined length. As a result, the continuous casting rod 3 having a perfect circular cross section is pulled out from the water-cooled mold 2. Next, the continuous casting rod 3 is sandwiched by the pinch rollers 4 and pressed in the vertical direction by a predetermined pressing force, so that the continuous cast rods 3 are deformed into an elliptical cross section and pulled out from the pinch rollers 4. Subsequently, the continuous casting rod 3 is cooled by a cooling device (not shown), and is cut into a predetermined length by a cutting device to obtain a welding rod.

Has an elliptical cross-section, so by welding the part of the elliptical cross-sectional shape with a small radius of curvature toward the groove, it smoothly melts into the groove. In addition, the welding speed can be improved, the welding can be performed reliably and quickly, and it is hard to roll when placed on a flat surface and easy to handle. According to a second aspect of the present invention, in a method of manufacturing a welding rod, which continuously manufactures a welding rod by passing a molten metal through the inside of a mold, the pressing force of a pinch roller for pulling out the welding rod from the mold is adjusted. Since the welding rod deforms the cross-sectional shape of the welding rod, when the welding rod pulled out from the mold by the pinch roller passes through the pinch roller, the welding rod is pressed down by the pinch roller to produce a welding having a perfect circular cross section. By deforming the rod into an elliptical shape, a welding rod having an elliptical cross section can be easily manufactured.
