摘要： PROBLEM TO BE SOLVED: To solve the problem that saw cutting cannot be done by wear and abrasion of a saw blade during a hot saw cutting step located on the downstream of a production line, for a steel product with a large section such as an extremely thick H-section steel or a highly strong steel product rapidly cooled after finish-rolling such as in TMCP specifications among section steels manufactured by hot rolling.
SOLUTION: When a long H-section steel 23 is cut in a widthwise direction at a predetermined longitudinal position of the H-section steel 23 while pushing it at a position in the vicinity of the predetermined position into two directions including a direction reverse to an advancing direction of a saw blade 18 and an upward direction, using the saw blade 18 advancing widthwise in the H-section steel 23 in a horizontal plane while turning, the H-section steel 23 is cut while independently controlling force of pushing in the two directions.

摘要： PROBLEM TO BE SOLVED: To easily adjust circumference of a spiral steel pipe while preventing defective offset of welding in the process of manufacturing the spiral steel pipe. SOLUTION: The inside circumference or the outside circumference in the portion which is formed into a pipe shape of the spiral steel pipe 7 in the middle of manufacturing is measured in a position which is just after welding. The variation of the inside circumference or the outside circumference on the basis of the measured value of the inside circumference or the outside circumference of the spiral steel pipe 7 is obtained. The spiral steel pipe 7 in the middle of the manufacturing just after internal welding is rotationally moved so that the inside circumference or the outside circumference of the spiral steel pipe 7 approaches the target value. At this time, the corrected angle to a steel strip 2 of the spiral steel pipe 7 is obtained from the variation of the outside circumference and the spiral steel pipe 7 is rotationally moved to the steel strip 2 by the corrected angle.
