摘要： A continuous hot rolling method comprising the steps of: cutting the tail portion of a preceding material in a steel product and the front portion of a succeeding material in the steel product to form butt faces; previously determining the thickness of scale created on the butt faces to determine the proportion of the weight of the scale; calculating the amount of oxygen dissolved in a weld molten zone, determining a deoxidation capacity of a deoxidizer for deoxidizing the above amount of oxygen; allowing the butt faces to abut against each other to form a butt area; applying a laser beam to the butt area to form a weld molten zone; incorporating the deoxidizer having the above deoxidation capacity into the weld molten zone; and hot rolling the molten joined steel product.

摘要： PROBLEM TO BE SOLVED: To easily and precisely judge the joined condition and to enable the performance of smooth rolling operation by stretching the joined part with stretching stress corresponding to a load at the rolling time in the step before rolling and judging the joined condition with the stretch displacement quantity or the stretching stress. SOLUTION: After welding the rear end surface of a preceding steel material 1a and the front end surface of a succeeding steel material 1b with a welder 8, a clamp device 7b is shifted with a hydraulic cylinder 14 and the joined part is stretched with the setting load. The joined part is extended and the distance between the clamp devices 7a, 7b, is changed. This stretch displacement quantity is measured with a displacement detecting sensor and compared with a a displacement quantity which does not develop the breakage at the joined part in the preset rolling process, with an arithmetic device and it is judged whether the joined condition is acceplable or not. This judging result of the acceptance can be transmitted with a displaying device and an alarming device, and the necessary treatment can be executed.

摘要： PROBLEM TO BE SOLVED: To prevent a steel from being cut away during rolling by butting the rear end of an advance steel and the force end of a following steel, heating a joining part and the neighborhood to the temperature lower than an MnS melting temperature and heat-joining the joining part. SOLUTION: When a joining part is cooled, a molten S is not precipitated as MnS, it exists in the molten state, it thickens on the grain boundary face of a steel structure and the quality of material is made brittle. When the ratio of the highest temperature at the joining time and the MnS melting temperature is made higher than 1, the contraction value of area is made lower than 45%, it is made lower than the contraction value of area for requiring rolling and the danger of being cut away is caused. Accordingly, in order to roll in the stable state without causing breaking of the joining part, the ratio of the highest temperature and the MnS melting temperature is required lower than 1. That is, that the highest temperature of the joining part and the neighborhood (a part within 10mm from the joining part) is made lower than the MnS melting temperature is the necessary condition. The reduction in strength caused by the S brittleness is prevented, and the stable and continuous hot finish rolling is executed.
