Abstract: PURPOSE:To obtain a uniform joining force in the direction of a plate width and to conduct a steady continuous rolling by arranging at least two heating means along an abutting contact area, bringing each heating means under individual control and constraining temperature difference in each heating area within a specifying range. CONSTITUTION:The rear end part of a preceding billet and the front end part of a succeeding billet are cut by a cutting device, both billets are abutted in a contact state, then, an alternating field is applied by alternating field generating coils 10, 11 to a joining area to begin heating. At this time, the temperature at each heating area is measured by radiation thermometers 12-a, 12-b and heating is continued with the current controlled so that the difference of temperature between both thermometers is within 110 deg.C. In joining of billets, since the difference of deformation resistance at both end areas of the joined part is not so large to incline the joined surface or no gaps is made by welting down at the end areas on the side of high temperature, uniform joining force can be obtained in the width direction of the plate, consequently, an excellent joined surface can be obtained.
