摘要： A stable continuous hot rolling method which extremely lessens dislocation produced upon application of a high frequency induction heating of the transverse type for joining billets and eliminates plate breakage by individually cutting a rear end of a leading billet and a front end of a trailing billet by means of two pairs of cutting blades, one pair of which is arranged such that front faces of the blades are opposite in direction to each other on both sides of the billet and the other pair of which is arranged such that front faces of the blades are reversed in direction to those of the blades of the one pair, while conveying the respective billets in the same direction when the rear end of the leading billet and the front end of the trailing billet, respectively, are cut by means of drum shears which vertically interpose therebetween the rear end and the front end and are provided at outer peripheries thereon with cutting blades, and the respective ends are fed to a rolling mill to be continuously subjected to hot finished rolling after they are heated trough high frequency induction heating to be raised in temperature and pressed against each other to be joined.

摘要： This invention relates to a continuous hot rolling method having the steps of cutting off a rear end portion of a preceding metal piece and a front end portion of a subsequent metal piece, heating the resultant metal pieces, increasing the temperature thereof, bonding the two metal pieces together by pressing them, and then subjecting the metal pieces to finishing rolling. While the metal plates are heated, subjected to a temperature increasing operation and pressed, the region of each metal piece which is between a clamping portion thereof and the end portion thereof is restrained, whereby the deformation of the end portions (front and rear end portion) of the metal pieces is prevented.
