Abstract
This invention rapidly and surely joins sheet bars to each other for continuously hot rolling in a high productivity by a combination of a treatment that the front end portion and the back end portion of these sheet bars are contacted and heated at such a contact region by applying alternating magnetic fields so as to pass in a thickness direction of the sheet bar with a treatment of pushing at least one of these sheet bars.
