본 발명은 생산성이 높은 연속열간압연을 행하기 위해 열간압연설비의 입구측에서 선행해서 반송되는 강편(2)의 후단부와 여기에 이어서 반송되는 후속의 강편(3)의 선단부와를 접촉시켜서 그 영역에서 강편(2)(3)의 두께방향으로 관통하는 교번자계(d)를 인가해서 가열하는 처리와 그 강편(2)(3)의 적어도 한쪽을 압압하는 처리와를 조합하므로서 강편(2)(3)끼리를 신속하고 또한 확실하게 접합하는 열간압연에 있어서의 강편의 접합방법 및 그 접합장치이다. A method and a device for joining billets, in which, for performing continuous hot rolling with high productivity, the rear end of a preceeding billet and the forward end of another following billet are brought into contact with each other at the inlet side of the hot rolling apparatus, and a heating process to impress an alternating magnetic field to the billets so as to pass through said billets in the direction of thickness thereof in a zone where the both billets are in contact with each other is combined with another process to press at least one of said billets, thereby enabling speedy and reliable joining of the both billets.
