<p>PROBLEM TO BE SOLVED: To raise the temperature of the atmosphere in a furnace body to the predetermined value in a short time, to uniformly heat a plate of a profile to be carried in the furnace body in a short time, and to carry it out of the furnace body. SOLUTION: In a device 10, plates 1 of the profile are carried in furnace bodies 12, 13,... by a carrying mechanism 31 from one side of a furnace body row 11 where a plurality of induction heating furnace bodies 12, 13,... are arranged on the line with intervals therebetween, and carried out from the other side thereof to heat the plates 1 in a substantially uniform manner. In a guide mechanism 21 of the device 10, one part is fixed to a carry-in side of the furnace body 13 substantially at the center of the furnace body row through the furnace bodies 12, 13,... of the furnace body row 11, and each end part on the carry-in side and the carry-out side of the furnace body row 11 is supported in an expandable manner in the carrying direction. The plates 1 are continuously carried so as to be successively pushed from behind by the carrying mechanism 31 via a guide mechanism 21.</p> |
