摘要： PURPOSE:To utilize the sensible heat of slag effectively, by placing charging material at high temp. on a transferring truck arranged on fixed skid beams, then by transferring the charging material to transferring skid beams. CONSTITUTION:Steel material is charged to a heating furnace while it is hot so as to reduce the fuel consumption and to prevent the flaw to be produced on the back surface of the material. That is, fixed skid beams 14 arranged in the range from the front of charging opening 16 to the discharging opening are moved freely in the longitudinal direction of the furnace between the moving skid beams 15 by a driving mechanism 25 by providing a moving truck 23. The moving skid beams 15 perform a series of vertical and horizontal movement, i.e., ascending, advancing, descending, and retreating. A table 38 received slag from a table 39 is lowered by an elevator 40 and transfers the slag on the group of trucks 23 located in the breadth of the table. The trucks 23 are put into the furnace by the driving mechanism 25 and the slag is transferred to the fixed skid beams arranged ahead by the operation of the moving skid beams 15. Repetition of these operation allows to supply the slag into the furnace.

摘要： PURPOSE:To contrive the improvement of thermal efficiency and the minimization of oxide scale to be generated, by introducing the exhaust heat of the soaking pit into the preheating furnace so as to permit the existence of either one or both of hot billet and cold billet correspondingly to the operational condition, and by continuously feeding these billets into the rolling process. CONSTITUTION:The exhaust heat of the soaking pit 10 is introduced into the preheating furnace 20 through the small flue 16. The cold billet 1A is charged into the preheating furnace 20 by the first pusher 30, and after being preheated, is pushed out onto the conveying roller table 44 by the second pusher 40, and is stopped at the side of the entrance of the soaking pit 10, and then, is dropped onto the transverse feeder 70 by the third pusher 50. In the meantime, the hot billet 1B sent from the billet forming process is laid parallelly to the cold billet 1A on the feeding roller table 60. Either one of cold billet 1A and hot billet 1B is stopped at the entrance of the soaking pit by actuating the transverse feeder 70. The pusher 80 is forced to contact with either one of billets, which is then pushed into the soaking pit 10. According to this method, the cold billet 1A is uniformly heated, and the generation of the oxide scale is minimized.
