PURPOSE:To improve productivity in rolling operation by pouring a high-temp. molten steel into the space formed of the ends of preceding and succeeding billets and copper straps and cooling said steel to solidify on a heat resistant traveling belt then subjecting the billets to continuous rolling. CONSTITUTION:A clearance W is maintained between the high-temp. billets 1 and 2 on the heat resistant traveling belt 8 and the apertures on both sides in the transverse direction are closed by water-cooled copper straps. The molten steel 3 is poured from a vessel 7 for the molten steel into the space formed of the rear end of the preceding billet 1, the front end of the succeeding billet 2 and the copper straps. The vessel 7 is removed upon completion of pouring. The billets 1, 2 are transferred on the belt 8 and the molten metal 3 cools to solidify, thus forming a joint layer 4. The billets 1, 2 joined via the layer 4 are conducted to rolling rolls by the belt 8 and are successively rolled to a product. Since the joining is completed simply by pouring and cooling of the molten steel, the productivity in the rolling operation is improved. |
