CONTINUOUS CASTING METHOD FOR CLAD INGOT

PURPOSE:To produce easily and continuously a clad ingot by joining the side faces of the ingots drawn from juxtaposed continuous casting devices to each other in the mid-way and remelting the joint part by arc welding, etc. to form a deposited metal part in the joint part. CONSTITUTION:Molten steels A, B consisting of different materials are supplied to the juxtaposed continuous casting devices 10, 11 and the ingots 12, 13 are drawn to a curved shape by pinch rolls 14 to join the side faces of the ingots 12, 13 to each other in the mid-way of drawing. The side face parts 12a, 13a of the ingots 12, 13 are remelted by an arc welding machine 15 in the joint position and a molten pool 16 and floating slag 23 are formed. The joined ingots 12, 13 are press-welded by rolling rolls 14a and the clad ingot 18 having the deposited metal layer 17 consisting of the different material is obtd. The continuous production of the clad ingot having high productivity is thus made possible.
