PROBLEM TO BE SOLVED: To provide a supplying device in a casting metal furnace for forming a uniform casting product by making the mixed proportion of a casting ingot and a return material approximately constant. SOLUTION: A runner part (return material) being cut with a trimming press 5 is automatically supplied to a bucket 20. An ingot cutting device 8 cuts the ingot into 1/3 according to the operational number of a casting machine 2, and supplies it to the bucket 20. When the operational number of the casting machine 2 reaches a given number, a bucket moving means 21 raise the bucket 20, so as to insert the return material supplied in the bucket 20 and the cut ingot from an upper opening 3a of a melting furnace 3. Thus, the return material and the ingot are inserted into the melting furnace 3 in a mixed condition. Therefore, the proportion of the return material and the ingot in the furnace is constant, so that a constant casting product is always formed by the casting machine 2.
