PURPOSE:To obtain an excellent casting in the stage of pouring molten copper from a holding furnace into a casting mold by reading the temp. rising speed of spouts provided before and behind the holding furnace and controlling the temp. of the molten copper to be supplied into the casting mold. CONSTITUTION:A temp. detector is attached to a spout 2 which conducts the copper melted in a shaft furnace 1 to a holding furnace 3 and/or a spout 4 which conducts the molten copper from the furnace 3 to a tundish 5, etc. The temp. rise DELTAt deg.C at the time DELTAH is then measured. A copper wire calculated preliminarily to meet the measured DELTAt/DELTAH is supplied to a molten metal well 6 in accordance with the change in the speed of a pinch roll 9 driven by a motor 8, thereby controlling the temp. of the molten copper to be supplied into the casting mold. |
