The invention discloses a bonding wire continuous casting furnace. The bonding wire continuous casting furnace can carry out continuous casting under the high-vacuum state, a casted bonding wire is intermittently wound on a receiving frame, a metal melt portion is provided with a stirring device driven by a motor, the stirring device is an eccentric stirring device, when the eccentric stirring device rotates, liquid-state metal raw materials are continuously stirred, a cooling copper mold and a water cooling circular pipeline are adopted in a cooling part, liquid-state metal can be effectively solidified, and the cooling efficiency is high; the vacuum part is provided with an observation window, and a guide device with the cooling effect, the vacuum part draws air, vacuum is formed, in a cavity without air, the bonding wire cannot be oxidized, the bonding wire is cooled from the guide device, after cooling, the bonding wire enters the guide part, and the bonding wire is guided into the receiving frame through the guide part. The bonding wire continuous casting furnace can carry out continuous casting under the high-vacuum state, the produced bonding wire is good in quality, and the production efficiency is high.
