An oxygen-free copper rod production line comprises a melting furnace, an up-draw mechanism, a take-up mechanism and a production speed control system. The production speed control system comprises a computer, a temperature sensor, a pressure sensor, an up-draw motor, a take-up motor and infrared sensors, wherein the temperature sensor, the pressure sensor, the up-draw motor, the take-up motor and the infrared sensors are connected with the computer. During production, when the quantity of molten copper in the melting furnace is changed, the pressure sensor above a draw area timely transmits pressure data to the computer, and the computer timely adjusts the speed of drawing up a copper rod, so that the solidification pressure of molten copper in a crystallizer is kept constant. When the temperature in the up-draw area is different, the temperature sensor transmits data to the computer, and the computer controls the crystallization quality of the copper rod by adjusting up-draw speed and controlling the temperature of a constant-temperature heating device. When the speed of drawing up the copper rod is changed, the copper rod at the front end of the take-up mechanism can sink or rise. When the copper rod touches the infrared sensors at two ends of a sensor support, the infrared sensors can inform the computer of controlling take-up speed.
