Oxygen-free copper rod production line

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of copper rod production equipment by upward continuous casting method, and relates to an automatic production line of oxygen-free copper rods. Background technique [0002] Oxygen copper rod is the main raw material for the production of enamelled copper wire. The main method of producing oxygen-free copper rod is the up-drawing continuous casting method. At present, the production line of the up-drawing continuous casting method is mainly composed of a melting furnace, The electronic control system is composed of the electronic control mechanism. The electric control mechanism mainly controls the speed of the copper rod's up-drawing speed and the speed of the wire. Since the amount of copper liquid in the melting furnace will change with the production of copper rods during the production process, when the liquid level of the copper liquid in the melting furnace rises and falls, the upward pressure of the ...
