What is the upcast copper rod machine? , The following is a brief introduction.

1. Advanced structure

(1) The melting furnace is designed to be rectangular, so that the whole piece of electrolytic copper can be fed without increasing the heat dissipation area of the furnace. What is the copper rod uplifting machine? , The following is a brief introduction.

(2) The split furnace is replaced with a conjoined furnace, and a transition bin is added between the melting furnace and the holding furnace. When the copper liquid flows from the melting furnace through the transition bin into the holding furnace, it is avoided to directly flow in, which is not only beneficial to the temperature and liquid level. It is stable, and the copper liquid is more fully reduced in the transition chamber. At the same time, it is easier to remove the slag in the transition chamber, so that the temperature of the copper liquid is stable and uniform, the liquid level is stable, and the copper liquid is clean, so that the quality of the copper rod stable.

(3) The W-shaped melting channel is used to form a directional high-speed flow of copper liquid in the melting channel, and there is sufficient heat exchange, so that various high melting point oxide slag and corroded quartz sand flow out of the melting channel with the liquid flow. Accelerate the flow of copper liquid in the molten copper, which can not only shorten the smelting time and increase the production capacity of the electric furnace, but also reduce the temperature in the melting channel, avoid the blockage of the slag, and increase the working life of the furnace. In terms of energy consumption, the original electricity consumption per ton of molten copper has been reduced from more than 400KWh to less than 350KWh, achieving energy saving and consumption reduction of more than 20%.

(4) Under normal circumstances, the life of the furnace body is 2-5 times the life of the inductor, and the life of the inductor of the melting furnace and holding furnace is different. Designed as a detachable sensor, it can be used when a certain sensor fails, so that when a certain inductor fails, the entire furnace does not need to be dismantled, but only the damaged induction rebuild is required to save the furnace shutdown. Time and production investment.

Second, the continuous casting tractor is the key equipment of the up-drawing method

(1) Upward continuous casting is realized by intermittent upward traction. The pitch of each movement of intermittent traction, the ratio of start and stop of intermittent traction, the traction frequency and pitch will affect the quality of the cast rod. The servo motor traction system not only satisfies the high-frequency intermittent traction, the pitch can be adjusted arbitrarily according to different casting rod diameters, and it will not slip and operate stably.

(2) The mold is an important part of the traction machine, which plays a decisive role in the quality of the casting rod and the pulling speed, especially the structure of the primary cooling zone, the selection of materials and the processing accuracy, but it directly affects the effect of heat conduction and crystallization The speed and the gap between the inner wall of the copper tube in the secondary cooling zone of the mold and the casting rod also have a great influence on the cooling effect of the casting rod.

(3) One of its characteristics is the simplicity of the process of up-drawing continuous casting of the electronic control system, but the requirements for process operation are very strict. The temperature of the copper liquid, the level of the liquid level, and the temperature of the mold inserting the copper liquid, The traction pitch, frequency, and the pressure, flow and temperature of the cooling water must be controlled within a certain range. The new upward continuous casting traction unit has a relatively complete control and alarm system, such as automatic control of the copper liquid temperature And extreme high temperature and extreme low temperature alarms, automatic liquid level tracking, etc.

3. Eliminate the core technology of copper rod hollow to control oxygen content:

After nearly two decades of continuous improvement and exploration, a unique process technology has been developed. Advanced core technology that can effectively eliminate the hollow core and control the oxygen content within 10 ppm.
