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

1. Advanced structure

(1) The melting furnace is designed to be rectangular, so that the whole electrolytic copper can be fed without increasing the heat dissipation area of the furnace.

(2) The split furnace is replaced by a conjoined furnace, and a transition warehouse is added between the melting furnace and the holding furnace. When the copper liquid flows from the melting furnace through the transition warehouse into the holding furnace, the direct inflow is avoided, which is not only conducive to the temperature and liquid level. In addition, the copper liquid can be more fully reduced in the transition chamber, and the slag can be easily removed 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 is improved. stability.

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

(4) In general, the life of the furnace body is 2-5 times that of the inductor, and the life of the inductor of the melting furnace and the holding furnace is also different. It is designed as a detachable sensor so that when a certain sensor fails, it is not necessary to dismantle the whole furnace, but only need to remove the damaged sensor body to rebuild, thus saving the shutdown of the furnace. time and production input.

2. The continuous casting tractor is the key equipment of the upward-drawing method

(1) The upward lead continuous casting is realized by intermittent upward traction. The pitch of the lift of each action of the intermittent traction, the start-stop ratio of the intermittent traction, the traction frequency and the pitch will affect the quality of the casting rod. The servo motor traction system is adopted, which not only satisfies the intermittent traction of high frequency, but also the pitch can be adjusted arbitrarily according to the diameter of different casting rods, and it will not slip and run stably.

(2) The mold is an important part of the traction machine, which plays a decisive role in the quality and speed of the casting rod, especially the structure of the primary cooling zone, the selection of materials and the machining accuracy, but it directly affects the effect of heat conduction and crystallization Speed, the size of 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) The simple process of the upward-drawing continuous casting of the electronic control system is one of its characteristics, but the requirements for the process operation are very strict. The pitch, frequency of traction and the pressure, flow and temperature of cooling water must be controlled within a certain range. The new type of upward continuous casting traction unit has a relatively complete control and alarm system, such as automatic control of the temperature of molten copper. And the alarm of extreme high temperature and extreme low temperature, automatic liquid level tracking, etc.

3. The core process technology to eliminate the hollow copper rod to control the oxygen content:

After nearly 20 years of continuous improvement and exploration, a unique process technology has been developed. Advanced core technology that effectively eliminates hollow cores and controls oxygen content within 10ppm.

(4) Under normal circumstances, the life of the furnace body is 2-5 times that of the inductor, and the life of the inductor of the melting furnace and the holding furnace is also different. It is designed as a detachable sensor so that when a certain sensor fails, it is not necessary to dismantle the whole furnace, but only need to remove the damaged sensor body to rebuild, thus saving the shutdown of the furnace. time and production input.
