What is the Copper Rod Upward Continuous Casting Machine?

What is the copper rod upward continuous casting machine? The following is a brief introduction.

First, Advanced Structure

(1) The melting furnace is designed as a rectangular shape, which can be used to feed the whole copper without increasing the heat dissipation area of ​​the furnace.

 (2) Replace the split furnace with a one-piece furnace, and add a transition chamber between the melting furnace and the holding furnace. The copper liquid avoids direct inflow from the melting furnace through the transition chamber into the holding furnace, which is not only beneficial to 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 cleaned, so that the quality of the copper rod is improved. stable.

 (3) The W-type molten ditch is used to form a high-speed flow of copper liquid in the molten ditch, and sufficient heat exchange is performed to cause various high-melting-point oxidized slag and the damaged quartz sand to flow out of the molten ditch with the liquid flow. Accelerate the flow of copper in the molten copper, which not only shortens the melting time, improves the production capacity of the electric furnace, but also reduces the temperature in the molten ditch and avoids clogging of the molten slag, thereby improving the working life of the furnace. In terms of energy consumption, the original electricity consumption per ton of molten copper has been reduced from 400 KWh to less than 350 KWh, achieving energy savings of more than 20%.

 (4) In general, the life of the furnace is 2-5 times the life of the inductor, and the life of the inductor of the melting furnace and the holding furnace is also different. Designed as a detachable sensor, it can be used when a certain sensor fails, so that in the event of a failure of an induction body, it is not necessary to remove the entire furnace, and only the damaged induction weight building is removed, thereby saving the furnace. Time and production inputs.

Second, the continuous casting tractor is the key equipment of the upper method

(1) The upper continuous casting is realized by intermittent upward traction. The pitch of the lift of each intermittent movement, the opening and stopping ratio of intermittent traction, the traction frequency and the pitch all affect the quality of the casting rod. The servo motor traction system not only satisfies the high-frequency intermittent traction, but the pitch can be adjusted arbitrarily according to different casting rod diameters, and it does not slip and runs stably.

(2) The crystallizer is an important part of the tractor, which plays a decisive role in the quality of the casting rod and the speed of the upper lead, especially the structure, material selection and processing precision of the primary cooling zone, but directly affects the heat conduction effect and crystallization. The speed, the gap between the inner wall of the copper tube and the casting rod in the secondary cooling zone of the crystallizer also has a great influence on the cooling effect of the casting rod.

(3) The simple process of the continuous casting process on the electronic control system is one of its characteristics, but the requirements for the process operation are very strict, the temperature of the copper liquid, the level of the liquid level, and the temperature at which the crystallizer is inserted into the copper liquid. The pitch, frequency and pressure, flow rate and temperature of the cooling water must be controlled within a certain range. The new type of upper continuous casting traction unit has relatively complete control and alarm system, such as automatic control of copper temperature. And the alarm of extremely high temperature and extremely low temperature, automatic tracking of liquid level, etc.

Third, the core technology to eliminate the oxygen content of the copper rod hollow control:

(1) After nearly two decades of continuous improvement and exploration, a unique process technology has been developed. It can effectively eliminate air cores and advanced core technologies that control the oxygen content to within 10ppm.

 (2) Replace the split furnace with a one-piece furnace, and add a transition chamber between the melting furnace and the holding furnace. The copper liquid avoids direct inflow from the melting furnace through the transition chamber into the holding furnace, which is not only beneficial to 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 cleaned, so that the quality of the copper rod is improved. stable.

 (3) The W-type molten ditch is used to form a high-speed flow of copper liquid in the molten ditch, and sufficient heat exchange is performed to cause various high-melting-point oxidized slag and the damaged quartz sand to flow out of the molten ditch with the liquid flow. Accelerate the flow of copper in the molten copper, which not only shortens the melting time, improves the production capacity of the electric furnace, but also reduces the temperature in the molten ditch and avoids clogging of the molten slag, thereby improving the working life of the furnace. In terms of energy consumption, the original electricity consumption per ton of molten copper has been reduced from 400 KWh to less than 350 KWh, achieving energy savings of more than 20%.
