What is the copper rod upper lead? The following is a brief introduction.
First, advanced structure
(1) The melting furnace is designed to grow into a square shape, so that the whole electrolytic copper can be fed without increasing the heat dissipation area of the furnace.
(2) With separation furnace replaced, furnace, melting furnace and the holding furnace add a transition between warehouse, copper liquid from the melting furnace by the transition to avoid directly into warehouse into the holding furnace, it is not only beneficial to stable temperature and liquid level and get more fully in transition cavities make molten copper reduction, at the same time can be relatively easy to remove slag quality within the transition warehouse, uniform stability of copper liquid temperature, liquid level stable, The copper liquid is clean, so that the quality of the copper rod is stable.
(3) The W-shaped groove is used to make the copper liquid flow in the groove with directional high speed, and there is sufficient heat exchange, so that various high melting point oxidation slag and eroded quartz sand flow out of the groove with the liquid flow. Accelerate THE FLOW OF COPPER LIQUID in MOLTEN COPPER, which can not only shorten the melting time, improve the production capacity of electric furnace, but also reduce the temperature in the molten groove, avoid slag blockage, so as to improve the working life of furnace. In terms of energy consumption, the original power consumption per ton of fused copper has been reduced from more than 400KWh to less than 350KWh, and the energy saving has been reduced by more than 20%.
(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 are also different. The design of detachable inductor can be in the failure of a certain inductor, so that in the failure of a certain inductor, it is not necessary to remove the whole furnace, but only to remove the damaged inductor, so as to save furnace shutdown time and production input.
Two, continuous casting traction machine is the key equipment of up drawing method
(1) Up-lead continuous casting is realized by intermittent upward traction. The pitch of the lift of each action of intermittent traction, the start-stop ratio of intermittent traction, the traction frequency and pitch will affect the quality of the casting rod. Using SERVO MOTOR traction system, not only meet the high frequency of intermittent traction, pitch can be adjusted according to different diameter of casting rod, and will not slip, stable operation.
(2) crystallizer is an important part of a tractor, speed up for the quality of the casting bar and decisive role, especially in a cooling zone structure, material selection and processing precision, but directly affect the heat transfer effect and the crystallization rate, the secondary cooling zone, brass mould the clearance between the lining and casting rod to casting rod cooling effect has great influence.
(3) One of the characteristics of the electronic control system is the simple process of up-lead continuous casting, but the requirements for process operation are very strict. The temperature of liquid copper, the level of liquid copper, the temperature at which the mold is inserted into liquid copper, the pitch and frequency of traction, and the pressure, flow and temperature of cooling water must be controlled within a certain range. The NEW TYPE OF UPCASTING TRACTION UNIT HAS a COMPLETE set OF CONTROL and alarm SYSTEMS, such as automatic control of LIQUID copper temperature, alarm of extreme high temperature and extreme low temperature, automatic tracking of liquid level, etc.
Three, eliminate the core process technology of copper rod hollow control oxygen content:
After nearly 20 years of continuous improvement and exploration, a set of unique technology has been developed. Advanced core technology that can effectively eliminate the empty core and control the oxygen content in the range of 10ppm.
