Features Of Up Casting Units
Up casting units could directly produce lengthy oxygen free copper rod, slab
ingots and tube billets from electrolytic cathode copper and bright copper, which features advanced process, high product quality, low investment, various specifications and no pollution of three wastes. The Up-casting units are ideal choice for manufacturing copper conductor and copper materials. The copper products could be further treated for a variety of bare copper wires, flat copper wires and special wires as well as red copper buses and tubes for the mechanical and electrical sectors.
Characteristics of Units and Process
Logical structure of Units
Targeting the requirements of processing the sole metal material (pure copper), the melting furnace and maintaining furnace adopt the mains frequency core induction furnace, which increases the power factor of the melting furnace and decreases the investment.
The combined furnace technology is adopted for the unit melting furnace and
maintaining furnace. The copper liquid is connected through channels under the liquid level, which could avoid oxidation, splashes, gas absorbing and reduction of heat losses at the time of copper liquid transfer.
Provided the unit with three inducers is selected, no other 3-phase balance devices are required to be installed since the three inducers possess 3-phase balance function. In case of selection of units with one or two inducers, additional devices are required.
The traceable system of up-casting units could ensure the depth of immersed
crystallizer in the copper liquid is kept stable for a considerable time and as such the quality of the copper products could be guaranteed.
According to the different requirements for manufacturing various copper rods, tubes and bars, the mechanical drawing machine and servo drawing devices are available.
The wire winders could also be selected for continuous operation and intermittent operation, which ensure a optimal performance of the units.
Advanced Process
From the raw electrolytic copper anode (panel) to the semi-product- copper rod, tube and bar, the process could be completed at one time, sparing the conventional operations such as ingots, rolling and stretching.
The profile and dimensions of the casting billets depend on the design and fabrication of graphite mould passes, which is simpler than the conventional design and fabrication of rolling and stretching mould passes.
The twin-drawing technology of the units makes it possible for production of different profiles and cross-section products.
The electrical-mechanical integration is strengthened with the aid of servo motor driving, dual-frequency controlled wire winding and PID.
High Quality Products
Given the products are electrolytic cathode copper and bright copper, the
crystallization is completed under the copper liquid against graphite or charcoal.
Thereby the attained copper products are low oxygen contained and free from foreign matter, featuring high brightness and conductivity.
Since the operations for Up-casting are continuous and the service life of the
graphite is not less than 72 hours, the total weight for single copper rod could be 2-3T In the continuous operations, which is beneficial for requirements of lengthy products, contact line (No butt welding is allowed) as well as follow-up high-speed drawing treatment..
As for the small diameter upcasting copper rods (e.g. ø8mm), no hardening treatment is required. Therefore the later treatment is simpler and it consumes less energy.

Variety of Products
For the different production, only several spare parts are required to be replaced such
as crystallizer, plates, drawing wheels and wire winders.
The space and drawing speed could be regulated in a convenient manner.
Since the output voltage of the melting furnace is simple for regulation and the
quantity of the crystallizers could be determined as required, it is very convenient to
adjust the production output at rated settings.
The auxiliary cutting machine could also be provided for manufacturing special tubes
and bars.
Meeting different customers
The production capacity of the unit vary from 1000T to 5000T based on different
Specifications.
The degree of mechanization and automation could be configured according to the
customer’s preference. And the price varies a lot accordingly.
The raw materials for manufacturing could automatically be fed via mechanical
treatment or manually cutting
The follow-up equipments for the unit could be selected at option such as cold rolling
machine, super large stretcher, large stretcher and plate cutting roller.
No three-wastes
The operating noises are relatively low for the up-casting equipments.
No harmful gases escape and no waste liquid or waste solid are produced as the
conventional acid washing has been omitted.
