The RCIcast casting machine, also referred to as the Drawing Unit, is positioned integrated on the top surface of the furnace. The unit consists of a desired number of copper crystallizer cooling pipes (CCP), depending on the capacity. Each CCP has a cylindrical graphite liner on its inner surface, and the transitions in the system are facilitated through pressure-resistant cooling pipes.
At the part of the cooling pipes that comes into contact with molten copper, there is a ceramic protective shell (cylindrical graphite protective sleeve) approximately 250 mm in length. For the controlled solidification of molten copper, reverse osmosis (RO) water is passed through each crystallizer copper pipe to ensure effective cooling.
The drawing unit is controlled by the Siemens Servo Group, and speed management can easily be carried out by the operator through the HMI panel. The immersion depth of the crystallizer in the molten copper is automatically adjusted based on data from the level control system. This adjustment is performed by the operator with the push of a single button, offering a user-friendly interface.
There are two absolute encoders in the system:
One is used to provide feedback from the float valve;
And the other is used to control the casting machine level.
RCIcast® casting machines enable standard rod production in diameters ranging from 8 mm to 25 mm. In addition, custom manufacturing is available for rods in different sizes based on customer requirements.
