Energokomplekt installed Conform extrusion line
The equipment is intended for continuous extrusion of shaped (sector) aluminium cores with the section of 25÷240 mm2 and round aluminium cores with the section of 25÷1,000 mm2. The machine capacity is up to 400 kg/h (depending on the product).
The industrial computer system with a highly specialised software installed at the line enables measuring and recording operational parameters (temperature, speed, drive load, etc.), visualising graphically any four primary parameters for recent 24 hours every second, controlling the dynamic systems (line speed, input shaft rotation frequency, receiving device operating parameters, operating space temperature, etc.), calibrating inputs and outputs of the system and other.
Key advantages of the process at the new line include:
Conform technology allows achieving a homogeneous structure of the product through the intensive plastic strain method. Due to internal friction, the metal is heated to plastic strain temperatures, pushed into the chamber and extruded through the spinning nozzle to produce a product of any shape. As the material generates friction heat and transformation heat, a temperature of up to 500 C° can be reached without a heater. The extruded material is fully recrystallised and has a high plasticity creating an electric conductor.
For reference. Conform technology was developed by the United Kingdom Atomic Authority (UKAEA) as a continuous metal extrusion method in 1971. The technology found its application in the production of long-length aluminium and copper products, steel wire coatings, and multi-bore tubes. However, for metals which are heavier and harder than copper and aluminium, such problems like insufficient strength of the tools and low quality of the product limited that application area of the internal friction heating technology.
