I.A.S. TEM-PRO-Heater® for isothermal extrusions
A temperature process fro the extrusion being as precise as possible is an important condition for a perfect manufacturing process.
Apart from the billet receiving temperature, particularly the temperature gradient of the billet to be pressed is a very important parameter of the process in order to guarantee the isothermal extrusion process.
Due to the mode of operation of gas-heated furnaces, front-lateral temperature gradients can be produced with so-called head-burners. However, in order to guarantee a high flexibility, the induction furnace is process-technically superior.
This is the reason for the demand of so-called reheating furnaces with several independantly adjustable heating zones which are integrated into the process line in order to impress the axial temperature distribution on the metal pin which is to be warmed up.
TEM-PRO-Heater®: Temperature distribution heat up system. Flexible heating concepts can be realized by using this high performance system combined with preheating gas furnaces or as stand-alone-solution. The productivity is increased by standardized interfaces at tools for isotherm extrusions.
The following requirements are realized with the I.A.S. TEM-PRO-Heater®
- production of an axially even basic temperature distribution
- short warming up times
- After reaching a pre-adjusted basic temperature, each zone can be opreated with independend power densities.
- processing of different block lengths
- processing of different alloys using the given heating-ups
- Prompting is simplified by the computer support, a faulty operation is almost impossible due to the use of a so-called prescription database; at the same time, all order-specific caracteristic values are available for documentation purposes. Furthermore, interfaces enable a simple binding to the control systems for the isotherm extrusions.
Further equipment characteristics distinguish this system
- modular structure: thus a problem-free integration into existing production lines with inductive pre-heaters is also possible
- The throughput can be increased by recording temperature of the pre-heaters simultaneously.
- fast changeableness of the warming up coil with changing diameters by code and quick-locking mechanisms
- use of electronic switchgears
- infinitely variable capacity control for each module with ITN (invertertechnology) system
- use of field bus systems (wiring-poor structure, high flexibility by using a sensor/actuator bus)
- high electrical efficiency
