This unit includes the following parts:
1. Loading Zone
2. Melting Zone
3. Zone solidification
4. Cooling Zone
5. Unloading zone
6. Power Converter
Loading Zone
scroll -Piano in tapes for the automatic loading of the ingot in the pushing ramp.
Motorized -Spintore for precise positioning of the brackets
Melting Zone
-room fusion with adjustment of the operating temperature: ~ 1200 ° C.
-System induction heating.
-Area melting enclosed by panels of insulating materials with an inert gas inlet at the entrance of the brackets.
-Avanzamento of the brackets on tubular guides cooled steel AISI310
-Monitoring and temperature adjustment by means of pyrometers (working range 600-1800 ° C) with on the operator panel display.
Solidification Zone
Area which allows the withdrawal of the cast ingot management; self-regulating system in relation to the following parameters:
• ambient temperature
• cooling water flow
• cooling water temperature
The system allows to ensure the highest quality of the surfaces of the finished ingot.
Cooling Zone
cooling -Double protected and closed.
Room -Length studied to better control the cooling curve (the brackets with the ingots must exit at a temperature of ~ 30-40 ° C)
Unloading zone
-tape of ejection of the ingot from the cooling chamber
-Piano scroll for the storage of melted ingots.
