Step 3: after casting starts, first preheating fine aluminium stick/band by preheating mechanism, then starting clamping fortune
Send mechanism by fine aluminium stick/with insertion smelting furnace in melt in, and by speed adjusting gear control fine aluminium stick/band decrease speed,
After fine aluminium stick/band insertion melt, fine aluminium stick/band insertion portion will gradually be melted and be added in melt, molten to change
Aluminium content in body, and then the alloy content in melt is made also to change；
Step 4: the melt that aluminium content changes continuously is introduced into crystallizer, and is kept under dummy bar head
It moves, until casting terminates.
In step 2, melt forms the time used in green shell in crystallizer as 5~60s.
In step 2, after casting starts, the speed that initially moves down of dummy bar head is 5~50mm/min, and is increased in 2 minutes
Add to 10~150mm/min.
