Hot Rolling
Hot rolling happens after casting but before this.
What is cold rolling?
Cold rolling affects appearance and the quality of this part of the aluminum sheet.
What is the surface?
This is often applied at finishing and could be a paint or lacquer.
What is coating?
This is a piece of aluminum that has been cast and is ready for rolling.
What is an ingot?
CES stands for this term referring to part of an aluminum beverage can.
What is can end stock?
During hot rolling, you may see this type of mill that rolls the ingot back and forth to reduce its thickness.
What is a reversing mill?
Two types of annealing are batch and this.
What is continuous?
Lubrication is used to protect this from deformation or damage.
What is the surface?
Daily Double:This is a process critical for removing hydrogen from aluminum.
What is degassing?
This is the visible pattern showing the way that the aluminum sheet was conveyed through the mill.
What is rolling direction?
Strain from rolling is highest here and lowest at the center.
What are the surfaces?
Cold rolling is performed below the recrystallization temperature so only this will occur.
What is recovery?
Finishing happens after this type of rolling.
What is cold rolling?
Inclusions that are left in the aluminum can cause cracks and these which are common in can body stock.
What are tear offs?
This is the part of the can that gets thinner at the top.
What is the neck?
Daily Double:Hot rolling strain, strain rate, temperature, and inter pass conditions all cause variations in the final this.
What is microstructure?
Although called cold rolling the average temperature of aluminum exiting the cold mill is 90-this degrees Celsius.
What is 200?
Finishing looks at different surface qualities including color, brightness, and this-which is also something you put on your lips.
What is gloss?
This is used to remove inclusions from the molten aluminum.
What is a bed filter?
Novelis recycles this many aluminum cans every year.
What is >82 billion?
Due to edge-center-edge variation of grain size and texture, this cup's profile is also variable from edge-center-edge.
What is earing?
Annealing is a process that can be used to improve these properties of aluminum, such as strength and hardness.
What are mechanical properties?
This is an electrochemical process that thickens that natural oxide layer of the aluminum and improves the finish.
What is anodizing?
The most common type of aluminum casting that uses water curtains to cool molten Al in a mold.
What is direct chill casting?
It's not just aluminum, it's this.
What is Novelis Aluminum?
