Rolling is a forming process which reduces the cross-sectional area of the incoming metal stock or produces a new cross-section of the material at the exit while improving its mechanical properties through the use of rotating rolls.
The process can be carried out hot, warm, or cold, depending on the application and the material involved. Rolling of blooms, slabs, billets, plates is usually done at temperatures above the recrystallization temperature (hot rolling). Sheet and strip often are rolled cold in order to maintain close thickness tolerances.
Specific Processes-
- Flat Rolling
- Thread Rolling
- Seamless Tubing
- Continuous Casting and Rolling
