Rotary Slitting Principles and Applications Part 3
Apr 26 2016 · THE MACHINES Although design details vary slitting installations fall into either of two very distinct design styles. A good many lines for light gauge small coils of narrow width (Fig. 17) have the slitter and recoiler assembled on a common base. Some even have the uncoiler and scrap winder on that same base. (Fig. 18) These

Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing they recrystallize which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal like semi-finished casting products such as slabs blooms and billets.
