Function Of Vertical Edger In Roughing Mill

Roughing Mill - an overview ScienceDirect Topics

Roughing mill rolling of reheated slab: The roughing mill usually consists of one or two roughing stands in which the slab is hot rolled back and forth 5 or 7 times repeatedly to reach the minimum thickness requirement. The roughing mill also contains edger rolls that are used to roll the edge of slab and center it.

Introduction to Milling Tools and Their Application

2021-1-20  Non-center cutting end mills have cutting edges only on the sides and are used only for side milling. These tools are identified by a small hole at the center. Roughing end mills have serrations in the teeth to quickly remove large amounts of material without creating vibration. The serrations produce many small chips and a rough finish.
