Description

Technical Field

[0001] This utility model relates to the field of rolling mill neck technology, and in particular to a rolling mill neck grinding device. Background Technology

[0002] Rolls are the main working components and tools on a rolling mill that cause continuous plastic deformation of metal. The roll neck is a crucial part of the roll, located at both ends.
