Introduction

Technological Evolution of the New Edition of Metallurgical Roller Terminology Standards

Classification Dimensions	1995 Edition	2022 Edition	Technological Breakthroughs
Basic Terms	23 Items	37 Items	11 New Groups of Roller Ring/Stress Detection Terms
Manufacturing Process	6 Types of Methods	14 Types of Methods	Addition of Laser Cladding and Electroslag Composite Process
Rolling Configuration	9 types of rolls	21 types of rolls	Newly added ultra-wide cold-bent steel rolls, combined rolls, etc.

The new version of the standard strengthens the roll performance index system:

Roller hardening layer depth definition revised to the radial matrix control range of cast iron roll with carbon content＞2.1%
New hardness drop(≤5HS/10mm) as the core detection index of roll life
Introduced the wear-resistant coating bonding strength detection method of laser cladding roll

Centrifugal casting composite roll actual application indicators:

Process parameters	Traditional process	Comparison with new technology
Working layer thickness	≤40mm	80-120mm
Carbide distribution	10-15%	30-35%

Equipment selection for projects under construction should give priority to the new version of combined roll technical parameters
Reconstruct the roller inspection system to meet the 10Mhz accuracy requirements of the newly added wave/eddy current inspection
Optimize the normalizing temperature control curve of 40MnB alloy in the roll heat treatment process in accordance with the new version
