Manufacturing Record
A quenched-and-tempered 30Cr2Ni2Mo roll-neck forging engineered for load transfer, wear resistance and dimensional stability.
Engineering case
Component application, material and performance requirements are translated into defined manufacturing controls and documented verification.
Hot and cold rolling lines
30Cr2Ni2Mo alloy steel
For Hot and cold rolling lines, the Metallurgical Roll Neck must use 30Cr2Ni2Mo alloy steel at project-specific dimensions and weight while meeting Tensile strength >= 980 MPa; Yield strength >= 835 MPa; Elongation >= 13%; 240-280 HBW. The engineering challenge is coordinated control of metal flow, section uniformity and internal integrity.
The forming strategy controls metal flow, section uniformity and internal integrity. Heating practice, deformation sequence, forging reduction, heat treatment and machining allowance are coordinated with defined material, dimensional, NDT and property release points.
Delivery basis: Machined condition. Tensile strength >= 980 MPa; Yield strength >= 835 MPa; Elongation >= 13%; 240-280 HBW are incorporated into the project inspection plan, with final inspection records and the quality dossier supporting acceptance and release.
