Manufacturing Record
A quenched-and-tempered 42CrMoA roll core designed for tension, bending and continuous paper-machine service.
Engineering case
Component application, material and performance requirements are translated into defined manufacturing controls and documented verification.
Paper-making lines
42CrMoA alloy steel
For Paper-making lines, the Paper-Mill Roll Core must use 42CrMoA alloy steel at project-specific dimensions and weight while meeting Tensile strength >= 1080 MPa; Quenched and tempered. 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 >= 1080 MPa; Quenched and tempered are incorporated into the project inspection plan, with final inspection records and the quality dossier supporting acceptance and release.
Heat/lot traceability and chemical analysis
Mechanical-property testing to the approved specification
UT / MT / PT and dimensional inspection as technically required
Material certificate and heat/lot traceability
Heat-treatment and inspection records
Final dimensional report and release dossier
