Manufacturing Record
A 9Cr2Mo upper-roll shell developed for long-term wear resistance in paper-production lines.
Engineering case
Component application, material and performance requirements are translated into defined manufacturing controls and documented verification.
Paper-making machinery
9Cr2Mo alloy tool steel
For Paper-making machinery, the Paper-Mill Roll Shell must use 9Cr2Mo alloy tool steel at project-specific dimensions and weight while meeting High hardness; Wear-resistant roll surface. 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. High hardness; Wear-resistant roll surface 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
