Forged Rolls & Roll Blanks
Forged work rolls, backup rolls and roll blanks for hot and cold rolling mills — roll-specific grades, 100% UT tested.
Forged Rolls & Roll Blanks
Rolls work in the harshest steel-service environment there is: cyclic contact stress, thermal shock and wear, all in one part. Forged rolls and roll blanks are produced from roll-specific grades with strict internal soundness — every piece is 100% ultrasonic tested before shipment.
CREATEEL supplies forged roll blanks, work rolls, backup rolls and grinding-roll shafts from our two partner mills, covering the MC series and 9Cr / 60CrMnMo grade families. Delivered as-forged, rough machined or fully machined with heat treatment; hardness and UT records supplied per piece.

Manufacturing Process
Our forged steel products are produced through a 12-step forging process combining controlled heating, precision open/closed-die forging, tailored heat treatment, and CNC finish machining to achieve superior metallurgical structure and dimensional accuracy.
Raw Material Selection & Inspection
High-quality ingots or continuous-cast billets (EAF-LF-VD refined) are selected based on grade specification. Chemical analysis, surface inspection, and UT testing are performed.
Billet Sawing to Forging Blanks
Raw stock is cut to calculated forging weights using high-speed band saws, accounting for scale loss, flash, and machining allowances.
Furnace Heating
Blanks are heated to 1150–1250°C (depending on grade) in a gas-fired bogie-hearth or chamber furnace with precise zone temperature control to ensure uniform austenitization.
Open-Die / Closed-Die Forging
Heated blanks are forged using hydraulic presses or air hammers. Open-die forging uses flat/V-dies for simple bars; closed-die forging uses precision tooling for near-net-shape profiled components.
Trimming & Punching (Closed-Die)
For closed-die forgings, excess flash is trimmed in a mechanical press and holes are punched while the part is still hot, improving material utilization.
Post-Forging Heat Treatment
Forgings undergo normalizing, annealing, or quenching & tempering per material grade to refine grain structure, relieve residual stresses, and achieve specified hardness and mechanical properties.
Blasting & Surface Cleaning
Scale and oxide layer are removed by shot blasting (steel shot S230–S330) to reveal surface defects and prepare for machining.
Rough Machining
Excess forging allowance is removed by CNC lathe turning, leaving 2–3 mm finishing stock. Rough machining also removes surface decarburization and forging irregularities.
Ultrasonic Testing (UT)
100% ultrasonic inspection per EN 10228-3 or ASTM A388 detects internal defects such as cracks, inclusions, porosity, and segregation. Acceptance criteria as per grade requirements.
Finish Machining
CNC turning, milling, and drilling achieve final dimensional tolerances (up to IT7) and surface roughness (Ra 1.6–3.2 μm) per customer drawings.
Hardness & Metallographic Testing
Brinell/Rockwell hardness verification, tensile testing on sacrificial coupons, and metallographic examination for grain size, inclusion rating, and carbide structure (critical for tool/die steels).
Final Inspection & Packaging
Dimensional inspection of all critical features, MPI/LPT for surface defects if required, stamping grade and heat number, rust-proof oiling, and packing in wooden cases or steel bundles.
Applications
