Product Description
OEM 9Cr2Mo 42CrMo Heavy Industrial Forged Steel Cold Rolling Mill Work Roll mill roller Steel Plant support shaft
| 1, Raw material: | use ESR ingot. ESR need to melt twice, secondary refining process.Non metallic inclusions in steel are absorbed by slag. |
| 2, Heat | Natural gas heating furnaces are monitored and controlled by computer programs to ensure precise heating within set time and temperature range as required. |
| 3, Forging | Calculate the appropriate forging ratio based on the shape to avoid material waste. Select appropriate equipment for forging. Make the product undergo complete forging and pressing. |
| 4, Normalized: | can improve the toughness of steel |
| 5, Aligning | For shaft, roller, round bar |
| 6, Pre-machining | Remove surface oxide scale and inspect for defects. More conducive to complete immersion during tempering. |
| 7, Make UT | Qualified technicians shall conduct ultrasonic testing operations. Ensure that the product is 100% inspected and qualified. Magnetic particle testing and penetration testing can also be performed. |
| 8, Heat treatment: | Quenching&Tempering, to meet mechanical performance requirements.We will manufacture samples and continuously adjust the furnace temperature to meet the required performance requirements. Ensure 100% success data is obtained before mass production. |
| 9,Mechanical performance inspection and twice UP inspection | Hardness,Tensile strength,Yield Strength,Percentage elongation,Impact |
| 10,Precision machining, to achieve dimenssion on drawings. | We will pay attention to the tolerance requirements for each dimension. Surface smoothness requirements. The depth and type of drilling. Geometric tolerances, parallelism, perpendicularity, runout tolerances, concentricity, etc. |
| 11,Packing and delivery. | We will choose packaging methods that can protect the product and are suitable for sea transportation. With a complete supply chain, products can be transported to your factory by sea or rail. |
| Design: | We use the most advanced mould design software Auto CAD, Pro/E, Solidworks, UG (dwg, dxf, IGS, STP, X-T) |
| Manufacture: | We use advanced technology, unmatched skill, professional and advanced equipment size range from 10kg -10T, and experienced technicians to fit our customers requirements, like tooling manufacturing,forging CNC machining, Assembling and surface treatment service |
| Process and Capability: | Cnc machining, Threading, Welding, Tapping, Riveting, Grinding, Laser cutting,Metal Fabrication,forming,spinning, CNC Punching, Plasma cutting, Goffered, Stretch forming ,Tig/Mig Welding,Assembling, Shearing, Blanking, CNC Bending............ |
| Price Terms: | Fob Ningbo or Shanghai or any other port in CHINA. EXW, CIF, DDP, DDU. We have a mature supply chain and can provide door-to-door services. |
| Lead time: | 20-50days based on the different products |
| Packaging: | Wooden package and canton case or as per customers' requirement |
