Customized 35CrNiMo Steel Reel Of Copper Plate

Application in Copper Strip Production

Copper strip manufacturers use uncoilers to continuously feed coils into the production line. The uncoiler supports and rotates the coil, allowing the strip to be released continuously and supplied to the following production processes. GW Precision steel sleeves are used as important supporting components in this equipment.

The customized 35CrNiMo steel sleeve can be used for roll-neck or reel-related support applications. It helps protect the contact area from wear and deformation caused by repeated rolling loads and supports stable coil uncoiling during continuous operation.

For the supplied product, the sleeve specification is Φ570 × Φ500 × 1830 mm. The actual dimensions can be customized according to the uncoiler structure, coil dimensions, equipment configuration, and customer drawings.

Working Conditions

The steel sleeve used in copper strip production may operate under repeated and alternating loads. During continuous rolling and coil handling, the component can experience repeated forces and minor impact loads, including the loading conditions generated when the strip enters the rolling process.

The supplied operating temperature range is approximately 80–150°C, resulting from rolling friction and heat transferred from the copper strip. The sleeve may also come into contact with emulsion or rolling oil, so material selection and surface condition need to be considered for the actual operating environment.

Dimensional stability is particularly important when the sleeve is installed on a roll neck or related rotating component. The supplied reference specifies an interference fit with an interference amount of approximately 0.05–0.10 mm. The final fit should be determined according to the actual equipment design and customer technical requirements.

35CrNiMo Steel Material

The customized sleeve is manufactured from 35CrNiMo steel, a high-strength alloy steel suitable for components subjected to repeated loading and demanding mechanical conditions.

The supplied typical chemical composition is:

• C: 0.32–0.40%

• Cr: 0.60–0.90%

• Ni: 1.25–1.65%

• Mo: 0.15–0.25%

The material is selected for its combination of strength, toughness, hardenability, and fatigue resistance.

According to the supplied material data, the tensile strength can reach ≥980 MPa, while impact energy can reach ≥50 J under the specified material and treatment conditions.

The hardenability of 35CrNiMo also makes it suitable for heat treatment of relatively large-section components. This is useful for customized steel sleeves where mechanical properties need to be controlled throughout the component section.

Heat Treatment and Quality Control

Heat treatment is an important part of manufacturing the 35CrNiMo steel sleeve. For large-section components, heat treatment needs to be controlled carefully to achieve a more uniform material condition. The supplied process requirements include segmented heating or rotary quenching where applicable.

Residual stress is another consideration during production. Vibration aging treatment can be introduced before precision machining when required to help reduce residual stress and improve machining stability.

Material purity is also controlled during manufacturing. The supplied requirements specify control of phosphorus and sulfur content to ≤0.015% to reduce the risk of temper brittleness.

The final manufacturing and inspection requirements are determined according to the customer's drawings, material specifications, equipment configuration, and application conditions.

Precision Manufacturing and Customized Processing

GW Precision manufactures customized steel sleeves according to customer requirements rather than limiting production to a fixed standard size. The machining process is arranged according to the sleeve dimensions, internal and external diameters, mating surfaces, fit requirements, and overall equipment structure.

For the copper strip uncoiler application, accurate dimensional control is important because the sleeve works together with the reel, roll neck, or other rotating components. Proper machining helps maintain the required fit and supports stable rotation during continuous operation.

The combination of material selection, heat treatment, residual-stress control, precision machining, and inspection provides a controlled manufacturing process for customized 35CrNiMo steel sleeves.

Uncoiler and Production Line Application

The uncoiler is an important component of a continuous strip production line. Its primary function is to unroll the coil and provide a continuous strip to the downstream equipment. Stable uncoiling helps maintain production continuity and supports efficient operation of the entire line.

The customized 35CrNiMo steel sleeve is one of the supporting components used in the uncoiler system. It helps protect the reel and coil contact area during uncoiling and supports stable coil handling. Depending on the equipment design, the sleeve can also help accommodate different coil inner diameters, making coil changes more convenient and reducing changeover time.

For copper strip manufacturers, the sleeve therefore forms part of the mechanical system that supports continuous coil processing. Its material strength, dimensional stability, fit accuracy, and manufacturing quality all contribute to reliable equipment operation.

Customized Steel Sleeve Manufacturing

GW Precision provides customized steel sleeve manufacturing for copper strip, aluminum strip, sheet, foil, and other rolling applications. Products can be manufactured according to customer drawings, specified materials, dimensions, application conditions, and technical requirements.

The supplied annual production capacity and established production management system support customized sleeve manufacturing for different industrial applications. GW Precision also maintains an after-sales service system and has established packaging capabilities for the safe handling and transportation of finished products.

For customers requiring a customized sleeve for a copper strip uncoiler or rolling mill, GW Precision can coordinate material selection, machining, heat treatment, inspection, and packaging according to the specific project requirements.
