Customized Centrifugal Casting Steel Spool Of Non-ferrous Metal Sheet
Product Application
The customized steel spool is designed for non-ferrous metal sheet, strip, and foil rolling equipment. It can be used as a roll support sleeve or other rotating support component in copper, aluminum, and titanium rolling mills. The spool provides accurate support for rotating components and helps maintain stable operation during continuous rolling.
For precision rolling applications, concentricity and dynamic balance are important because dimensional deviation or rotational imbalance can affect equipment stability and product quality. GW Precision therefore applies controlled manufacturing and inspection processes to the steel spool.
The supplied product specification is 665 × 605 × 1900 mm, with 35CrMoV specified as the material. Other dimensions and material grades can be manufactured according to customer drawings and technical requirements.
Operating Conditions
Steel spools used in non-ferrous metal rolling mills may operate under different combinations of temperature, speed, load, and environmental conditions. In copper rolling applications, the rolling temperature can reach approximately 600°C, while aluminum foil rolling can involve relatively high rotational speeds with comparatively low rolling force.
The spool may also be exposed to cooling water, rolling media, metal debris, and oxidized material during operation. These conditions require suitable material properties and controlled surface quality.
Precision fit is another important consideration. The supplied technical information specifies a clearance of ≤0.02 mm for the relevant rolling-mill fit. The actual dimensional and fit requirements should be determined according to the equipment design and customer drawings.
35CrMoV Centrifugal Cast Steel
The customized steel spool uses 35CrMoV centrifugal cast steel. The supplied typical composition requirements include:
C: 0.30–0.38%
Cr: 0.80–1.10%
Mo: 0.20–0.30%
V: 0.10–0.20%
S and P: ≤0.015%
The material is selected for applications requiring strength, wear resistance, and fatigue performance. According to the supplied technical data, the centrifugal casting process can provide a casting density with porosity of ≤0.5%, compared with approximately ≤2% for ordinary casting.
The supplied performance data also indicates a tensile strength of ≥450 MPa at 600°C. Fatigue life is stated as approximately 30%–50% longer than sand casting under the specified comparison conditions.
Centrifugal Casting and Precision Manufacturing
GW Precision produces the steel spool blank through centrifugal casting. This process is used to manufacture cylindrical spool components and provides a controlled production route for the required material structure and casting quality.
After casting, the blank undergoes subsequent machining according to the product drawing. Precision machining focuses on the required dimensions, cylindrical surfaces, mating areas, and concentricity. These characteristics are particularly important for rotating components used in non-ferrous metal rolling mills.
The manufacturing process is arranged according to the spool structure and application requirements. Different dimensions, materials, and machining specifications can be accommodated for customized products.

Dynamic Balance Testing and Inspection
Dynamic balance is a key inspection item for rotating steel spools. To help control rotational stability, GW Precision can perform dynamic balance testing on the finished spool.
The company uses a dedicated ring-belt dynamic balancing machine and can perform 100% dynamic balance testing according to product requirements. Dynamic balance inspection is combined with conventional dimensional inspection and mechanical-property testing after heat treatment.
This inspection process provides a basis for evaluating the finished spool's dimensional accuracy, material condition, and rotational balance before delivery. For high-speed foil and strip rolling equipment, controlling these characteristics helps support stable operation of the rotating system.
Customized Manufacturing and Quality Management
GW Precision has its own professional processing, design, development, and manufacturing capabilities, supported by established machining techniques and experienced technical personnel. The company applies a structured management system and 6S management practices to support production organization and employee skill development.
Customized steel spools can be manufactured according to customer requirements, including different materials, dimensions, structures, and inspection specifications. The company's annual production capacity for non-ferrous metal sheet steel spools is approximately 4,000 sets.
GW Precision also provides after-sales service and maintains packaging capabilities for export orders. Finished steel spools can be packed in wooden boxes for transportation. The typical sea-delivery period is approximately 1.5–2 months, depending on order quantity and shipping arrangements. The nearest major export port referenced in the supplied information is Shanghai Port.
