Inspected By Dynamice Balancing Test Dedicated Stainless Steel Sleeve Of Aluminum Foil Mill Machine
The special 304 stainless steel sleeve for aluminum foil rolling mill is a key component in the precision rolling process, mainly used to support the rolling mill, transmit torque, and ensure the uniformity of aluminum foil thickness.
GW precision Sleeve Product information
| Sleeve Material | Specification |
| 304 stainless steel | 355*305*1300 |
Chemical composition of 304 stainless steel (mass percentage)
According to ASTM A240/A240M standard, the typical composition is as follows:
Range of Element Content (%) Function
Chromium (Cr) 18.0-20.0 corrosion resistance, oxidation resistance core element
Nickel (Ni) 8.0-10.5 stabilizes austenite structure and enhances toughness
Carbon (C) ≤ 0.08 controls intergranular corrosion risk
Manganese (Mn) ≤ 2.0 for deoxidation and improved processability
Silicon (Si) ≤ 1.0 enhances high temperature strength
Phosphorus (P) ≤ 0.045 impurities, strict control is required
Impurities with sulfur (S) ≤ 0.030 affect thermal workability
Nitrogen (N) ≤ 0.10 solid solution strengthening (trace)
Special Process Requirements for Stainless Steel Sleeves for Aluminum Foil Rolling Mill Tested by Dynamic Balance Test
Dynamic balance control:
High speed sleeves need to undergo multi speed testing (such as 500/1000/1500 rpm segmented calibration);
The dynamic balance level usually requires G1.0~G2.5 (ISO 1940 standard).
Anti micro motion wear:
The contact surface with the rolling mill can be treated with laser micro texturing to reduce adhesive wear.
The core of the 304 stainless steel sleeve for aluminum foil rolling mill lies in high-precision machining and dynamic balance control. By using solid solution treatment to ensure material properties, combined with precision grinding and dynamic balance correction, the stringent requirements for surface quality and operational stability in aluminum foil rolling can be met. The production cycle is usually 4-6 weeks (including heat treatment and testing), and the lifespan is about 3-5 years (depending on maintenance).
GW Precision adopts advanced smelting and casting technology, with the equipment has accurate inspection to ensure the chemical composition of the Stainless Steel Sleeve material is reliable and accurate. Centrifugal casting is adopted to guarantee the inner and outer surface of the sleeve is free from defects such as cracks, slag inclusion, pores and sand holes.
Description of heat treatment of steel sleeve:
GW Precision always conduct strictly for steel sleeve heat treatment which have the specifically demand in mechanical property and make sure every product to achieve the best condition and customers’ good results.
