Poor storage often causes rust, structural deformation, or surface scratches—undermining roll performance. Below are condensed rules for safe storage:

I. Storage Environment Requirements

1. Temperature & Humidity: Maintain 5–25°C and relative humidity ≤60%; deploy dehumidifiers during humid seasons.

2. Cleanliness: Keep the area free of dust, oil, and corrosive substances (e.g., acids); clean floors regularly to avoid contaminant buildup.

3. Light & Ventilation: Install sunshades to block direct sunlight (prevents oil film degradation) and ensure gentle ventilation (avoid strong winds that disrupt oil films).

II. Proper Placement Standards

1. Specialized Brackets: Use V-shaped brackets made of wood or rubber (load capacity ≥1.5x the roll’s weight). Support rolls at the neck (100–200mm from the roll body end)—never on the working surface.

2. Stacking Rules: Only stack small rolls (diameter ≤300mm, length ≤1.5m)—limit to 3 layers and place rubber pads between rolls. Store large rolls (diameter >500mm) individually.

3. Isolation & Handling: Keep a 10–15cm gap between rolls and separate them from other spare parts. Use soft slings (never steel cables) when moving rolls to avoid scratches.

III. Regular Storage Inspections

- Idle ≤1 month: Weekly checks (verify anti-rust film integrity, rust signs, and bracket stability).

- Idle 1–3 months: Inspect every 3 days—add radial runout tests (tolerance ≤0.02mm).

- Idle >3 months: Daily temperature/humidity checks; rotate rolls 180° every 2 days to prevent deformation.

IV. Common Storage Mistakes to Avoid

Misconception	Correct Practice
Placing rolls directly on the floor	Use V-shaped brackets to support roll necks
Storing rolls in damp, unventilated spaces	Dehumidify and ventilate to keep humidity ≤60%
Stacking large rolls	Store large rolls individually
Leaving rolls stationary during long idleness	Rotate rolls 180° monthly for idle periods over 1 month
