Tấm thép không gỉ cán nguội ở dạng cuộn

Cold rolled stainless steel sheet in coil is produced by further processing hot rolled stainless steel through precision rolling at room temperature. The material is supplied in dạng cuộn dây, allowing continuous processing, cắt, and fabrication for industrial applications.

This product is widely used where tight tolerances, bề mặt mịn, and consistent mechanical properties được yêu cầu.

Cold Rolling Process of Stainless Steel

The cold rolling process involves multiple controlled steps to improve surface quality and dimensional accuracy.

1. Chuẩn bị cuộn cán nóng

• Raw material starts as hot rolled stainless steel coil (black coil)
• Surface contains oxide scale and requires cleaning

2. dưa chua

• Acid treatment removes oxide scale
• Produces a clean metallic surface for further rolling

3. Cán nguội (Room Temperature Reduction)

• Material is passed through rolling mills under high pressure
• Thickness is reduced with high precision
• Strength increases due to strain hardening

4. Ủ (Xử lý nhiệt)

• Restores ductility lost during cold rolling
• Conducted in controlled atmosphere furnaces

5. Thẻ da / Nhiệt độ lăn

• Light rolling process improves:
  • Độ phẳng
  • Bề mặt hoàn thiện
  • Mechanical consistency

6. Hoàn thiện bề mặt

• Final finishes include:
  • 2B (hoàn thiện công nghiệp tiêu chuẩn)
  • cử nhân (ủ sáng, giống như gương)
  • Brushed or polished surfaces

7. Slitting and Recoiling

• Coil is cut into required widths
• Recoiled for delivery or further processing

Key Characteristics of Cold Rolled Stainless Steel Coil

Cold rolling significantly enhances the performance of stainless steel.

1. High Surface Quality

• Trơn tru, lau dọn, and uniform surface
• Suitable for decorative and hygienic applications

2. Tight Dimensional Tolerance

• Thickness accuracy typically within ±0.10 mm
• Ideal for precision fabrication

3. Increased Strength

• Work hardening improves:
  • Yield strength
  • Tensile strength

4. Excellent Flatness

• Minimal waviness
• Better performance in laser cutting and stamping

5. Khả năng định dạng tốt (After Annealing)

• Maintains ductility for:
  • uốn
  • Deep drawing
  • hình thành

Typical Thickness and Width Range

Ghi chú:

• Most common thickness: 0.5 mm – 3.0 mm
• Standard widths: 1000 mm, 1219 mm, 1500 mm

Tính chất cơ học (General Range)

Values vary depending on grade (ví dụ., 304, 316, 430).
