Cold-rolled Strip Coils of pure titanium are manufactured using a Sendzimir mill. Although a Sendzimir mill is suitable for manufacturing the cold-rolled strip coils With excellent surfaces, productivity is low, so, there is a desire to manufacture the Cold-rolled strip coils that do not require excellent surface by cold tandem rolling Mill. However, a surface defect called micro-cracks, occurs if the strip without the Problem by Sendzimir mill is rolled out by cold tandem mill. In this report, the gen- Eration mechanism and the prevention method of micro-cracks in cold tandem roll- Ing are examined to establish the higher productivity cold tandem rolling technol- Ogy of pure titanium.
