Introduction<\/strong><\/span><\/h2>

In modern stainless steel production, cold rolling mills play a critical role in determining product quality, surface finish, and operational efficiency. Among all components, \u0644\u0641\u0627\u0626\u0641 \u0627\u0644\u0639\u0645\u0644<\/strong> <\/a>are the most essential yet vulnerable parts of the system. Frequent failures such as roll spalling, cracking, and fracture<\/strong> can severely disrupt production and increase costs.<\/p>

A 950mm six-high, six-stand continuous cold rolling mill in China experienced significant roll failures after commissioning. Through systematic analysis and targeted improvements, the plant successfully reduced failure rates and improved overall efficiency. This article explores the root causes, failure modes, and practical solutions<\/strong> for cold rolling roll failures.<\/p>

1. Three Major Failure Modes in Cold Rolling Rolls<\/strong><\/span><\/h2>

1.1 Roll<\/a> Spalling (Flaking)<\/strong><\/span><\/h3>

Spalling is the most common failure mode, accounting for over 70% of work roll failures. It appears as surface material peeling, forming pits that damage strip quality.<\/p>
