From roughing mill to finishing mill, the impact load gradually decreases, while rolling speed, dimensional accuracy and wear resistance requirements keep rising. The roll design shifts from **high toughness priority** to **high hardness & high wear resistance**. Solid rolls are widely adopted for roughing and intermediate stands, while roll rings

In cold rolling production, rolling rolls directly determine three core production indicators: strip steel output, plate surface quality and steel consumption per ton. Various roll defects occurring during cold rolling will cause batch product downgrade or scrap, reduce product yield, and even lead to severe equipment damage in extreme cases.
