chrome plated skin pass mill rolls

Hard chrome plating of work rolls for cold rolling and

From the standpoint of wear resistance, what would be considered a significant thickness of hard chrome plate, will be very close to its adhesion strength limit, thus will easily flake off. Chrome works fine only for low pressure operations where wear is the main factor such as temper mill rolls, skin pass rolls and idle rolls.

Substitution of chrome plating for the rolls of skin-pass

The aim of the CrFreeRolls project to find a solution to a threat arising in cold rolling and especially in skin-passing. For long hard chrome plating has been introduced to enable high consistency of the roughness of the strip after skin-pass.

Chrome Plating of Work Rolls on Aluminium Cold Rolling

The life of Work Rolls or the time between subsequent regrindings can be reduced by using Rolls of higher hardness and higher chrome composition in the material of the Rolls. The hardness should be as high as possible preferably 65 HR'C'+. Hardchrome plating would not help as the plated layer is very thin and would come out after every regrinding. Also it can lead to failure of Rolls due to
