bulged rolls, when subjected to bending during rolling will produce flat sheets. For sheet rolling, normally camber of 0.5 mm on roll diameter is provided. Also during hot rolling, rolls get heated up and bulge out at the center, causing camber of the rolls. This is due to temperature variation between edges and the center of rolls.
In addition, there are different perceptions of "roll wear" amongst rolling mill operators, designers and roll producers. Roll "performance" is a vague term that may concern: mass or length of hot ...
At present, there is a trend of using bucket steel rolls to replace forged steel rolls. The roll of the 6VH billet continuous rolling mill in the Baosteel blooming mill is made of forged semi-steel and forged cast iron with 1.7% ~ 2.4% C, which has good wear resistance and poor hot crack resistance.
Clear Chill Iron Rolls or better known as Definite Chill Iron Rolls have white and super-hard working surfaces, made of graphite-free cast iron.Cast iron is manufactured from eutectic carbide and austentite, which impart the quality of extra hardness and make the resultant metal alloy perfectly resistant to any kind of wear and tear.. Beneath this white iron layer, the …
