Definite Chill Rolls

   

Definite chilled iron rolls have a high-hardness layer of white cast iron at the surface. a fine surface finish is required, rolls for hoop and skelp mills must be chosen with particular regard for strength and hardness, primarily so the rolls will match the roughing, intermediate, and finishing stands.these rolls has high compressive strength.

Chilled to graphite being smoother, the hardness associated with the definite chilled structure allows deeper grooving. definite chilled rolls are superior in biting performance and have enough strength and resistance against thermal shock occuring at the time of accident in the rolling operation compared to our chilled rolls.
