  OUR PRODUCT:- INDEFINITE CHILLED ROLLS  
     
     
  Indefinite chilled rolls are cast iron based rolls alloyed with nickel, chromium and molybdenum having a matrix of pearlite and carbide with flake graphite. These rolls are used primarily for section rolling.the matrix structure varies from fine pearlite to bainite depending on the alloy content. The desired hardness is obtained by changing the carbide/graphite. The material has very good thermal properties used in finishing stands of rod mill.the rolls are to ensure minimum sacrifice of clear chill while achieving maximum functional depth.  
     
     
 
Chilled to graphite being smoother, the hardness associated with the indefinite chilled structure allows deeper grooving. indefinite 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.
 
 
     
     
  HARDNESS: Chilled rolls of this type have hardness up to about 70 shore °c can be grooved for use in roughing and finishing stands, for processing sections such as t-bars and u-sections, and for roughing and intermediate rolls of wire and rod mills.
