Cast iron chilled rolls manufactured by us is made of best quality cast iron. These are frequently used in several industries like food processing industries, textile industries, paints, soap, detergent, pharmaceutical industries, rubber and paper industries. The shafted cast iron chilled rolls are well-marked for their brilliant features. The cast iron indefinite chill roll is manufactured by adding niobium in the compositions. All these products are highly durable and performance oriented. Consequently, we are among the prominent suppliers of cast iron chilled rolls.

Rolls are tailormade products and therefore need careful production planning. Rolls are cast in chiller mould with a controlled allowance for contraction and machining. It is therefore necessary to have a mould of the desired size. A new mould is required to be made if oue is not available. After obtaining a order from a customer and a drawing for the reequired rolls, a method drawing for casting is made, according to which the mould for casting of the rolls is made. Melting of metal is carried out in any of the several induction melting units available as per requirement of metels. The melting charges are selected as per required chemistry of metal. Upon melting, samples are analyzed and necessary adjustments for various alloying elements made through additions of Ferro-alloys. Fracture tests are made and temperature measured to control the same through Immersion Pyrometeres. Metal is poured in the moulds through geared ladles of various capacities in pre-determined time to ensure clean metal in the mould.

The structure consist of graphite nodules in the matrix of bainite. These rolls have high hot strength combined with good wear resistance. Sufficient water cooling is a must for satisfactory

These Metal Rolls have hard alloy iron on the working layer and the core is either made of soft grey iron or nodular iron as application demands. The matrix generally is bainitic with equal distribution of carbides and graphite on the shell. Due to the Nodular core and highly alloyed surface these Rolls have excellent mechanical properties, strength, high wear resistance, good surface finish and resistance to shock/thermal/mechanical loads. These Rolls are produced by spin and static cast together. Application of DPIC Rolls include : Wire rod finishing rolling. Flat products rolling in Hot strip and Plate Mills. Cold rolling of non-ferrous sheets. Size limitation : Maximum : 600 mm diameter Minimum : 150 mm diameter

These rolls are spun cast with highly alloyed shell consisting of Nickel, Molybdenum and Chromium. The Core can be grey iron with flake graphite, iron or spheroidal graphite iron depending on the mill requirement of neck strength.The shell micro structure consists of bainiticmartensitic matrix with carbides and fine graphites. The micro structure offers excellent surface finish to rolled product along with bruise and crack resistance due to presence of graphite which can be altered depending upon the rolling condition.

The Working surface of clear chill rolls shows the white graphite free structure consisting of eutectic carbide and transformed austenitne. This gives a hard layer which confers good resistance to wear. Flake graphite is embedded in a matrix of pearlite containing about 0.08% of combined carbon. Compared to grey iron, white chill iron is less soft, strong & incapable of withstanding high dynamic stress, but owing to its greater hardness, has better wear resistance, and has high compressive strength. These make excellent work rolls for two, three and four mills, turning out of high grade ferrous and non-ferrous sheet and strip or section.

Chilled Iron Rams (Pistons) are chilled casted to get 100% Scratch Proof surface for longer life of Hydraulic Seals. The surface of the Rams is hard enough to withstand almost any climate and yet smooth on seals for long life. Chilled Rams are free from all defects like sand fusion, blow holes, piping & cracks etc. We are manufactured Chilled Rams are having protected centres & having up to 0.01 micron finish These Rams are capable to bear external specific pressures. The hard and grinding mirror polished surface maintains the high hydraulic oil pressure together with the circumstantial seals. Chilled Iron Rams (Pistons)take the pressure of the hydraulic fluid on one side and pass them on to the forming tools on the other side for these applications; Chilled Cast Iron or Chilled Spheroidal Cast Iron have proven their reliability for decades. These Hydraulic RAMPiston are made one piece, flange fitted or fabricated along with drilling operation
