Special Cast Steel ndefinite chilled iron rolls are cast highnickel grain rolls with fine deposits of graphite on the surface. The hardness of these rolls can be changed by adjusting the chemical composition or by changing the casting method, making it possible to adapt the roll hardness to particular appliions. Because of the presence of graphite, these rolls have a strong resistance to ...

Kay Jay Chill Rolls is manufacturing and exporting chilled cast iron rolls or mill rolls for the flour mills, animal feed mills, oil seed crushing, cracking flaking, grain cereal mills, rice flaking ...
Cast steel rolls can be divided into two egories: steel rolls (carbon content %) and semisteel rolls (carbon content ). Steel rolls have low carbon content, so their hardness is low, and their structure is generally composed of iron.
Cast iron mill rolls, due to their fracture toughness and tribological properties, are the most often applied at hotrolling in the last rolling stands. This results from the smallest dynamic loads of such rolling stands and the decisive influence of the surface quality of these tools on the surface quality of the rolled product. An improper microstructure of rolls can lead to their premature ...

Today, Thai Tech Steel (2013), with its brand of TTS ROLLS, is the leading roll manufacturer in South East Asia. We produce stateoftheart ductile nodular cast, acicular, steel base adamite and double poured centrifugal cast products for various appliions including bar wire rod, light medium section, seamless tube, rings, kocks, sleeves and work rolls for hot strip and plate mills ...
cast iron rolls. The carbon is present in the form of spheroids or nodules which increases the ductility and makes the roll more resistant to fracture. Nodularisation is achieved by the addition of calcium silicide and magnesium or cerium. The nodular structure of carbon imparts better tensile strength than that of cast iron along with better wearing properties. However, such rolls are more ...
Work rolls for the Finishing Stand of Hot Strip Mills Centrifugally cast. Manufactured in induction furnaces, they are centrifugally cast resulting in an excellent structural homogeneity They are used in early and finishing stands with high resistance gray cast iron or nodular cast iron cores, thus meeting the present bending and shifting requirements of high production rolling mills. A wide ...
Mastiion is done in a tworoller rubber mixing mill, having two horizontally placed chilled cast iron rolls driven by a motor of suitable horsepower depending on the production capacity. Suitable heating and cooling arrangements are provided by steam and water lines in the hollow rolls. These two rolls are revolving toward each other with a differential speed, the friction ratio being ...

Work rolls for strip mills are generally forged steel while the backup rolls are cast steel. In a bar mill appliion, the rolls are generally cast iron or specialty alloy steel designed to withstand the particular heat and rolling appliion . In many cases, roll necks can be remachined to match the design for a different mill. Contact Casey Equipment for a quote on used rolling mill rolls ...
Bainitic and bainitic / martensitic nodular iron are nodular grades alloyed with Cr, Ni, and Mo with higher Cr and Ni contents. Compared to pearlitic irons, acicular irons show higher strength, toughness and wear resistance. The rolls can be cast static or spun cast depending of the size of the working layer and the mill conditions.
