Rolls are often cast using a double pour, in which the outer working surface of the roll is composed of a hard wearing alloy, or corrosion resistant alloy, whereas the interior backing alloy is a lower cost cast iron or steel. Centrifugally cast rolls are used in the paper, printing, plastics, foil and textile industries.

The spheroidal graphite pearlitic iron rolls are widely used in the roughing stands and intermediate stands of various rolling mills. Usually, we make this type of roll by static cast and centrifugal cast. We recommend using centrifugal cast rolls for better performance when the groove in the roll .
It is always guaranteed that machines used in industry have a permanent level of high quality and robustness, are easy to maintain and have a reliable supply of spare parts. This means that even used industrial equipment for start-ups are a useful investment to ensure that the required productivity is met.
Horizontal Machine (RollerTYRe) This machine (Fig. 2); is used to make tubular castings usually where production quantities are high. It is not the same as the pipe casting machine. The horizontally rotated mold is composed of four parts: 1) the shell, 2) t-hecasting s~out (the end of the mold into which the molten metal i~ poured), 3) the

Typical parts made by this process are pipes, flywheels, cylinder liners, and other parts that are axi-symmetric.It is notably used to cast cylinder liners and sleeve valves for piston engines, parts which could not be reliably manufactured otherwise.. Features of centrifugal casting. Castings can be made in almost any length, thickness and diameter.
Double poured and centri- fugally cast rolls are also known as Duplex Rolls. 6.5 (h) Tbingsten carbide rolls: The demands of modern high speed Rod Mills having No-Twist Finishing Blocks brought about the develop- ment of special roll materials particularly tungsten carbide as an ideal roll material.

Kubota chose a centrifugal casting method for manufacturing rolling-mill rolls in 1961, earlier than any other manufacturer worldwide. In 1991, Kubota began producing the world's first centrifugal cast composite rolls with an outer layer made of a high-speed tool steel material with high resistance to wear and surface-roughening performance.
Providing investment castings (lost wax castings) is our purpose. We build the tool plus make and machine the castings, regardless if it's a single-piece order or a high-volume 10,000+-pieces-in-a-week necessity. We offer 100 different alloys. We've cast pump and valve parts plus many other parts.
