Forged Heavy Duty Work Mill Embossing Rolls Stainless Steel Pin Squeeze Operating Rollers
Product Details:
In metalworking, rolling is a metal forming process in which metal
stock is passed through one or more pairs of rolls to reduce the
thickness and to make the thickness uniform. The concept is similar
to the rolling of dough. Rolling is classified according to the
temperature of the metal rolled. If the temperature of the metal is
above its recrystallization temperature, then the process is known
as hot rolling. If the temperature of the metal is below its
recrystallization temperature, the process is known as cold
rolling. In terms of usage, hot rolling processes more tonnage than
any other manufacturing process, and cold rolling processes the
most tonnage out of all cold working processes.Roll stands holding
pairs of rolls are grouped together into rolling mills that can
quickly process metal, typically steel, into products such as
structural steel (I-beams, angle stock, channel stock, and so on),
bar stock, and rails. Most steel mills have rolling mill divisions
that convert the semi-finished casting products into finished
products. There are many types of rolling processes, including ring
rolling, roll bending, roll forming, profile rolling, and
controlled rolling.
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 body is not too deep. With more alloy added in, we can get a microstructure consisting of spheroidal graphite, pearlite and primary carbide type M3C up to 30%. Meanwhile, the core of the roll still keeps very strong with a great amount of spheroidal graphite in the matrix of ferrite.When the groove in the roll body is very deep, we recommend using rolls static cast with groove to achieve a low hardness drop between the body surface and bottom of the groove.

Produce & Dlivery:
Slabs are the feed material for hot strip mills or plate mills and
blooms are rolled to billets in a billet mill or large sections in
a structural mill. The output from a strip mill is coiled and,
subsequently, used as the feed for a cold rolling mill or used
directly by fabricators. Billets, for re-rolling, are subsequently
rolled in either a merchant, bar or rod mill. Merchant or bar mills
produce a variety of shaped products such as angles, channels,
beams, rounds (long or coiled) and hexagons.
Application:The spheroidal graphite pearlitic iron rolls are widely used in the roughing stands and intermediate stands of various rolling mills.
we can do various customized work rolls ranging in different sizes
and processes. please feel free to make any enquiries accordingly.
