Rolling Mill Rolls Description:
1. Consists of shaft and roll sleeve parts, through the
interference fit together
2. Roll sleeve technology is liquid-solid metal binding. The
technology combines the high-alloy and carbon steel to achieve full
metallurgical bonding and to reach the "hard external, tough
inside".
3. High wear resistance
4. Optimum performance behavior
5. Constant hardness
6. Excellent resistance to fracture and spalling.

Rolling Mill Rolls Model:
1: HSS Rolls in Finisher Stand
High Speed Steel Rolls are suitable for finished machine frames,
and the steel passing capacity of high-nickel-chromium-molybdenum
cast iron rolls is about three times higher. It is conducive to
material shape control, reducing rolling accidents, no chipping,
and no cracks.
2: BCI in Roughing-Intermediate Stand
Bainitic Cast Iron Rolls are suitable for roughing and intermediate
rolling mill frames. Their service life is 20% longer than that of
cast iron rolls. They use 42CrMo forged steel shafts. Stable
performance
3: HBHSS in Slitting and Pre-slitting Stands
High Boron High Speed Steel Rolls are suitable for slitting and
pre-slitting frames, and their steel passing capacity is about 2
times higher than that of high-nickel-chromium-molybdenum cast iron
rollers. No chipping or cracking
Rolling Mill Rolls Application:
1. Flat Rolling: Rolling mill rolls are extensively used in flat rolling processes,
where metal sheets or strips are rolled between two rotating rolls.
This process is employed in industries such as automotive,
aerospace, construction, and manufacturing, to produce flat metal
products like sheets, plates, and foils.
2. Shape Rolling: Rolling mill rolls are also used in shape rolling, which involves
the deformation of metal billets or blooms into various shapes such
as bars, rods, beams, and rails. The rolls apply pressure and force
on the heated or pre-formed metal to shape it into the desired
cross-sectional profile.
3. Hot Rolling: Hot rolling refers to the rolling process performed at elevated
temperatures. Rolling mill rolls used in hot rolling operations
must withstand high temperatures and significant loads. Hot rolling
is commonly used for producing steel and other alloys, enabling the
material to be formed and shaped easily.
4. Cold Rolling: Cold rolling is performed at room temperature or slightly below
and is used to improve the mechanical properties, surface finish,
and dimensional accuracy of the metal products. Rolling mill rolls
used in cold rolling processes are typically made of harder
materials and are designed to withstand the high pressures required
for reducing the thickness of the metal.
5. Tandem Rolling: Tandem rolling mills consist of several stands of rolls arranged
in succession, allowing for continuous and efficient rolling of the
metal. Each set of rolls in the tandem mill performs a specific
reduction in thickness or shaping operation, resulting in the
desired final product.
