High Wear-Resistance Working Rolls For Finishing Machines Anti-rust
Alloy Steel Roller With ASTM Standard
Alloy cast steel roll is manufactured
with high quality steel molten by arc furnace, due to the advanced
casting and thermal traetment technique, such roll is of very high
intensity. Owing to its excellent performances of anti-heat crack,
tenacity and wear-resistance,t is appropriate to be used for rough
and intermediate section steel rolling machine, heat rolling strip
steel rough rolling machine stand and uesd as back-up roll for heat
rolling strip steel. Its metallographic structure is made of
pearlite or temper sorbite. The alloy steel rolls are widely used
in the BD mill and roughing stands of heavy section mills,
universal mills and rail& beam mills. This type of roll often
has deep grooves in the roll body, so we make it by static cast.
Due to the low carbon in the chemistry, we can hardly see graphite
and carbide in the microstructure.
Raw Material: Carbon steel, C-Mn steel, alloy structure steel,
alloyed tool steel, cold roll steel, steel for pressure vessel,
Carburizing steel, die steel, stainless steel and so on.

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
we can do various customized work rolls ranging in different sizes
and processes. please feel free to make any enquiries accordingly.
