Casting / Forged Alloy Steel Rolling Mill Rolls for Cold Rolling Factory

The raw billet material of Alloy Steel Rolling Mill Rolls 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 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.

The Material type: 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.

Production Process: Forging—heat treatment—machining (rough machining and finish machining)

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.
