Stainless Steel High Precision Forged steel work rolls for Cold-rolling Mills
Work rolls for cold rolling are made of alloyed steels.
The complex of heat treatment provides for the necessary mechanical properties of the hardened layer due to creating a uniform fine-grain structure.
Final stabilizing heat treatment is intended to reduce and equalize the residual thermal stresses.
Guaranteed features of forged steel work rolls for cold rolling
High and uniform hardness after hardening (within 1-2 HSD over the barrel)
Effective layer depth over the radius (20-40 mm)
High thermal fatigue resistance during overall and local heat-up, increased heat resistance (high hardness is maintained for a long time under steady-state thermal conditions of the roll);
Resistance to surface defects, cracking, lamination, scabbing, spalling, tearing, etc.
High surface quality after heat treatment and machining
Favourable distribution and minimal value of residual stresses after hardening and machining
Absence of metallurgical defects and impurities
Absence of flakes, coarse carbide clusters, carbide network, large-pattern acicular martensite and other macro- and microstructural defects
Absence of machining defects
Specification
| Item | MC3 forged work roller steel rolling mill |
| Handcrafte | furnace rolls are comprised of statically cast trunions (ends) welded to a centrifugally cast roll body with our unique locking mechanism. |
| Temperture | can perform in high temperture |
| Advantage | Our dry rolls are comprised of statically cast trunions (ends) welded to a centrifugally cast roll body used in a tunnel furnace |
| our dry rolls will provide abundant fuel savings through reduced heat loss in the furnace |
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.
DESCIPTION of Work Rolls or Backup Roller:
1) Material: Alloy Steel, Alloy Iron, Ductile Iron namely 9Cr3Mo,
70NiMoV etc.
2) Standard: GB, AISI, SAE, ASTM/ASME, EU, AS/NZS etc
3) Size: According to clients' drawing or design needs
4) Hardness: based on design specification
5) Chemical Composition and mechanical property: as specified.
Packing and preservation
Packing and preservation methods depend on the contract conditions and on the climatic zone where the rolls are going to be supplied, as well as on the transportation and storage conditions.
The items ready to be shipped are covered with a preservative coating – several layers of primer and enamel.
The roll necks are wrapped into anticorrosive paper with polyethylene coating and into waterproof paper.
Storage and service
The rolls should be stored at a non-heated storage, on special shelves, resting on their necks.
Ageing or periodical low tempering is strongly recommended during roll operation life.
we can do various customized work rolls ranging in different sizes
and processes. please feel free to make any enquiries accordingly.
