|Stainless Steel Material:||Stainless Steel||Type:||Work Roller|
|Application:||Cold Rolling Mills||Feature:||Water Proof|
|Roller Sizes:||Customer Required||Shaft/Axle Sizes:||15, 20, 25mm|
The rolls/rollers are of good heat, corrosion, wear-resistant properties, working at high temperature environment on average: 800 to 1200°C, which are used in the steel mills, like CAL (continuous annealing line), CGL (continuous galvanizing line)
ANSI, ASTM, ASME, DIN, GB
Materials: High nickel and high chrome heat resistant alloys, cobalt base alloys, like HU, HT, HK, HP, HW, 24/24NbTiZr, 50Cr/50Ni (2.4813), 1.4865, 1.4849, 1.4848, 1.4410, 1.4059, 1.4841, 1.4845, 1.4852, 2.4879 or as per customer's requirements
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
|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|
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.
