High Precision to 0.01mm Heavy Load Capacity Built-up Sleeved Backup Rolls

The first roll for hot-rolling mills were produced from ingots weighing up to 40 tons at Uralmashplant in 1934. The plant began producing large ingots, weighing 60 tons and more, in 1935-1936, which allowed to manufacture large backup rolls for rolling mills.

Because of exceptionally high requirements to the quality of metal used for production of cold mill rolls, re-tooling and modernization of the production plant were carried out by the 1940. Since then, rolls for cold-rolling mills have become an integral part of Uralmashplant's assortment.

Uralmashplant is rated among the leaders at the world's roll market due to renovated production capacities.

Based on the manufacturing facilities, the plant has mastered production of a new type of rolls with 3 to 5 percent Cr content, as well as higher content of alloying elements, which allows to make the service life of rolls 1.5 to 2 times longer.

 

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

 

 

Rolling mill for hot rolled or cold rolling metal sheet or billets etc.
 
Different functions of rolls rollers for steel mills:
Work rolls
Backup rolls - are intended to provide rigid support required by the working rolls to prevent bending under the rolling load.
Rolling balance system - to ensure that the upper work and back up rolls are maintained in proper position relative to lower rolls.
Roll changing devices - use of an overhead crane and a unit designed to attach to the neck of the roll to be removed from or inserted into the mill.
Mill protection devices - to ensure that forces applied to the backup roll chocks are not of such a magnitude to fracture the roll necks or damage the mill housing
Roll cooling and lubrication systems.
Pinions - gears to divide power between the two spindles, rotating them at the same speed but in different directions.
Gearing - to establish desired rolling speed.
Drive motors - rolling narrow foil product to thousands of horsepower.
Electrical controls - constant and variable voltages applied to the motors.
Coilers and uncoilers - to unroll and roll up coils of metal.
 
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.
 
Design features:
The sleeve makes the working surface 2 or more times thicker
Roll spindle can be used more than once
 

Guaranteed features of built-up (sleeved) backup rolls

Required uniform hardness of the sleeve

Reliability of sleeve fit on the shaft

No tendency towards cracking or barrel spalling

No metallurgical or structural defects

Minimal level of residual stress

No design flaws impairing the roll performance

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