Application: plate mill, finishing stand of hot strip mill, steckel mill

Description: These rolls are spun cast with a highly alloyed shell consisting of nickel, molybdenum, and chromium. The core can be grey iron with flake graphite, iron or spheroidal graphite iron depending on the mill requirement of neck strength.

TECHNICAL INFO

Manufacturing process: centrifugal casting

Hardness: 70-85 HSC

Chemical composition, %:

Application: plate mill, finishing stand of hot strip mill

Description: These rolls are spun cast with a working layer which consists of a very highly alloyed white iron with no free graphite in the structure. The refined iron and Cr carbides give excellent wear resistance to this material.

TECHNICAL INFO

Manufacturing process: centrifugal casting

Hardness: 65-85 HSC

Chemical composition, %:

Application: plate mill, finishing stand of hot strip mill

Description: These rolls are spun cast with a working layer which consists of uniformly distributed complex carbides of vanadium, tungsten, niobium and molybdenum in the martensitic matrix ensures the uniform hardness of the working layer. HSS rolls have high hardness and good wear resistance at high temperatures.

TECHNICAL INFO

Hardness: 70-85 HSC

Chemical composition, %:

Applications: medium and heavy sections mills, roughing stands of hot strip mill

Manufacturing process: static casting

Description: These rolls are special hyper-eutectoid steel rolls alloyed with nickel, chromium and molybdenum. The extra carbon and special alloys give extra wear resistance and strength.
These rolls are statically cast and undergo a special high temperature heat treatment process of double annealing followed by tempering cycles to give a microstructure consisting of a fine pearlitic matrix with spherodised / broken carbide.

TECHNICAL INFO

Manufacturing process: static casting.

Hardness: 40-55 HSC

Chemical composition, %:

Application: bar and rod mills, light and medium section mills, narrow-strip mills, seamless tube mills

Description: Nodular irons belong to a group of cast iron in which most of the carbon crystallises as spherical particles known as graphite nodules. A wide range of properties may be obtained by adjusting the three major alloying elements: Cr, Ni, and Mo. The low nickel grade (ferritic grade) provides optimal hardness with high strength and toughness. The medium nickel grade (pearlitic iron) has higher surface hardness necessary for intermediate and finishing. The high nickel and molybdenum grade (bainitic/acicular iron) provide excellent mechanical properties at a high working temperature in terms of strength, toughness and hardness.

TECHNICAL INFO

Manufacturing process: static or centrifugal casting

Hardness: 40-80 HS

Chemical composition, %:

Application: heavy-section and rail mill

Description: Chromium with nickel and molybdenum results in a high level of hardenability and wear resistance. High chrome iron sleeves are heat-treated to produce discontinuous, highly wear-resistant iron/chromium carbides in a matrix which can be varied from spheroidal pearlite through to high hardness martensite according to the requirements of the application. The high hardenability enables the hardness to be made virtually consistent across any section.

TECHNICAL INFO

Manufacturing process: static casting
Hardness: 65-85 HSC

Chemical composition, %:

Applications: plate mills

Description: Backup rolls weighing 60-230 tones made of alloy-forged steel with Cr content of 1,40-5,50% have an excellent combination of metallurgical and physical properties such as a compact porosity-free microstructure; good ductility and toughness values; high resistance to fatigue, wear and thermal cracking. High physical and metallurgical properties are to be achieved throughout the optimal combination of pure steel, forging ratio and heat treatment processing.

Hardness: 50-70 HSC

Application:  plate mill, hot strip mill, cold rolling mill

Description:  Rolls for their smooth rotation as well as for resistance to different forces need ‘bearings’.  Roll bearings are to meet the basic need of the rolling mill which is the smooth rolling of the steel products. They are friction reducing devices which provide support to the rolls for effective rolling with minimum of energy loss. The bearings are designed to withstand high rolling loads, heavy shocks, varying speeds, and high temperatures.

The housing of a work roll or backup roll bearing is known as roll chock or simply chock. Chock is the basic part of a rolling mill. It is mounted in the window of the roll stand housing between the posts with a small clearness. The roll stand housing encloses and supports the chock assembly. The chock also prevents scale getting into the roll neck bearing.

TECHNICAL INFO

Manufacturing process: steel casting.

Hardness: 145-190 HB.

Weight: max 35MT.
