Back up Rolls
Rolls are manufactured from degassed steel by means of a vacuum process that presents a high level of purity. Forging occurs in hydraulic presses to guarantee high toughness. They are used in continuous hot-strip, steckel-type and cold strip mills, withstanding the most severe rolling conditions. Product development guarantees a performance which is far superior to that of cast back-up rolls. The microstructural homogeneity of these products allows for applications involving high hardness ranges and high resistance.
Rolls for Cold Roll Application
These are manufactured from degassed steel by means of a vacuum process that presents a high level of purity. Forging occurs in hydraulic presses to guarantee high toughness. Heat treatment is carried out by a double-stage progressive induction process.
Rolls for Hot Strip Application
Manufactured in an induction furnace, rolls are cast by centrifugation, which results in excellent structural homogeneity. They are used in the initial and final finishing stands, containing a high-strength gray cast iron or nodular cast iron core, which meets current flexion and displacement requirements of high-productivity rolling mills. Centrifuged cast rolls for finishing stands in hot strip mills are manufactured according to the most modern technologies available today.

Hydraulic Clamping Nuts
Amtec Hydraclamp – Canada
Pyramid Technomate is Authorized Distributor of Amtec-Hydraclamp in India,
We offer high-pressure clamping and tensioning solutions, including hydraulic nuts, pre-tensioning devices, block nuts, step nuts, and related accessories.
Amtec Hydraclamp™ Hydraulic Clamping Nuts are suitable for steel slitters, side trimmers, choppers and roll-forming lines, which all benefit from the exceptional safety, convenience, efficiency and highly controllable clamping.
Amtec Hydraulic Nuts safely and conveniently replace major mechanical nuts on all types of metal processing lines by eliminating sledge hammers and heavy wrenches, which cause much of the strain and physical injury to the set-up personnel. Bearing damage from hammering nuts is eliminated with Amtec Hydraclamp™ Hydraulic Clamping Nuts. Our piston activated hydraulic nuts provide positive, controlled clamping force applied with every installation to ensure reliably accurate tooling set-ups. Using hydraulic energy to create clamping force eliminates friction on threads, which is the prime cause of early thread wear.
F-Type
All Amtec F-Type Nuts are activated by grease to suit operating specifications. Amtec F-Type Nuts offer self-aligning, annular thrust rings, which create a high force lock to prevent unthreading once pressure is applied.
The extreme internal pressure pushes the thrust ring against the mating tooling and simultaneously forces the nut body to locate against the arbor or shaft threads. Therefore, all threads may be right hand rotation regardless of whether the arbor or shaft rotation is clockwise or counterclockwise. Amtec will custom manufacture all F-Type Nuts to any existing thread form, regardless of thread hand, provided the thread form conforms to international standards.
K-Type
All Amtec K-Type Nuts are actuated by pistons pressurizing a grease medium. Amtec K-Type Nuts offer self-aligning, annular thrust rings that create a high force to prevent unthreading once pressure is applied. The extreme internal pressure pushes thrust rings against the mating tooling and simultaneously forces the nut body to locate against the arbor or shaft threads. Therefore, all threads may be right hand rotation regardless of clockwise or counterclockwise shaft or arbor rotation.
Amtec will custom manufacture all K-Type Nuts to any existing thread form, regardless of thread hand, provided the thread form conforms to international standards. Amtec K-Type Nuts are manufactured from 4140 chromoly steel to withstand up to 700 bar (10,150 PSI) without stress or fatigue. All Amtec K-nuts are available with indicator pins that pop up when clamping pressure is met.
