PRECISION HYDRAULIC CORRECTIVE LEVELERS
Precision Corrective Levelers
ALCOS designs and manufactures a complete range of precision corrective levelers, in standard 4HI configurations or 5HI and 6HI roll configurations for surface sensitive materials.
The ALCOS 6-HI LEVELER has an additional bank of full-width intermediate rolls between the back-up and work rolls on both top and bottom roll banks, to prevent marking of soft or highly-polished strip surfaces.
ROLL SIZES: From 1″ diameter to 7″ diameter work rolls with up to seventeen or nineteen work rolls.
WIDTH CAPACITY: up to 96″ wide materials.
Our Corrective Levelers Features
Back-Up Roll Assemblies
The back-up roll assemblies (flights) provide both vertical and horizontal support for the work rolls.
The back-up rolls consist of a unique bearing arrangement that can withstand the radial loads coupled with axial thrust. They are specifically ground crown and blended radii to reduce marking of the work or intermediate rolls they support. One bank of work rolls has manually adjustable back-up rolls for set-up purposes only, the other bank has remote-controlled, motorized, back-up roll adjustment for use during operation.
All flights are actuated by independent entry and exit hydraulic cylinders which allows the operator for maximum flexibility during operation.
The ALCOS precision ground work rolls are made from a special alloy steel, induction hardened for the optimum combination of core toughness and controlled surface hardness and depth. All work rolls are precision ground to ensure effective control and positioning.
Critical surface applications may require the work rolls to be chrome plated. All work rolls rotate in bearings.
Work Roll Drive
Each work roll is driven at exactly the same speed by the transmission system through a Alcos custom universal joint drive system.
The drive comprises of a gear reducer and splitter gearbox. All shafts, pinions, and gears are made from hardened alloy steel for maximum performance.
Centralized automatic lubrication system to all bearings ensures even lubrication of all essential parts.
Free standing console house operator push buttons, joysticks and large touch screen display with multi-color graphic readout showing positions of each flight of back-up rolls. All settings can be saved and recalled for easy operation. The adjustments can be recalled automatically.
