Roller Leveling Cut-To-Length Lines
Butech Bliss builds levelers for a wide range of applications. The solution we propose for any given project depends upon the customers requirements. All of our levelers include hydraulic flight adjustment and our self calibrating feature. We offer levelers with single work roll sizes, multiple cassette roller levelers with different roll sizes for use in one common housing and we offer our patented Synergy® Leveling System which combines two different work roll sizes in one cassette. The Synergy® Leveling System broadens the product range of the leveler without requiring the operators to change from one cassette to another when certain product ranges are being processed.
Most applications include individually driven work rolls which offer several advantages when compared to other drive systems. These advantages include:
- the ability to create inter-roll tension
- the ability to continue running should a particular motor or gear reducer fail
- reduced spares inventory cost because each roll is driven by a common fractional horsepower motor and gear reducer when compared to a single motor, reducer and pinion arrangement.
Application: Cut-To-Length lines, Multi-Blanking lines, and discrete sheet and plate levelers
Shape Improvement: 50 to 100 I-units dependent upon incoming shape
Coil Memory: Levelers work the top and bottom half-thickness of the material such that shape improves and differential stresses are minimized.
Attributes: Removes coil set, cross bow, wavy edges and buckles; critical surface product requires six-high configuration and may result in increased maintenance; high strength steels are a limiting design factor; does not provide surface conditioning capability
Use: Basic laser/plasma operations
Stretch Leveling Cut-To-Length Lines
Butech Bliss designs and builds Stretch Level Cut-To-Length Lines for every customer’s specific and oftentimes unique requirements. Whether you are looking for a discrete plate stretcher or a coil-to-sheet stretcher we have the engineering capabilities to meet your needs. We’ve supplied over 150 Stretch Levelers for processing everything from aluminum plates for the aircraft industry, to extruded products, treadmill plates, hot rolled, HRPO and cold rolled steels including low carbon and high strength steels.
Our Stretch Leveling Cut-To-Length Lines include gripper heads specifically designed for your application. Some include a replaceable, economically priced, commercially available gripper pad that allows changeover between various products without the need for downtime to clean or replace the gripper head assemblies. Some include a metallic gripper and some include interchangeable gripper heads so either type of head can be used in the same stretcher.
Butech Bliss can provide wedge type grippers or direct acting grippers. Either style is capable of operating at multiple pressure settings so adjustments can be made to prevent edge distortion when processing narrow light gauge product or surface marking when processing soft, coated materials like hot dipped galvanized steel. No need to add shim plates on narrow product with a Butech Bliss Stretch Level Cut-To-Length Line. Our wedge style grippers are especially effective at preventing slippage while also avoiding the potential for edge distortion.
Our Stretch Level Cut-To-Length Lines are designed to process multiple materials and material characteristics on the same line. The control system portal is an HMI based design that enables easy setup changes and recipe driven menus to vary stretch, hold and retract cycle times, stretch speeds and clamping pressures according to specific product requirements. Recipe driven menus increase productivity and product consistency because the settings can be quickly recalled when repetitive runs of the same product are required.
When Butech Bliss’ Stretch Leveling Technology, Synergy® Leveling System, unique Brush Roll Scale Collection System and direct drive shear technology are combined, you know you have all the tools you’ll ever need to meet your customer’s requirements.
Application: Cut-To-Length lines (lines include a backed up, close center leveler(s) to correct surface-to-surface length differential defects and to pre-condition the material for stretch leveling)
Shape Improvement: 800 to 1000 I-units
Coil Memory: Stretch leveling changes the crystalline structure of the metal through the use of tension. This change reduces internal stresses and the material remains flat when subjected to cutting operations such as laser or plasma cutting processes.
Attributes: Removes coil set, wavy edges and buckles; cannot change or improve surface characteristics; designed to process a wide range of products and material properties, including high-strength steels; low initial costs and low operating costs; some material width neck down does occur as a result of the stretching process.
Use: Basic and difficult laser/plasma cutting operations and welding applications; excellent for processing checkered floor plates.
Temper Mill Cut-To-Length Lines
The Butech Bliss 2 Hi or 4 Hi temper mill solution uses the world famous Bliss technology supplied to mills throughout the world. The temper mill solution is the ultimate when stress equalized and surface improvement or high productivity is required. A temper mill line is a high production line with a rotary or flying shear. The stacking system is designed to accommodate sheet or plate on the fly. The temper mill line includes levelers located after the mill for further shape correction. When compared to the other cut-to-length lines, the productivity is unequaled. The Butech Bliss temper mill features a hydraulic roll force cylinder that is the industry standard. With more than 60 temper mills in our history, why not let Butech Bliss be your mill provider.
Application: Cut-To-Length lines or standalone Temper Mill
Shape Improvement: 800 to 1000 I-units
Coil Memory: Temper mill elongations and mill compressive forces produce equalized stresses top and bottom to produce a stable product for downstream processing; the leveler(s) extend portions of the material to further improve shape; the material remains stable during burning, welding or forming.
Attributes: The temper mill will improve flatness, provide a means to change surface finish and modify the metallurgical properties of the material; leveler(s) remove coil set, cross bow, wavy edges and buckles; mill requires higher initial investment and long-term operating costs when compared to alternate technologies
Use: Basic and difficult laser/plasma-cutting operations and welding applications.
Multi-Blanking or Slitting Lines
Small accurate blanks can be produced by slitting the width and then cutting the length in a cut-to-length line. When they are combined in the same line Multi blanking is born. Floor space is less but more importantly response time to customers is minimal because you can produce a large number of blanks in a small amount of time.
Butech Bliss lines have the slitter located directly after the leveler and ahead of the looping pit. This strategy means the slit mults can spread out ahead of the shear and stacker. This feature produces results such as locating the side trim scrap chopper to be in an accessible area, (before the pit) and most importantly the stacker can be robustly designed and maintenance free.
Multi blanking requires feeding of the slit mults through a shear either onto a belt run out table if inspection is desired or feeding the mults through the shear directly into the stacker.
Butech Bliss Blanking Advantages:
- Minimizes induced cross bow
- Improved slit cut edge quality
- Improved shear cut quality
- Improved blank flatness
Our hydraulic levelers or our optional Synergy® levelers are designed to remove flat rolled strip shape defects such as coil set, crossbow, edge wave, center buckle and twist. An enhanced menu driven operator interface allows simple graphical controls and a recipe system for quickly saving and recalling the best shape correction settings for a particular product. This HMI based control package is both intuitive and operator friendly. Our optional Synergy® leveler features two work roll sizes in one machine, individual drives and a quick change cartridge system. Both leveler types include an innovative feature for work roll and back up roll removal to assure quick and easy maintenance, as well as a zero nesting feature which provides automatic self-calibration assuring quick and accurate leveling and repeatability with each work roll change. Additional features include quick change cassette system and a self-contained scale collection system for hot rolled steel applications. The slitter technology available encompasses a wide variety from one fixed arbor and one jack moveable arbor to the super precision double ecentric type locating the slitter in the line so that it can run at a constant speed improves both knife life and cut edge quality. The slitter heads are quick change type with offline set-up stations. This location also means no chance of inducing camber as the mult “fan out” is under no tension in the pit.
