STRIP PROCESSING – SOLUTIONS TO MEET THE HIGHEST THROUGHPUT AND QUALITY DEMANDS
Strip processing lines from Unisons stand for high-performance and cost-efficient strip processing that fully meet the demands of high-end markets such as the automotive industry.
PICKLING LINES – CLEAN AND SCALE-FREE SURFACES FOR OPTIMIZED DOWNSTREAM PROCESSES
Modularly designed continuous pickling lines from Primetals Technologies are known for their efficiency, economic operation and use of advanced technologies such as i-Box pickling.
Continuous and push-pull pickling lines are equipped with compact scale breakers, the latest welders and turbulent pickling systems that are designed and optimized on the basis of extensive operational experience. Customers have the choice of different pickling concepts (i-Box, turbulent tank, shallow bath tank) to meet their specific productivity requirements or preferences. Accurate strip and pickling control, fast and stable processes, and precise strip tracking are decisive factors for optimized pickling operations. The assurance of highest strip surface quality and cleanliness is paramount in importance to ensure reliable and cost-efficient downstream processing.
CONTINUOUS ANNEALING LINES – FUTURE-ORIENTED SOLUTIONS FOR DEMANDING PRODUCTS
Advanced annealing lines are essential for ensuring precisely controlled metallurgical properties – as required for high-end steel applications – and fast processing speeds.
Annealing lines from Unisons International feature a flexible, multi-zone furnace able to process a broad range of steel grades and dimensions at very high speeds. Line equipment includes fully automatic coil feeding, mashed lap or laser welders for head to tail strip joining, strip-cleaning, state-of-the-art drives and automation solutions.
METALLIC COATING LINES – ADDING VALUE FOR A WIDE RANGE OF APPLICATIONS
A general trend in today’s steel industry is the increased emphasis placed on adding product value and profit margin for rolled products through the application of special coatings.
A broad range of solutions are offered for metallic coating of both hot-rolled and cold-rolled strip in continuous hot-dip or electrolytic coating lines. This value-added, high-quality material is extensively used in construction, in appliances, in automotive and in packaging applications as a well-proven and time-tested solution for corrosion protection.
ORGANIC COATING LINES – COLORFUL PRODUCTS FOR CORROSION-PROTECTION APPLICATIONS
Unisons offers a full spectrum of solutions for continuous organic coating lines to meet the requirements for a wide range of product applications. As demonstrated by numerous line installations worldwide, the plants are characterized by high throughput rates, operational reliability, production flexibility and provide the basis for outstanding strip-coating quality.
On the basis of decades of experience in the engineering, supply, installation and start-up of organic coating lines, Unisons offers optimized solutions for different coating compositions, coating colors, various steel grades and varying strip dimensions. In addition to imparting an aesthetically pleasing and decorative appearance to the strip, color coatings substantially improve corrosion resistance, especially for outside use. The strictest demands for high-end applications are fully met, such as in the automotive and household appliance industries. Both primary and secondary organic coating layers can be imparted to both strip sides, including the application of polyesters, epoxy, polyurethane, PVDF, acrylic and plastisoles.
CONTINUOUS STAINLESS STEEL LINES – EFFICIENT, RELIABLE AND ECONOMIC
Stainless lines from Unisons combine the traditionally separate processes of rolling, annealing and pickling, skin passing, and leveling in one integrated processing line.
Primetals Technologies’ stainless lines feature integrated rolling and processing, using additional lateral support rolls to ensure stable and controllable rolling, cleaning sections that ensure strip cleanliness prior to the annealing furnace and annealing and pickling sections using a tunnel type furnace and acid pickling.
ELECTROLYTIC CLEANING LINES – COMPACT PROCESSING LINES FOR BIG GAINS IN EFFICENCY
The electrolytic cleaning lines (ECL) supplied by Unisons enable to remove the remaining iron fines and oil residues from the tandem mill.
Advanced ECL technology provides outstanding coils cleanliness before the coils reach the downstream batch annealing furnace to obtain perfect surface cleanliness. This type of line could also be used as coil buildup line. Modules such as payoff reel, shear, welder, cleaning section, etc. are common with galvanizing lines.
STRIP-FINISHING LINES – ADDING THE FINAL TOUCH TO HIGH-QUALITY PRODUCTS
Proven and reliable finishing-line solutions from Primetals Technologies are offered as separate, ready-to-operate machines down to smaller component upgrades.
Unison offers a full range of finishing-line solutions to meet all downstream product requirements. As a lifecycle partner for the metals industry, we work closely with producers to ensure that all production and quality demands are met. Services include investment planning, the preparation of operational concepts and the engineering of plant layouts as the basis for optimized plant performance.
