From hot annealed strip to stainless applications used in all life areas

Stainless steel products are fascinating. Stainless is the solution for applications with the need of corrosion, heat or chemical resistance.

Considering additional life-cycle-costs and environmental aspects, stainless is the preferred material for household goods, commercial kitchens, sinks, panels, architecture, dishwashers, cutlery and processing equipment.

Annealing and pickling

ANDRITZ world market leadership in stainless steel processing equipment is based on its large offering of advanced annealing and pickling lines for hot-rolled and cold-rolled strip. We have supplied annealing and pickling lines for stainless steel with innovative engineering. Some of these lines have been acclaimed as having a "world record production rate" or the "largest strip dimensions in the world". 

Mixed acid regeneration

ANDRITZ knows the requirements for continuous, stable, and successful operation of stainless steel pickling lines. PYROMARS is the only mixed acid regeneration system that can handle all typical waste acids from stainless steel pickling processes, and it is also easy to operate. Hence, it is second to none as the most advanced and most proven technology worldwide. ANDRITZ newly  developed ZEMAP technology transforms stainless steel mixed acid pickling into a zero-effluent process.

Cold rolling

Thanks to its broad range of cold rolling mills for strip widths from 60 to 2,100 mm, ANDRITZ has been one of the preferred cold rolling technology suppliers for decades. The supply focuses on 2-high, 6-high, S6-high, 20-high rolling mills, and inline/offline skin pass mill stands.

Finishing

With over 300 lines worldwide for slitting, side trimming, cutting to length, and shearing, ANDRITZ is one of the market leaders in this segment. ANDRITZ has the optimum solution for all kinds of materials (high-precision cold-rolled strip, surface-sensitive stainless steel, aluminum, copper strip, or hot-rolled strip). A maximum degree of flexibility is ensured with our large range of patented solutions. Blanking lines are used by car manufacturers and/or their specialized sub-suppliers to cut car body sheets. Depending on the intended application, rectangular, trapezoidal, curved, or other special shapes can be produced with these lines. Major car manufacturers all around the world use ANDRITZ lines.

Stamping

With over 8,000 automatic punching and metal forming presses worldwide, our customers produce high-quality formed and punched products. Our sheet metal forming solutions find applications in the automotive (OEMs and suppliers), white goods, electronics, electromotor lamination, construction, and consumer goods industries. Numerous well-known companies place their trust in our equipment.

Burners

ANDRITZ is a leading supplier of industrial burners, complete heating systems, and combustion equipment with global experience in many thermal process industries. ANDRITZ delivers industrial burners and heating systems for a wide range of thermal applications in industry, particularly in the steel and aluminum industries, the forging industry, and for many other low- and high-temperature processes.

Shape control

ANDRITZ is an experienced rolling mill manufacturer and has built flatness measurement and flatness control systems under licence from the VDEh-Betriebsforschungsinstitut (BFI) for more than 40 years, registered under the shape:tronic system trademark. The general-purpose shape control systems are used in different kinds of rolling mills in the steel, stainless steel, aluminum, and nonferrous metal industries. The latest design of the ANDRITZ Sundwig BFI shapemeter roll has a completely uniform, homogeneous surface, free of any gaps, thus avoiding damage to the strip surface and offering unlimited possibilities in roll coating. The service life of the roll surface is virtually indefinite thanks to the wear-resistant coatings used, for example tungsten carbide.
