Push pickling lines
ANDRITZ METALS is a leading supplier of pickling technology for both carbon and stainless steel strip. Our push pickling lines (PPLs) operate economically, are highly flexible, environmentally compliant, and provide high-quality products.
The advantage of the push pickling line (PPL) is its high flexibility combined with high productivity at low investment costs. Cost-intensive equipment like welding machines, loopers, and bridle rolls, are not required. The shallow pickling tank design ensures high turbulence and reduced pickling time.
The push pickling lines were developed and introduced to the industry by ANDRITZ RUTHNER in 1965. Since then, ANDRITZ METALS has built more push pickling lines worldwide than any other supplier.
ANDRITZ METALS push pickling lines are capable of processing strip thicknesses from 0.8 mm up to 16 mm and strip widths from 600 mm up to 2100 mm, with different steel grades and dimensions, coil by coil, and in direct succession. We have supplied lines for carbon steel with a maximum capacity of up to 1,000,000 tons/year. The optimized pickling process, with individual circulation and heating system, ensures minimized consumption of utilities, while the result is always a scale-free strip surface.
With the installation of a new push pickling line for stainless steel, ANDRITZ METALS has broken new ground. Its main features include four shot blast machines, two brush scrub machines, and polypropylene pickling tanks.
Many years of experience in design, manufacture, and commissioning demonstrate our expertise in supplying customized turnkey solutions.
