Annealing and Pickling Line (APL) for Stainless Steel annealing and pickling coil

Pickling operations are very important in the manufacture of stainless steel and provide the transition between hot plant and cold plant, after the annealing operations. It involves multi-step chemical reactions, and is one of the most polluting and costly chemical processes in the steel industry due to the presence of the highly corrosive annealing and pickling coilAnnealing of Cold Rolled Steel IspatGuruFig 2 Typical schematic diagram of a continuous annealing line. Steel strip coil which to be annealed is placed at the decoiler. Since the process is continuous, head end of the new coil is joined with the tail end of the previous coil. During the period when strip joining is taking place, the continuous movement of the strip in the heat annealing and pickling coil

Continuous aluminum annealing and pickling line

Customized annealing and pickling lines for aluminum - as individual process lines or combination lines - especially for automotive and aerospace strip ANDRITZ provides customized and full integrated annealing and processing lines, combining heat treatment and surface treatment process or as individual process lines, especially for automotive and aerospace strip.Cutting Edge Processing Lines Primetals TechnologiesAdvanced 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.Downstream Processing - EPS - Eco Pickled SurfaceProcesses like galvanizing, coil coating and cold rolling perform better with EPS-pickled steel. EPS mitigates surface defects like silicon streaks, minor roll marks and pitting. Certain cleaning steps can be eliminated by virtue of the clean, oil-free EPS surface.

THE FUTURE IS BRIGHT ANNEALING annealing and pickling coil As the only BA mill in China with our own pickling line, we have the unique advantage of being able to handle our own pickling process from black coils, allowing us to closely monitor the quality process starting from the initial stage of raw material. This permanent stock of black coils also allows us to annealing and pickling coilHot Rolled Pickled & Oiled Steel Sheet & Coil - Metal annealing and pickling coilAdvantages of Hot Rolled Pickled & Oiled (HRPO) Steel Sheet & Coil There are a number of advantages to a pickled product such as hot rolled pickled & oiled (HRPO) steel sheet & coil. First, when a material is pickled, it no longer has the scale on its surface, making it much easier for a laser or any cutting apparatus to profile an exact part.Hot annealing and pickling lines - Fives in SteelHot annealing and pickling lines In cold rolling workshops for stainless steel production, the hot annealing and pickling line (HAPL) is the first continuous process used to heat treat and pickle the hot rolled coils to obtain so called white coils (also called 1). Depending on the grades, in-line heat treatment can be applicable or not.

Pickling solutions. For carbon (C) steel, sulphuric (H2SO4) acid is used in most batch pickling operations, whereas hydrochloric (HCl) acid has become the pickling agent of choice, as of 1994, for continuous operations with hot rolled strip.
