Definitions
- the invention relates to a process for pickling a steel part and in particular a strip of stainless steel sheet.
- air blowing has the sole function of stirring the solution because it is well known that in a sulfuric medium the oxidation potential of iron is such that a simple stirring in air does can oxidize iron Fe 2+ to Fe 3+ .
- the object of the invention is to propose a pickling process which ensures, in a very short time, the pickling of a steel part and in particular of a stainless steel strip, the pickling time being compatible with the durations imposed on a production line for the sheet metal part or strip.
- the subject of the invention is a process for pickling a piece of steel and in particular a strip of stainless steel sheet, consisting in applying an aqueous pickling solution consisting of hydrochloric acid and ferric and ferrous pickling ions. in solution, and, in order to maintain a constant pickling power of the aqueous hydrochloric acid solution having a pH of less than 1, to maintain the concentration of Fe 3+ ions at a value of between 1 g / liter and 300 g / liter, by reoxidation by means of oxygenation of the Fe 2+ ions generated during pickling, the REDOX potential being maintained at a value between 0 and 800 mV, potential measured between a platinum electrode and a Ag / AgCl reference electrode placed in the solution.
- the invention also relates to the use of the pickling method according to the invention in the field of accelerated pickling of a steel part and in particular of a stainless steel strip on an on-line production installation, continuously of the strip. in steel.
- pickling baths based on hydrochloric acid are considered to generate corrosion of the surface of the pickled parts, this corrosion being of the pitting type.
- the non-polluting pickling processes preferably use solutions comprising, alone or in combination, in different concentrations, sulfuric and hydrofluoric acids.
- the pickling tests were carried out with a single acid so as to avoid the formation of insoluble complex compounds, the solution being intended to be recycled, that is to say reused in pickling.
- pickling solutions have been tested for pickling efficiency, taking into account their maximum efficiency by adjusting the REDOX potential corresponding to the different acid concentrations used.
- the residence time is adapted to the composition of the steel and to the type of oxide to be etched.
- the REDOX potential is fixed at 460 mV relative to an Ag / AgCl reference electrode, the potential being kept constant by injection of air and additional supply of peroxide. hydrogen.
- Table 1 below presents the different pickling speeds measured in loss of material in grams per square meter and per second for different grades of steel: Steel Solution A Solution B Solution C The invention AISI 304 0.41; 0.37 0.42; 0.37 0.59 0.28; 0.27 0.31; 0.27 0.63-0.56 AISI 316L 0.31 0.40 0.53 AISI 430 0.46 - 0.46 0.92; 0.90 1.6 - 1.1 AISI 430 Ti 0.65 - 0.67 1.01; 0.99 1.5 - 1.8 AISI 409 0.55 - 0.58 0.93; 0.96 1.3 - 1.6
- the surface of the strip stripped with a hydrochloric solution has a white appearance, without pitting, while the surface of the strip stripped with an aqueous sulfuric acid solution has a blackish appearance.
