The permeation is commonly studied using external polarisation to produce the hydrogen, but we used the pickling acid as the hydrogen source.
Introduction of iron into the pickling acid has only a minor effect on the current versus time curve (Figure 7).
Business area Sandvik Materials Technology is participating as a pilot for the development of technology for the separation of metals from pickling acid
and purification of rinsing water.
recovery plant) for pickling acid
used in pickling hot-rolled steel at Rautaruukki's Raahe Mills.
Plant operators eliminated the hazards and expense of disposing of spent pickling acid
by recycling it on the premises.
Tenders are invited for Design, Engineering, Supply, Erection, Commissioning, Testing, Demonstration Of Pg Parameters, Operation, Supervision And Training Of Acid Pump For Pickling Acid
Heating System At Pl#2 At Bokaro Steel Plant (Bsl), Sail, Bokaro
Elimination of the need to clean the titanium chips (no use of soaps, detergents and pickling acids
) or the machined components, as liquid nitrogen just evaporates into the air without polluting;
