Unlike hydrochloric and sulfuric acids,nitric acid is an oxidizing acid,and it is difficult to inhibit high and medium concentrations effectively.Some of the inhibitors used for a nitric acid pickling medium are listed in Table 3.Tables 4 and 5 indicate inhibitors for hydrofluoric acid and phosphoric acid pickling media,respectively.For Pickling Line Modeling for Advanced Process Monitoringexhaust acid solution from the pickling line to near-constant levels.The increasing demand for high quality steel products requires that the correct degree of descaling is maintained by process Pickling Samuel Steel Pickling GroupOur Patented ProcessesValue-Added ServicesSpecificationsHydroSurge Our hydrochloric acid pickling process,uses high velocity acid injection to attack scale.This configuration increases our pickling efficiency and ensures a cleaner pickled surface.CoilBrite Our sprayless rinse systems are designed to remove all acid residue without line stop staining.See more on samuelSupplier Of Industrial Electric Control System T-controlWuxi T-Control Industrial Technology Co.Ltd.is an enterprise integrating the design,production,installation and commissioning of non-standard equipment,mainly including fully automatic wire rod pickling lines ( straight / tunnel / U type) and various non-standard power distribution cabinets and control cabinets.
Feb 02,2015·After oil,grease,and other organic contaminants are removed from the surface of steel in a degreasing tank,there still remains a thin layer of iron oxide (mill scale) adhered to the steel.In a galvanizing plant,steel will be pickled in an acid tank after the degreasing operation and before pre-fluxing.Acid pickling removes the iron oxides or scales from the steels surface to expose a bare area and permit a galvanized coating to form upon immersion in a molten zinc bath.Pickling and Passivating Stainless Steelacid pickling.Patchy,uneven pickled surfaces can result if surfaces are not clean before the acid treatment.2.3 Passivation Passivation usually occurs naturally on the surfaces of stainless steels,but it may sometimes be necessary to assist the process with oxidising acid treatments.Unlike pickling,Pickling lines SMS groupEconomic and ecological pickling lines.SMS group delivers pickling lines from a single source as a system supplier.The lines are outstanding for their high pickling performance as well as low maintenance and operating costs over a long service life.
