Abstract
Un proceso para eliminar incrustaciones del acero inoxidable empleando una solución acuosa que contiene peróxido de hidrógeno y un acido inorgánico, esdecir ácido clorhídrico o sulfúrico. Una tira de acero inoxidable laminado en caliente orecodid o cubierta con incrustaciones es sumergida en ácidoinorgánico caliente contenido dentro de tanques de limpieza química de metales. Posteriormente la tira puede tener cantidades residuales de incrustacionesfirmemente adheridas. Estasincrustaciones so n activadas por una solución que contiene el ácido inorgánico y peróxido de hidrógeno aplicada a la tira, porejemplo por un cabezal de rociado que se extiende completamente en dirección transversal y está colocado por encimade la tira y otro ca bezal de rociado quese extiende completamente a lo ancho y está colocado debajo de la tira. Puede ser aconsejable pasar la tira activada a través del ácido inorgánico una vezmás y reactivar la tira a velocidades de línea muyelevadas para garantiza r la remocion completa de las incrustaciones de la tira. El peróxido de hidrógenoque pueda escurrirse de la tira es recogido en una bandeja recolectora y enviada hacia un tanque. De preferencia, la solución acuosaagotada recogida,que contien e el ácido inorgánica y el peróxido de hidrógeno usado, es descartado en los tanques de bano químico. La solución acuosa contribuye a laeliminación de cualquier incrustación residual y suciedad que haya quedadoen la tira, mejorando así l a limpieza de la tira danada.A process for removing scale from stainless steel using an aqueous solution containing hydrogen peroxide and an inorganic acid, ie hydrochloric or sulfuric acid. A strip of hot rolled orecodid or encrusted stainless steel is immersed in hot inorganic acid contained within chemical metal cleaning tanks. Subsequently the strip may have residual amounts of firmly adhered scale. These fouling are activated by a solution containing inorganic acid and hydrogen peroxide applied to the strip, for example by a spray head that extends fully in the transverse direction and is positioned above the strip and another spray head that extends fully. across the width and is positioned under the strip. It may be advisable to run the activated strip through the inorganic acid one more time and reactivate the strip at very high line speeds to ensure complete removal of scale from the strip. Hydrogen peroxide that may run off the strip is collected in a collection tray and sent to a tank. Preferably, the collected spent aqueous solution, containing the inorganic acid and the used hydrogen peroxide, is discarded in the chemical bath tanks. The aqueous solution contributes to the removal of any residual scale and dirt remaining on the strip, thus improving the cleaning of the damaged strip.
