Abstract: The multi-cylinder dryer of a paperma-chine comprises a first tier of cylinders, wherein a web (W) travels supported by a first dryer wire (k1) on the cylinders (1) of the tier of cylinders, as well as a second tier of cylinders, wherein the web (W) travels supported by a second dryer wire (k2) on the cylinders (2) of the tier of cylin-ders.  Upon passing around its wire guide roll (h1;h2), each dryer wire (k1,k2) forms a loop having at least one section (c - d), along which said wire (k1;k2) is free from the run of the web (W) and which in the wire traveling direction is immediately upstream of a point (d), at which the wire is received on the guide roll (h1;h2). Along a wire section (a - d) between a cylinder (1; 2) and the guide roll, a nozzle (s2) inside the wire loop is used blowing air through said free section (c - d) of dryer wire (k1; k2) into a pocket (t2,1; t1,2) between it and a cylinder (2;1) of the opposite tier of cylinders for venti-lating said pocket through a plenum zone (p1+, n+) formed between an air guiding surface (op) located inside the wire loop downstream of the nozzle (s2) in the wire traveling direction, and said free section (c - d).

Abstract: A process for removing scale from stainless steel using an aqueous solution containing hydrogen peroxide and an inorganic acid, i.e., hydrochloric or sulfuric acid. A hot rolled or annealed stainless steel strip (10) covered with scale is immersed into hot inorganic acid contained within pickling tanks (12) and (14). Thereafter, the strip may have residual amounts of tightly adherent scale (11). This scale is activated by a solution containing the inorganic acid and hydrogen peroxide applied to the strip such as by a spray header (16) extending completely transversely across and positioned above the strip and another spray header (18) extending completely transversely across and positioned below the strip. It may be desirable to pass the activated strip through the hot inorganic acid again and reactivate the strip at very high line speeds to insure complete removal of scale from the strip. Any hydrogen peroxide spray dripping from the strip is collected on a catch pan (30) and flowed into a tank (28). Preferably, the collected spent aqueous solution containing the inorganic acid and spent hydrogen peroxide is disposed in the pickling tanks. The aqueous solution aids in the removal of any residual scale and smut remaining on the strip thereby improving the cleanliness of the pickled strip.
