Title: Method for removing oxide scale from metallic surface
Inventor: FUMA TOYOJI
IPC: C23G5/00
Filed: 1982-09-22
Abstract: PURPOSE:To remove easily oxide scale from a metallic surface without damaging said surface by irradiating the oxide scale deposited on metallic surface with laser light in mixed inert and reducing atmospheres and removing the oxide scale. CONSTITUTION:A metallic plate 2 having thereon with deposited oxide scale 1 is moved in an arrow direction and a gaseous mixture of an inert gas and a reducing gas is ejected through a blowing nozzle 4 from a cylinder 7 onto the surface of the plate 22.

CONSTITUTION:During reaction, for example, a heating medium A becomes a heating medium for heating, and a heating medium B becomes a heating medium for heating. The heating medium for cooling is heated by means of the heating medium B and vaporized to produce gas, which flows through a filter 20 of a partition part 18 and is guided to a reaction part 16 and reacts to a reaction material 6. Heat generated in this case is cooled by means of the heating medium A. Meanwhile, during reversible reaction, the heating medium A becomes a heating medium for heating, and the heating medium B becomes a heating medium for cooling. Reaction gas generated as a result of the reaction material 6 being heated flows through the filter 20 and is guided to a vaporizing and condensing part 17 and cooled by means of the heating medium B for condensation and liquefaction. As noted above, when, during reaction and during reversible reaction and during a stop, reaction gas leaks from a reaction container 14, the reaction gas is not discharged in the open air but in the heating medium.
