FIELD: performing operations.
SUBSTANCE: group of inventions relates to cleaning of strip steel surface, and more specifically to method of annealing and etching of cold-rolled stainless strip steel and equipment for annealing and etching of cold-rolled stainless steel strip.
EFFECT: creation of efficient process of annealing and etching of cold-rolled stainless steel strip, in which etching efficiency is increased due to possibility of regulation of oxidation-reduction characteristics of etching solution in baths of cascade overflow system of continuous etching.
