FIELD: metallurgy.
SUBSTANCE: installation consists of working bath made out of stainless steel with unit of anode protection including electric circuit, auxiliary electrode as cathode, while case of bath operates as anode. Metal pipeline for working solution alternate heating and cooling is welded or soldered on external vertical surface of the bath. A heat screen out of thin-sheet polished metal with applied layer of heat insulation is attached to the pipeline. Also, shut-off T-valves are arranged on end sections of the pipeline. An upper of the valves supplies cooling water and evacuates condensate, while a lower one is designed for supply of steam and drainage of cooling water.
EFFECT: reduced heat inertia of system due to high accuracy maintenance of working solution temperature; usage of same pipeline for heating and cooling bath with working solution; reduced working areas.
