Metal`s e.g. steel, acid pickling detection and control method, comprises measuring molecular hydrogen content in gaseous state released in atmosphere near metal, and taking correction actions when content exceeds overpickling threshold

摘要

#CMT# #/CMT# The method involves measuring molecular hydrogen content in a gaseous state released in the atmosphere near a metal related to standard temperature and pressure conditions. Correction actions are taken when the molecular hydrogen content exceeds overpickling threshold to reduce the overpickling. The hydrogen content is expressed in moles per square meter of a treated metal surface. #CMT#USE : #/CMT# Used for detecting and controlling acid pickling of a metal such as steel, stainless steel or copper, on a continuous production line (claimed) of steel sheets or strips. #CMT#ADVANTAGE : #/CMT# The method efficiently detects and controls the acid pickling of the metals in order to efficiently control overpickling of the metals, thus reducing the risks of overpickling. The method optimizes the use of expensive additives such as over corrosion inhibitors. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a flowchart of a method of detecting and controlling acid pickling of a metal. `(Drawing contains non-English language text)`.
