STEEL SHEET PROCESSING UNIVERSAL LINE FOR PRODUCTION OF VARIOUS HIGH-STRENGTH STEELS Russian patent published in 2014 - IPC C23C2/06 C21D9/52 

FIELD: process engineering.

SUBSTANCE: invention relates to metal forming. Proposed line comprises unwinding and flushing station, heating station, holding station and delayed cooling station. Hydrogen cooling station and water quenching station are located downstream thereof and in parallel therewith. Note here that downstream of hydrogen cooling station located are reheating station, overageing station, final cooling station, straightening station, finishing station, lubrication station and winding station. Downstream of water quenching station located are acid flushing station and galvanic station. Note also that hot zinc-plating station is arranged downstream of reheating station and connected therewith. Note also that galvanil-plating station is arranged downstream of hot zinc-plating station and connected therewith. Mind that acid flushing station and galvanic stations are separately connected with reheating station via connection channels. Said galvanic station is directly connected via connection channel with unwinding station and flushing station. Water quenching station is connected with delayed cooling station via fixed bypass channel. Reheating station is connected with overageing station via plug-in bypass channel.

EFFECT: integrated functions.
