ANNEALED STEEL TYPES PRODUCTION DEVICE AND METHOD OF SAID STEEL TYPES PRODUCTION Russian patent published in 2017 - IPC C21D9/60 

FIELD: technological processes.

SUBSTANCE: invention relates to annealed steel strip production device and methods of its production. Annealed steel strip production device contains heating zone, including heating section, including first heating plant or induction furnace for heating from 400 to 600 °C and second heating plant for steel strip additional heating from 500 °C up to 1,000 °C, holding section to 120 s inclusive, cooling section, including slow cooling zone from annealing temperature to fast cooling beginning temperature, fast cooling zone is intended for from fast cooling beginning temperature to cooling ending temperature, approximately to 300 °C, third cooling zone from second cooling stopping temperature to temperature between ambient air temperature and 100 °C, optional repeated heating zone, optional annealing zone for local thermal treatment of one or more areas of surfaces in annealed strip longitudinal direction to obtain specified properties in longitudinal direction on annealed strip surfaces one or more sections, annealed strip final cooling zone, area of coating application on annealed strip surface, including, at least, section of electrolytic coating application on annealed strip surface, and winding device for annealed strip winding.

EFFECT: technical result consists in creation of device, ensuring small-scale products production in form of steel strip from AHSS and UHSS type steels and said steel strip local heat treatment.
