MULTI-PURPOSE PROCESSING LINE FOR THERMAL TREATMENT AND COATING APPLICATION AS A RESULT OF IMMERSION INTO STEEL STRIP MELT Russian patent published in 2019 - IPC C21D9/573 C23C2/02 

FIELD: metallurgy.

SUBSTANCE: process line of multi-purpose continuous processing, which is capable of providing heat treatment and coating application as a result of dipping into a melt for a steel strip, which includes: annealing section (1) for heating the steel strip to a predetermined annealing temperature and for holding the steel strip at said annealing temperature, first displacement section (2), overaging section (3), capable of maintaining steel strip temperature in range from 300 °C to 700 °C, second movement section (4) capable of adjusting temperature of the steel strip to enable coating application as a result of immersion into the melt for the strip, and a coating application section as a result of immersion into melt (5), where the first displacement section (2) includes in cooling means (21) and heating (22) sequence.

EFFECT: providing thermal treatment and coating application as a result of immersion in molten steel strip.
