DEVICE FOR THERMAL TREATMENT OF HOT-ROLLED SHEET

摘要

FIELD: metallurgy. ^ SUBSTANCE: installation contains top and bottom fissural collectors, installed behind them top and bottom rollers with adjusting clearance for placement in it of hot-rolled sheet and collectors with injectors, located in top and bottom interroller space, additionally collectors with injectors are implemented as multichamber, and output cross-sections of injectors of one chamber of each collector differs from output cross-sections of injectors of other chamber of the same collector. ^ EFFECT: obtaining hot-rolled sheet with specified level of mechanical properties and structure in wide grade and thickness range. ^ 2 dwg
