METHOD OF HOT ROLLING OF STEEL STRIPS FOR ENAMELING

摘要

FIELD: plastic working of metals, namely processes for hot rolling of steel for enameling. ^ SUBSTANCE: method comprises steps of hot rolling of steel containing boron and aluminum in continuous wide strip rolling mill at varying temperature tc for coiling strip and time period T of rolled piece passing from last stand of mill till coilers depending upon its final thickness h while setting tc = 720 - 750°C for h = 2.0 - 2.2 mm and setting tc = 710 -740°C for h = 2.4 -2.8 mm at T < 7S AND AT T > 7 s and h = 3.0 -4.2mm setting tc =700 -730°C. ^ EFFECT: less loss of yield due to enhanced microstructure of steel. ^ 3 ex
