Improvement of Properties of Heavy Plates by Secondary Steelmaking Technologies and Rolling Conditions
Abstract
In order to obtain the mechanical and technological characteristics required
for controlled rolled plates it is necessary to realize a very low content of sulphur
by desulphurized mixtures using CaO-Al2O3-CaF2 and injection of powdered SiCa
or core wire SiCa. This paper presents the influence of rolling conditions on
mechanical properties, the influence of the rolling schedule and the temperature
range of the end rolling of the microstructure.
