| Abstract: | Technologies of high efficient slab caster and its application effect at PISCO(Panzhihua Iron & Steel Co.) were presented.The casting speed was increased to the range between 1.30 m/min and 1.80 m/min owing to developing reasonable mold flux,primary cooling scheme and molten steel temperature control.The rate of sliver defect on cold-rolled sheet was decreased from 10.97% to 1% due to adjusting compositions and performance of steel slag,optimizing refining process,and designing high viscosity flux.Meanwhile... |
| Keywords: | slab continuous casting high efficient continuous casting mold flux primary cooling slab quality |
