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,the mean operating rate of slab caster was increased from 89.39% to 92.96% benefit from reasonable distributing function between two slab casters,applying quick exchanging for nozzle,reducing reheating time of molten steel at LF,and improving production capacity of RH.These achievements have provided important technology supports for PISCO to obtain 154 million tons product of continuously cast slab in half a year of 2008.
