The improvements on 360 m 2 sintering machine have been made since it started operation in 2009 at Pan- zhihua vanadium iron works. The equipment in good condition assured the operating rate of sintering machine. Process improvement enhanced the utilization coefficient and sinter quality，the utilization coefficient of sintering reached 1.415 t/（m 2 ·h）， the operating rate 96.52%， the drum strength 73.27% and solid fuel consumption 45.27 kg/t in 2010. The utilization coefficient of sintering was 1.425 t/（m 2 ·h）， the operating rate 97.39%， the drum strength 73.61% and solid fuel consumption 47.96 kg/t on January to June 2011.
