Abstract: The burden components and smelting practice with high PCI rate under low grade vanadium titano-magnetite at No.1 blast furnace of Ironmaking Plant of Panzhihua Steel and Vanadium Co.,Ltd had been discussed in the paper.For the purpose of increasing PCI rate and decreasing coke rate,some measures like adding pulverized coal combustion supporting agent,double pulverized coal injection guns,increasing the rate of high volatile bituminous coal of pulverized coal,increasing blast temperature and improving the particle size of pulverized coal as well were taken in order to improve the combustion performance of pulverized coal.Furthermore,some other measures,for example,increasing the blast kinetic energy,increasing the theoretical combustion temperature,increasing ore platform width to stabilize gas flow,reducing the temperature fluctuation range of blast furnace,maintaining suitable slagging system,were used at blast furnace to improve the combustion performance of pulverized coal and increase PCI rate.In the burden grade of 49.35% iron in the first quarter of 2014,the PCI rate was 154.29 kg/t,coke rate decreased to 421 kg/t.In the burden grade of 49.32% iron in 2014 April,the PCI rate reached 164.47 kg/t,coke rate decreased to 417 kg/t.
