SUMMARY:Expansion of PCI plant at ternium brazil
DESCRIPTION:This work aims to show the industrial development carried out to expand the PCI plant capacity of Ternium’s blast furnaces in Rio de Janeiro-Brazil. Ternium has got two blast furnaces with a daily production of 7500 thm each. The PCI plant's original design features have got two 60 t/h pulverized coal mills with two injection stations with dual vessels allowing average PCRs of up to a maximum of 180 kg/thm for each blast furnace.

Over the years, the PCI plant has presented capacity and availability problems regarding the coal injection and grinding stations, affecting the plant's hot metal production and leading to losses due to the lack of coal and consequent instability in the operation of the blast furnaces.

The PCI expansion improved the injection stations with the addition of a third injection vessel, a new coal silo of 800 tons and a third coal grinding mill and drying plant with the same type and grinding capacity and with alternative pneumatic transport increasing the versatility of the plant in general. In addition, dual coal lances were implemented with dynamic distributor and closed loops control allowing uniform distribution of coal between lances and higher PCR up to 220 kg/thm.
