Reinforcement of the production capacity at Wakayama No.5 Sintering Plant
Reinforcement construction of Wakayama No.5 sintering plant performed from August 2006 to January 2009 to adapt expansion of blast furnaces.A new strand,which grate area is 185m2,was built adjacent to an existing strand (122m2) while the existing one had been operating continuously during construction.A packed bed type circular cooler was installed for the new strand to decrease energy consumption.In order to improve the granulation,a new separate granulation system using a pan pelletizer which diameter is 7.5m was installed.Moreover,exhaust gas treatment system was installed.In addition,existing raw materials bins and coke breeze bin were appropriated to decrease construction cost.These facilities are shared with both strands.As a result,increase of permeability of the sintering bed has achieved by using the separate granulation system while the finer average size of the raw materials can be used.Furthermore,the thickness of the sintering bed can increase and return fine ratio decrease so that the productivity increases.The concentrations of SOx,NOx,and dioxins are also kept low enough to attain an environment standard.The commercial operation of Wakayama No.5 sintering plant begins in January 2009 and has been continuing the favorable operation about 36t/d/m2.
