In order to effectively break through the bottleneck problem of capacity of sinter, upgrading and transformation of existing 265 m2 sintering machine are implemented. The capacity of sintering machine is significantly enhanced through adopting a series of measures including widening trolley, upgrading main exhauster and optimizing pelletizing system. After the transformation, average daily output of sinter is increased by 1 013 t and utilization coefficient of sintering machine is improved from 1.332 t/ (m2·h) to 1.484 t/ (m2·h); drum index of sinter is increased by 0.3 percentage point and its size composition is improved; solid fuel consumption of sintering is decreased by 1.19 kg/t and electricity consumption is decreased by 4.97 kWh/t so that the energy medium and manufacturing costs are significantly reduced.
