Practice of Production Increase and Consumption Reduction of 1#5 100 m3 Blast Furnace
The 1#5 100 m3 blast furnace of Shandong Iron and Steel started operation in December 2017,and after the furnace started,it experienced a situation of"low production and high consumption".The blast furnace aims to increase production and reduce consumption.By adopting measures such as optimizing the loading system,improving the activity of the furnace cylinder,and increasing the stability of the molten iron[Si],the two streams of air in the blast furnace are smooth,the furnace shape is regular,and the blast furnace achieves efficient production with increased production and reduced consumption.Since the fourth quarter of 2023,the technical and economic indicators of the 1#5 100 m3 blast furnace have improved significantly.In December 2023,the average blast furnace air volume of 7 750 m3/min has reached the best level in history,and the utilization coefficient has been increased from 1.90 t/(m3·d)to 2.22 t/(m3·d).The coke ratio was decreased to 345 kg/t from 371.5 kg/t in the first half of the year.
