Practice of Cost Reduction and Efficiency Improvement in Jingang Iron-making Plant
Due to changes in the structure of raw materials and the increase in harmful element loads,Jingang iron-making plant has problems such as poor overall furnace stability and inappropriate pressure.To address these issues,measures will be implemented from September to December 2023,including the integration of pre iron,improvement of fuel evaluation,optimization of raw material and fuel structure,improvement of operating systems,and coal ratio research.These measures have significantly improved furnace stability,increased coke load from 4.6-4.7 t/t to over 4.90 t/t,reduced coke ratio from above 380 kg/t to below 350 kg/t,and increased coal ratio from 150 kg/t to over 170 kg/t,resulting in significant cost reduction and efficiency improvement.
