Application of Optimizing Batching Structure in Sintering Machine of Jiusteel
Jiusteel geographical location,traffic conditions,sales radius and so on compared with most steel enterprises in a disadvantage,cost-effective use of its own resources,become the most direct and effective way to improve profitability,but affected by the service life of Jingtieshan mine,the output of self-made comprehensive iron ore concentrate can not meet the demand for sintering materials,especially after the 7#blast furnace of the headquarters is put into operation in July 2020,The proportion of comprehensive purchased concentrate in the sintering process is maintained at 12%～13%,and the cost of molten iron continues to rise due to the impact of high-priced iron resources,and the cost transmission seriously af-fects the profit per ton of steel,and because the composition of various iron materials is very different,and the impact of each component on the cost and product quality is also different,which affects the cost and quality stability control of mol-ten iron,it is necessary to carry out economic evaluation of various iron materials,and actively digest low-cost backlog re-sources,while ensuring stable quality,reduce costs as much as possible,so as to alleviate the current production and oper-ation conditions.
