萍钢炼铁把测算的吨铁总成本作为评价铁矿性价比好坏的指标,且吨铁总成本是指吨铁原燃料成本、吨铁加工成本、锌危害、脱硫成本、规模成本、焦粉差价、返矿差价与炼钢脱磷成本之和。正确测算出铁矿性价比的主要目的,在于指导炼铁配矿和采购工作,并可对性价比差的铁矿提供降价的理论依据。提出了降低炼铁用矿成本有效途径,一是正确测算铁矿性价比,二是对性价比差的铁矿进行合理降价,三是多使用性价比高的铁矿,四是科学配加缺陷矿(优化炼铁用矿结构)。
Pinggang Iron & Steel calculates the total tonnage of iron and iron as an indicator of cost performance, and the total tonnage of iron is the cost of raw materials tonnage iron, iron and iron processing costs, zinc hazards, desulfurization costs, scale costs, coke powder Difference, return difference and the cost of steel dephosphorization. Correctly calculate the main purpose of iron ore cost performance is to guide the iron ore with ore procurement and procurement, and can provide cost-effective iron ore to reduce the price of the theoretical basis. Proposed an effective way to reduce iron ore mining costs, one is to correctly calculate the iron ore price, the second is to cost-effective iron ore reasonable price cuts, the third is to use more cost-effective iron ore, the fourth is scientifically equipped with defect ore (optimization Ironmaking mine structure).
