【摘要】 在建立选矿、烧结(球团)、炼铁等有关数学模型的基础上,研发了可进行地质一采矿一选矿一烧结(球团)一炼铁整体效益测算的专用软件。该软件用模糊综合评判法进行以系统利税总和及生铁产量为目标的多目标决策。结论是提高精矿品位有利于提高矿山-炼铁的整体效益,当有一定限度。当原料和生铁价格变化时,用该软件可实时确定综合效益最佳的精矿品位。更多还原

【Abstract】 Based on the mathematical models of mineral processing, sintering (pellet) ,iron making,the exclusive software is developed, which can evaluated the whole benefit including geology, mining, mineral processing, sintering ( pellet) and iron making. Using fuzzy integrated evaluation method, it makes multi - object - decision by the target of system added profit and pig iron product. The result shows that to raise iron concentrate grade is good for the integrated benefit from mines to iron making,but it should be limited. When the raw materials and the pig iron price change, the software can give the iron concentrate grade of the best integrated benefit immediately.更多还原
