浅谈筛分问题对炼铁成本的影响

Brief Talk on Influence of Screening Issue on Iron-making Cost

受长期粗放的管理理念影响,对槽下筛分重视不足,造成不少合格粒度的可入炉料成为筛下物,进入返矿,导致入炉矿成本升高,对炼铁成本影响较大。针对槽下矿石筛分跑粗率对炼铁成本的影响进行了详细的测算和分析,并就相关问题对炼铁成本的影响进行了探讨,说明了细化筛分管理对降低成本的重要作用。

Under the influence of extensive management concept, pre-charging screening was not paid enough attention, which caused a number of chargeable burden with qualified size to become the undersize and returns. This raised burden ore cost and greatly affected iron-making cost. The paper calculates and analyzes in detail the impact of ore pre-charging influence of relevant factors on smelting cost and to cost reduction. screening coarsening rate on smelting cost, discusses the illustrates the importance of detailed screening management
