ABSTRACT The Si content in pig iron is one of the important indicators for evaluating the technical level of ironmaking in the blast furnace. From the late twentieth century, the production of low-Si pig iron has attracted more and more attention in steel industries of the world. For ironmaking process, the decrease of Si content is beneficial for increasing the coefficient of utilization of the capacity of blast furnace, reducing the fuel consumption and increasing the output. For the following steelmaking process, the decrease of Si content is beneficial for reducing the amount of slag, consumption of flux and shortening steelmaking time. Overall, it is an important technology for productivity enhancement and energy saving. In this paper, the transfer mechanism and influence factors of Si in blast furnace have been reviewed and discussed in detail. This paper will provide theoretical basis and operation strategies for reducing the Si content.

高炉硅转移机理及影响因素综述

摘要 生铁中Si含量是评价高炉炼铁技术水平的重要指标之一。从二十世纪后期开始，低硅生铁的生产越来越受到世界钢铁工业的重视。对于炼铁过程，降低Si含量有利于提高高炉产能利用率，降低燃料消耗，提高产量。对于后续炼钢过程，Si含量的降低有利于减少渣量、熔剂消耗和缩短炼钢时间。总的来说，它是提高生产力和节能的一项重要技术。在本文中，对Si在高炉中的转移机理和影响因素进行了详细的综述和讨论。本文将为降低Si含量提供理论依据和操作策略。
