A modified diagram of theoretical requirements of carbon in ore reduction and heat supply for iron smelting has been proposed. The carbon requirements for reduction of Fe_3O_4 and that of wustite under different degrees of direct reduction of wiistite are separately considered in the proposed diagram. It is evident that the heat requirement varies with the degree of direct reduction, and is different from that conventionally adopted by some workers.The proposed diagram indicates the possibility of reducing the...

A modified diagram of theoretical requirements of carbon in ore reduction and heat supply for iron smelting has been proposed. The carbon requirements for reduction of Fe_3O_4 and that of wustite under different degrees of direct reduction of wiistite are separately considered in the proposed diagram. It is evident that the heat requirement varies with the degree of direct reduction, and is different from that conventionally adopted by some workers.The proposed diagram indicates the possibility of reducing the coke ratio to about 450 kg/ton of pig-iron, by proper preparation of raw materials, by working with a moderate driving rate under a favourable distribution of ascending gas currents across the furnace cross section to improve the gas utilization and by lowering the starting temperature of reduction of wustite.In actual practice, a surplus of reducing agents above the equilibrium is required, in order to control a proper rate of reduction; and stronger peripheral and central gas currents are required for smoother operation. Thus, the lowest possible coke ratio and the degree of direct reduction are usually higher than that theoretically required for minimum carbon supply, and can only be attained with easily reducible sinters or pellets.

The benefited high quality burden is the basis for intensifing blast furnaces operation. "The benefited high quality burden" means the burden having following specialities, namely: high-grade, stability, heat-prepared, uniformity, smallness and free from fines. A high iron content of the burden is a necessary term for raising productivity and lowering coke consumption. In order to obtain high-grade sinters and pellets with proper stability in composition, high iron content, lower ferrous oxide content,...

The benefited high quality burden is the basis for intensifing blast furnaces operation. "The benefited high quality burden" means the burden having following specialities, namely: high-grade, stability, heat-prepared, uniformity, smallness and free from fines. A high iron content of the burden is a necessary term for raising productivity and lowering coke consumption. In order to obtain high-grade sinters and pellets with proper stability in composition, high iron content, lower ferrous oxide content, higher strength, close size range and less fines, it is necessary to take efficient measures, such as fine-grinding and having it well beneficiated, improving the mixing and blending of the raw materials, choosing the proper size range of sinters, properly decreasing fuel consumption and making up good proportion of high basicity sinter and low basicity pellet, apart from careful operation and strict control of the agglomeration. Moreover, it is also necessary to have the more powerful agglomerating equipment and automatic control of agglomerating process; these can not only save man power, but also provide reliable means for achieving good quality and high production.

精料是高炉强化的基础.精料的内容可以概括为"高、稳、熟、小、匀、净"六个字.提高含铁品位是增产节焦的前提,也是精料的基础.要获得成分稳定、品位高、氧化亚铁低、强度好、粒度均匀、粉末少的优质烧结矿和球团矿,除了对造块过程本身进行精心的操作和严密的控制外,还必须采取一系列措施:如注意铁矿的细磨深选;加强原料时混匀中和;进行烧结矿的整粒;降低燃料用量以及生产高碱度烧结矿和低碱度球团矿搭配使用等都是行之有效的方法.另一方面,造块设备的大型化和生产过程的自动控制和调节,不仅节省人力而且为产品的优质高产提供了可靠的手段.

In order to study the metallurgical properties of the pellet, experimental smelting with pellet-ratio up to 90% were performed in a 100m~3 blast furnace. Samples were taken from the furnace stack at different levels. Changes of pellet properties, such as reducibility at high temperature, strength after reduction, pulverization, softening, fusion, sticking, etc., in the operation of the furnace were investigated. The metallurgical effect of pellet in the blast furnace operation was studied,...

In order to study the metallurgical properties of the pellet, experimental smelting with pellet-ratio up to 90% were performed in a 100m~3 blast furnace. Samples were taken from the furnace stack at different levels. Changes of pellet properties, such as reducibility at high temperature, strength after reduction, pulverization, softening, fusion, sticking, etc., in the operation of the furnace were investigated. The metallurgical effect of pellet in the blast furnace operation was studied, The result shows that the pellet behaves better than the sinter. When the pellet are used to replace the sinter, the operating indices has been improved remarkably. However, the degree of improvement of the operating indices is not directly proportional to the increase of the pellet-ratio, It declines as the ratio raises. Thus, it is important to increase the high temperature

为了研究球团矿的冶炼性能,在100米~3高炉上进行了配比达90%冶炼试验和炉身取样.一方面考查球团矿在高炉实际冶炼中高温还原性,还原强度,粉化,软化,融熔,粘结等性能变化,另一方面分析了球团矿对高炉冶炼的影响.试验表明,球团矿比烧结矿冶炼性能更好,以球团矿代替烧结矿,冶炼指标显著改善.但随着球团矿配比增加,冶炼指标改善幅度变小.在保证还原性的情况下,改善球团矿的高温强度,提高软化温度是高炉大量使用球团矿的关键.
