    • A process for preparing blast furnace cokes which contain large amounts of low-grade coal which comprises the steps of adding a binder to a coal for making briquettes which comprises a substantially low-grade coal such as non- and/or poorly-coking coal; either alone or when blended in an amount of up to about 40% or more with a charging coal; mixing the binder and the coal briquetting the mixture in a roll press to form briquettes of two or more types; blending the resulting briquettes of different types with a charging coal in a total amount of about 35% or more of the briquettes based on the charging coal and, to prepare a blended charging coal; and carbonizing the blended charging coal in a coke oven.
    • 一种制备含有大量低级煤的高炉焦炭的方法,包括以下步骤:将煤粘合剂加入到制造压块的煤中,所述煤块包括基本上低等级的煤,例如非焦煤和/或不良焦煤; 单独使用时,或者用充电煤混合量高达约40%以上时, 将粘合剂和煤混合,将混合物在辊压机中压块以形成两种或更多种类型的团块; 将所得到的不同类型的块状物与基于装料煤的总计为约35%或更多的煤的装料煤混合,制备混合的装料煤; 并在焦炉中将混合的带电煤碳化。

    • The strength and density of a metallurgical coke produced in a slot coke oven are both increased by replacing at least a part of the normal loose charge in the oven with compacted materials and fragments thereof made from a mixture of particularly sized particulate fusible bituminous coal particles, non-fusible particles of a material compatible with the burden of a blast furnace, and water. During compacting the pressure and the moisture content of the mix are such that at least some water is squeezed out of the mix. The non-fusible materials that are useful include non-coking coals, poorly coking coals, other carbonaceous materials, such as coke breeze, char, anthracite, lignite, and iron oxide-bearing materials, such as iron ores and waste materials from steel plants. At least a major proportion of the fusible particles and at least a substantial proportion of the non-fusible particles are smaller than about 0.15 mm. The proportion of fusible to non-fusible particles used is such that such mixture of compacted materials and fragments made from such compacted materials that is charged to the slot coke oven becomes transiently plastic, shrinks and forms a single mass of coke when heated to a coking temperature in the oven, which coke mass is readily dischargeable from such oven.
    • 在槽式焦炉中生产的冶金焦的强度和密度都通过用由特别尺寸的颗粒状可熔烟煤颗粒的混合物制成的压实材料和碎片替换炉中的正常松散电荷的至少一部分而增加, 与高炉的负担相容的材料的非易熔颗粒和水。 在压实期间,混合物的压力和水分含量使得至少一些水从混合物中挤出。 有用的非易熔材料包括非炼焦煤,不良焦化煤,其他含碳材料,如焦炭,焦炭,无烟煤,褐煤和含铁氧化物的材料,如钢铁厂的铁矿石和废料 。 至少大部分的可熔颗粒和至少大部分的非易熔颗粒小于约0.15mm。 可熔性与不熔融颗粒的比例使得这种由压缩材料制成的压实材料和片段的混合物被装入槽式焦炉中变成瞬时塑性,在加热到焦化时收缩并形成单一焦炭 烘箱中的温度,该焦炭质量容易从这种烤箱排出。
