摘要： In a ferrocoke manufacturing method by shaping and carbonizing a mixture of coal and iron ore, a hardly softening coal having a button index (CSN) of not more than 2.0 is used as the coal. The coal can be a blend of hardly softening coal and easily softening coal, and the hardly softening coal can be a coal having a button index (CSN) of 1.0 and a volatile matter of not less than 17%, and the easily softening coal can be a coal satisfying that a value obtained by multiplying CSN of easily softening coal by a blending ratio of easily softening coal in all coals is a range of 0.3-5.2. The coal can also be a blend of hardly softening coal and easily softening coal, and the hardly softening coal can be a coal having a button index (CSN) of 1.5-2.0, and the easily softening coal can be a coal satisfying that a value obtained by multiplying CSN of easily softening coal by a blending ratio of easily softening coal in all coals is nit more than 5.0.

摘要： The present disclosure is generally directed to biopolymers having coiled nanostructures, methods of making those biopolymers, and applications involving those biopolymers. Biopolymers having coiled nanostructures may be produced through a biophysical process by which the shape of a biopolymer macromolecular chain is altered. Biopolymers having coiled nanostructures may then be cross-linked to prepare biopolymeric networks. The biopolymeric networks may be configured to incorporate solid particles, in which they serve to hold the solid particles together against external stresses, solvents, and the like. For this reason, the biopolymers having coned nanostructures are useful in a variety of applications, including in an improved process for forming iron ore pellets.

摘要： An improved process for preparing compacts of finely divided fluorspar for metallurgical use is provided in which water, hydrated lime and molasses are added in specified ratios to fluorspar in a heated mixing vessel. The water facilitates the formation of a lime-molasses coating on the fluorspar particles and impedes reaction of the lime and molasses. The water also provides evaporative cooling of the mixture, subsequent to the mixing operation, causing the molasses to become much more viscous and, resultingly, the mixture to be much less tacky so that it can be efficiently compacted immediately. Following compaction in a compacting machine the compacts are heated in an oven to force the lime and molasses reaction to completion providing a water insoluble binder for the fluorspar particles.
摘要翻译：提供了一种用于制备用于冶金用途的细碎氟石的压块的改进方法，其中水，熟石灰和糖蜜以特定比例以加热混合容器中的氟石加入。水有助于在萤石颗粒上形成石灰糖蜜涂层，并阻止石灰和糖蜜的反应。在混合操作之后，水还提供了混合物的蒸发冷却，使得糖蜜变得更加粘稠，因此混合物的粘性要小得多，从而可以立即有效地压实。在压实机中压实之后，压块在烘箱中加热以迫使石灰和糖蜜反应完成，为萤石颗粒提供水不溶性粘合剂。

摘要： Green (nonfired) pellets of iron ore are prepared by pelletizing the iron ore and 2 to 8 percent by weight of finely divided metallic iron with a particle size below 45 microns in the presence of an aqueous solution, suspension or dispersion of an organic binder, preferably a carbonhydrate. Surprisingly, the low-temperature binder, i.e. the starch, dextrine or the like, in combination with the metallic iron powder, affords considerable structural integrity to the pellets during the initial and subsequent stages of the direct reduction in a shaft-type or rotary furnace.

摘要： The invention relates to an organic ore pelletizing aid, to a method for making it, and to a method for pelletizing ore using the pelletizing aid. The pelletizing aid comprises coal which has been treated with an alkali metal hydroxide. A particular advantage is the provision of good ore ''''ballability,'''' even at relatively high moisture content. The pelletizing aid may be coated with a high molecular weight, water dispersible organic polymer to further improve its performance.
