摘要

本文采用了两种含镍铬复合包袱，包括 SP1（79% 含镍烧结矿和 21% 含铬氧化物球团）和 SP2（84% 含镍烧结矿和 16% 含铬预还原球团），以更高效地制备高镍铬铁。根据冶金性能表征、热力学分析和冶炼参数优化，利用含镍铬复合烧结矿制备出了合格的高铬镍铁。铁、铬和镍的回收率分别超过 95%、90% 和 98%，品位分别为 85.56-85.88%、7.82-8.02% 和 1.59-1.62%。与 SP1 相比，SP2 的冶炼时间较短，这表明适当配比含铬预还原球团有利于冶炼过程。由（Fe，Cr）3C 和（Fe，Cr）7C3 组成的高铬镍铁可用作 200 或 300 系列不锈钢传统原材料的低成本替代品。

Effective utilization of Ni-Cr bearing composite burdens for high-Cr ferronickel preparation

In this paper, two types of Ni-Cr bearing composite burdens including SP1 (79% Ni-bearing sinter and 21% Cr-bearing oxide pellets) and SP2 (84% Ni-bearing sinter and 16% Cr-bearing pre-reduced pellets) were used for the more efficient preparation of high-Cr ferronickel. Based on the metallurgical performance characterization, thermodynamic analysis and smelting parameters optimization, the qualified high-Cr ferronickel were prepared by the utilization of the Ni-Cr bearing composite burdens. The recovery rates of iron, chromium and nickel exceed 95%, 90% and 98% whereas their grades are 85.56–85.88%, 7.82–8.02% and 1.59–1.62%, respectively. Compared with SP1, SP2 possesses lower smelting duration, which indicates the appropriate proportioning of Cr-bearing pre-reduced pellets is beneficial for the smelting process. The obtained high-Cr ferronickel consisting of (Fe, Cr)₃C and (Fe, Cr)₇C₃ can be used as a low-cost substitute for the conventional raw materials of 200 or 300 series of stainless steel.

期刊介绍： Powder Technology is an International Journal on the Science and Technology of Wet and Dry Particulate Systems. Powder Technology publishes papers on all aspects of the formation of particles and their characterisation and on the study of systems containing particulate solids. No limitation is imposed on the size of the particles, which may range from nanometre scale, as in pigments or aerosols, to that of mined or quarried materials. The following list of topics is not intended to be comprehensive, but rather to indicate typical subjects which fall within the scope of the journal's interests: Formation and synthesis of particles by precipitation and other methods. Modification of particles by agglomeration, coating, comminution and attrition. Characterisation of the size, shape, surface area, pore structure and strength of particles and agglomerates (including the origins and effects of inter particle forces). Packing, failure, flow and permeability of assemblies of particles. Particle-particle interactions and suspension rheology. Handling and processing operations such as slurry flow, fluidization, pneumatic conveying. Interactions between particles and their environment, including delivery of particulate products to the body. Applications of particle technology in production of pharmaceuticals, chemicals, foods, pigments, structural, and functional materials and in environmental and energy related matters. For materials-oriented contributions we are looking for articles revealing the effect of particle/powder characteristics (size, morphology and composition, in that order) on material performance or functionality and, ideally, comparison to any industrial standard.
