摘要

摘要收集了一座含钒钛磁铁矿（VTM）冶炼高炉（BF）炼铁厂和一座钒回收碱性氧气炉（BOF）车间1年的生产数据。从高炉操作中的还原钒和转炉操作中的氧化钒的角度分析了相应的热力学。利用多相平衡（MPE）软件进行了热力学计算，将广义中心原子模型引入到熔渣的描述中，并应用于熔渣数据库中。分析了操作条件对炉渣和热金属/半钢之间V分布比的影响，并与工厂数据进行了比较。模拟结果可以再现V分布比随炉渣温度和成分的变化，为操作人员控制V分布行为以更好地进行工艺操作提供指导。

Thermodynamic analysis of vanadium distribution behavior in blast furnaces and basic oxygen furnaces

Abstract Production data from a vanadium (V)-containing titaniferous magnetite (VTM) smelting blast furnace (BF) ironmaking plant and a V-recovering basic oxygen furnace (BOF) shop were collected over a period of 1 year. The corresponding thermodynamics was analyzed in terms of V reduction in the BF operation and V oxidation in the BOF operation. The thermodynamic calculations were performed using the software Multi-Phase Equilibrium (MPE), in which generalized central atom model was introduced into the description of molten slag and applied for the slag database. The effects of operating conditions on V distribution ratios between slag and hot metal/semi-steel were analyzed and compared with the plant data. The simulated results could reproduce the variation of V distribution ratios with slag temperature and composition and provide the guidance for operators to control V distribution behavior for the better process operation.

期刊介绍： High Temperature Materials and Processes offers an international publication forum for new ideas, insights and results related to high-temperature materials and processes in science and technology. The journal publishes original research papers and short communications addressing topics at the forefront of high-temperature materials research including processing of various materials at high temperatures. Occasionally, reviews of a specific topic are included. The journal also publishes special issues featuring ongoing research programs as well as symposia of high-temperature materials and processes, and other related research activities. Emphasis is placed on the multi-disciplinary nature of high-temperature materials and processes for various materials in a variety of states. Such a nature of the journal will help readers who wish to become acquainted with related subjects by obtaining information of various aspects of high-temperature materials research. The increasing spread of information on these subjects will also help to shed light on relevant topics of high-temperature materials and processes outside of readers’ own core specialties.
