There is a strong need for the development of innovative processing methods to ensure a strong and competitive technological base for the steel industry in the future. The liquid oxysulfide phase in the iron-oxygen-sulfur system could function as a smelting medium for the production of metallic iron from oxidic and sulfidic ores. Potentially, the smelting process could be carried out at temperatures that are several hundred degrees below those in the blast furnace hearth and in steelmaking furnaces. The technology that could be based on oxysulfide smelting could have many advantages, some of which are high volumetric throughput, conservation of energy, and production of a very pure raw material for subsequent processing into steels. It is possible that the pure iron product might lead to completely new kind of steels, and eventually new methods of processing steels. A physic-chemical study will be undertaken of the thermodynamics and kinetics of reactions and processes that would be of generic importance in the development of possible methods for the bath reduction and smelting of iron ores in which the bath would be liquid oxysulfide phase in the Fe-O-S system.

迫切需要开发创新的加工方法，以确保未来钢铁行业具有强大和具有竞争力的技术基础。铁-氧-硫体系中的液态硫氧化物可作为氧化矿和硫化矿生产金属铁的熔炼介质。潜在地，冶炼过程可以在比高炉炉缸和炼钢炉低几百度的温度下进行。基于硫氧化物冶炼的技术可能有许多优点，其中一些优点是体积产量高，节约能源，并生产出非常纯的原材料，供后续加工成钢。纯铁产品有可能产生全新的钢种，并最终产生新的钢铁加工方法。将对反应和过程的热力学和动力学进行物理化学研究，这些反应和过程对于开发可能的熔融还原和熔炼铁矿石的方法具有普遍意义。在Fe-O-S体系中，熔池将是液态硫氧化物相。
