简要阐述了澳大利亚Kwinana厂HIsmelt工业装置3年多的生产实践,指出了生产过程中暴露出的一系列问题,认为HIsmelt工艺技术是可行的,但需要系统优化。结合我国首座HIsmelt工业装置的设计和建设实践,从炉缸耐材、矿粉预热、煤气净化、矿煤喷吹等方面,提出了HIsmelt工艺优化的主要技术路径。从SRV大型化、全氧冶炼、钒钛矿冶炼等方面,简要阐述了HIsmelt技术的最新进展。
The production practice of HIsmelt industrial plant in Kwinana plant in Australia for more than three years is briefly described. A series of problems exposed in the production process are pointed out. The HIsmelt process technology is feasible but the system optimization is needed. Combined with the design and construction practice of the first HIsmelt industrial plant in our country, the main technological path of HIsmelt process optimization is put forward from the aspects of refractory of refractory furnace, slag preheating, gas purification and coal injection. From the SRV large, all oxygen smelting, vanadium titaniferous smelting and other aspects, briefly described the HIsmelt technology, the latest progress.
