摘要

HIsmelt process is a clean and efficient iron-making technology. The production of the first HIsmelt commercial plant of China, which was built in 2016, is stable at present, and remarkable results have been achieved in environmental protection and production cost aspects. The energy efficiency and its main influencing factors of HIsmelt process were systematically analyzed in this paper, combining with China's HIsmelt plant production practice. It has been pointed out that the main restrictive factors are the high efficient utilization of high temperature and low calorific value SRV off-gas to further improve the energy efficiency of HIsmelt. It introduced the process improvement and optimization of the HIsmelt plant in China, around the hot air blast position control, iron ore powder preheating, gas purification, and waste heat recovery.
