Hot metal pretreatment is the technology that removes the impurity elements in hot metal or recovers the valuable elements from the hot metal before hot metal is charged into the steelmaking furnace. Hot metal pretreatment comes in two types: common hot metal pretreatment and special hot metal pretreatment. Common hot metal pretreatment includes pre-desiliconization, pre-desulfurization, and pre-dephosphorization of hot metal. Special hot metal pretreatment is the treatment process that is intended to refine and purify the special elements in the hot metal or to comprehensively utilize the resources, e.g., extraction of vanadium, niobium, and tungsten from hot metal.
Hot metal pretreatment technology started from the external hot metal pre-desulfurization treatment. In 1877, A. E. Eaton et al. used this technology for treatment of rejected pig iron. Pre-desiliconization and pre-dephosphorization of hot metal started in 1897, when B. Till et al. of the UK used an open-hearth furnace for...
