Abstract

The invention discloses a flash smelting method of iron. A flash smelting furnace comprises a reaction tower, a furnace charge nozzle, a molten bath and a flue, wherein a reaction space is limited in the reaction tower, the furnace charge nozzle is arranged at the top of the reaction tower, the molten bath is arranged on the lower portion of the reaction tower and used for containing melt fallen from the space of the reaction tower after reaction and for a subsequent reduction reaction of the melt, and the flue is communicated with the reaction tower through the molten bath and used for discharging flue gas generated during the reaction. The flash smelting furnace in the embodiment can be effectively used for flash smelting of the iron.

Description

technical field [0001] The invention relates to the field of metallurgy. In particular, the invention relates to a flash metallurgy process for iron. More particularly, the present invention relates to a flash smelting furnace and a method of ironmaking using the flash smelting furnace. Background technique [0002] The blast furnace ironmaking method has a history of more than 200 years, and it is still the most basic ironmaking process in the world at present. It consists of pelletizing, drying, sintering, crushing, smelting and other processes, so the process is long, the investment is large, and the energy consumption is high. [0003] Therefore, the current ironmaking method still needs to be improved. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art. [0005] To this end, an object of the present invention is to propose a flash smelting furnace which is inexpensive to manufactu...
