Abstract

The invention provides a smelting device and a smelting method for iron ore containing lead and zinc, and belongs to the technical field of iron ore smelting. The smelting device comprises a smeltingfurnace, a feeding mechanism, a discharging mechanism and a lead discharging mechanism, wherein the smelting furnace is in a long strip shape and is horizontally arranged in a blind hole formed in theground, an included angle is formed between the smelting furnace and the horizontal plane, the smelting furnace is used for smelting the iron ore containing the lead and the zinc and producing moltenlead, molten iron and a zinc oxide crude product, the feeding mechanism is used for conveying the iron ore containing the lead and the zinc into the smelting furnace, the discharging mechanism is used for receiving the produced materials, and the lead discharging mechanism is used for discharging the molten lead produced in the smelting furnace. Compared with blast furnace smelting, the smeltingmethod for smelting the iron ore is high in reaction speed and constant in temperature. The smelting device and the smelting method for the iron ore containing the lead and the zinc have the technicaleffects that the long-strip-shaped smelting furnace can be used for smelting the iron ore with low iron grade and high lead and zinc content, and the reaction is stable in the smelting process.

Description

technical field [0001] The invention belongs to the technical field of iron ore smelting, and more specifically relates to a lead-zinc-containing iron ore smelting device and a smelting method. Background technique [0002] Iron ore smelting mainly adopts the blast furnace smelting process. The development trend is that the capacity of the blast furnace is getting larger and larger. Most of the blast furnaces with a large capacity use concentrated materials. The quality standards for raw materials are very high, and high-grade iron with low lead and zinc content is required. ore. The domestic supply of high-grade iron ore with low lead and zinc content is seriously insufficient, most of which are imported, and the price of iron ore with 65% iron content is also very high. [0003] Domestic low-grade hematite and limonite reserves are abundant and the price is low. Even if the price is low, it is economically unreasonable to adopt the blast furnace smelting process. [0004...
