Abstract

The invention provides a steel slag treatment device with a cooling sprayer, and belongs to the technical field of steelmaking slag treatment. The steel slag treatment device with a cooling sprayer comprises a cooling device, a lifting traveler, a tipping device, a screening device, a scrap steel bucket and a transition bin, wherein steel slag discharged from steel slag equipment is filled onto a steel slag ladle; the steel slag ladle is cooled by the cooling device; the steel slag is tipped in the tipping device and poured onto the screening device for screening; large-size scrap steel is screened out and transported to the scrap steel bucket for reutilization; and the screened slag is disposed in the transition bin and fed through a chain plate conveyer and a belt conveyer to a ball mill for secondary screening or directly transported for other purposes. The steel slag treatment device provided by the invention can avoid steel slag waste more effectively; and meanwhile, the steel slag treatment device prevents pollution to the external environment in the steel slag treatment process.

Description

technical field [0001] The invention belongs to the technical field of steelmaking slag treatment. Specifically, the invention relates to a steel slag treatment device with a cooling sprayer, in particular to selecting steel scrap from steel slag and solving the problem of dust. Background technique [0002] Steel slag is a by-product produced in the steelmaking process. The steelmaking workshop of Beihai Chengde Group adopts AOD furnace (argon oxygen refining method refining equipment) technology for steelmaking. Since AOD must be slag-extracted during smelting, while slag-extracting, Part of the molten steel will be brought in and mixed into the slag ladle; generally speaking, the amount of slag in AOD smelting stainless steel accounts for 20-25% of the total amount of stainless steel, and the amount of molten steel mixed into the slag accounts for about 2-3% of the total amount of stainless steel. Such data exists in major domestic steel mills, resulting in a lot of waste...
