Description

Technical Field

[0001] The embodiments of the present disclosure belong to the technical field of waste slag screening equipment, and specifically relate to an electric furnace slag waste screening equipment. Background Art

[0002] The slag produced in the electric furnace steelmaking process is different due to the different refining methods and different types of steel smelted. It is mainly divided into oxidized slag produced in the electric furnace melting period and oxidation refining period, and reduced slag produced in the reduction refining period and ladle refining. When making steel in an electric furnace, the scrap steel is first heated by electric arc to melt it, and sometimes molten iron or direct reduced iron is added, and then lime and flux are added. Oxygen is blown in from the beginning of melting to oxidize impurities in the steel, adjust the carbon content, and form oxidized slag. After the oxidized slag is discharged, reduction refining, desulfurization and deoxidation are carried out in the electric furnace or ladle to produce reduced slag.

[0003] Electric furnace slag is solid waste discharged during the process of smelting metals in electric furnaces. Its main components are oxides such as calcium, iron, copper, silicon, magnesium, aluminum, manganese, and phosphorus. Common types include steel-making electric furnace slag and copper-smelting electric furnace slag. The main way to utilize electric furnace slag is to recycle it within the smelting company. It can be returned to the furnace as a smelting raw material, or used for highway and railway subgrades, as well as for the production of cement raw materials and soil improvement.
