Carbon Injection into Electric Arc Furnace Slags

Since 1907, when the first commercial Electric Arc Furnace (EAF) was built for steelmaking, the development route has gone through continuous evolution and ... The oxide components (slag) in EAF steelmaking are normally used to protect the furnace refractory and supply oxygen (O) for the chemical reaction with carbon.

Predicting ing slag quality in electric arc furnace ...

It depends on EAF structure, control, and ratio of charged material. Therefore, the trained ANFIS can predict the slag quality for specific EAF and using the power quality analyzer, which is used in the measurement stage. To predict the slag quality for different EAF models and for different power quality analyzers, there are two solutions.

Oxides in electric arc furnace slag (EAFS) | Rigaku

Electric arc furnace (EAF) steelmaking typically uses direct reduced iron or ferrous scrap as the feed materials. In the electric arc furnace lime (calcium) is added to remove silicates and phosphorus. With the addition of oxygen the ferrous materials are essentially melted, while the remaining material is changed to oxide forms. The slag by-product, also called EAFS, contains relatively ...

Slag ing in an Electric Arc Furnace

The EAF model was used to compute the slag composi-tion as a function of time and is shown in Fig. 2for Base Case (A) and Case (B). As opposed to oxygen steelmaking (OSM), e.g., LD, BOF, etc., in the EAF, the slag composi-tion does not change significantly with time. This was con-firmed by analysis of slag samples taken during the opera-tion.

Effect of Direct Reduced Iron (DRI) on Dephosphorization ...

the slag was proportional to DRI addition. The excess free energy of P 2O 5 increased with the increasing SiO 2 content in slag. A higher DRI content made dephosphorization difficult by decreasing the basicity and stability of P 2O 5 in the slag. Therefore, when using DRI in EAF process, it is very important to control the basicity of slag.
