Considerable work has been done on the development of advanced process control for the Electric Arc Furnace (EAF) steelmaking process. Historically, many control systems have been employed which rely on static heat balance calculations coupled with power input profiles to generate recipe driven control models. Steelmakers have desired to have continuous information about the gases exiting the f...

The structure and viscosity of the dephosphorization slag in new double converter steelmaking process with low basicity at temperature range 1573 K–1723 K are studied high-temperature laboratorial experiments. With increasing end dephosphorization, viscosities different slags decrease rapidly first, then slowly, activation energies increase. values Non-Bridging Oxygen per Silicon (NBO/Si) decre...

The foaming process is an important part of the electric arc furnace (EAF) steelmaking process. It can promote thermal efficiency and reduce refractory consumption. FeO a key material used during Unlike with other components in forming slag, amount be controlled by oxygen or carbon injection. Therefore, adjusting content most economical mode adopted for EAFs In this study, influence on physical...

In order to achieve the purpose of high-efficiency dephosphorization by single-slag method during combined blown converter steelmaking process, CaO-SiO2-FetO-MgO-MnO-P2O5 slag system was taken as research object, and slag-forming route studied. The effects compositions on liquidus contour map phosphorus distribution ratios (recorded Lp) were calculated thermodynamics software FactSage, then the...

Basic oxygen steelmaking (BOS) slag, a product of hot metal element (e.g., Si, Mn, Fe, P) oxidation and flux (e.g. lime, dolomite) dissolution, plays critical role in the production high-quality crude steel, although its behavior inside BOS vessel (formation reaction with droplets gas) is still not clear recycling has always been challenging. Herein, examples BOS-slag-related research conducted...
