Slag foaming is a very important phenomena in the operation of the Electric Arc Furnace due to multiple benefits. It has been extensively investigated from an academic view point, however there are still many unresolved issues dealing with the real conditions that promote these phenomena. I many of the previous investigations the gas is artificially injected, rather than created at the...
The technologies related to EAF steelmaking have continuous developments aiming the improvement of the process performances and of the environmental impact mainly through the reduction of energy consumption, the increase of productivity, the increase of metallic yield and promoting the reduction of CO2 emissions.
These improvements pass strongly by improved capability to monitor and control...
Electric arc furnaces (EAFs) have become a key steelmaking technology in recent years. Today, more than 70% of steel produced in the United States comes from EAFs, which can reduce carbon emissions by up to 55–60% compared with the traditional blast furnace–basic oxygen furnace route. This makes EAFs a critical pathway for decarbonizing the steel industry. Despite these advantages, further...
We present a design and the results of several trials of a Radar level probe. This probe measures the slag level during the EAF operation. The measured level can be compared to the model result of the slag foaming indication. The trend of the slag level indicates the end-of-batch by exactly identifying the rapid increase of the slag level. By accurately measuring the foaming level, batch to...
The Ladle Furnace (LF) serves as a secondary metallurgical process unit for adjusting the composition and temperature of molten steel for casting. Changes and transformations in the steel industry—such as green steel and digitalization—emphasize the need for real-time process control and enabling measurement solutions. This work aimed to study how optical emission spectroscopy (OES) data can...
For over 90 years, Huisman has been active in heavy offshore lifting, engineering cranes with capacities up to 10,000 tons.
Today, we are adding a new chapter—one that aligns with the steel industry’s bold transformation toward low-emission steel production. As electric arc furnaces and hydrogen-based DRI technologies reshape steelmaking, we asked ourselves: how can lifting technology...
