Ferroalloys are one of the most important raw materials widely used in steelmaking processes. Depending on cleanliness ferroalloys, they can be an inevitable source impurities and nonmetallic inclusions (NMIs) products. Herein, five different industrial ferroalloys (FeTi, FeMo, FeW, MnN, FeCrN) investigated. This is done using 2D investigations polished cross sections ferroalloy samples 3D NMIs...

This study investigates the effect of different temperatures during deoxidation 42CrMo4 on nonmetallic inclusions (NMI). Tailoring NMIs by a modified temperature is last step before combination reactive and active steel melt filtration. Extensive investigations metallographic sections together with electrolytic extraction allow analysis inclusions’ size distributions, chemical compositions, mor...

Herein, the combined influence of reactive cleaning and active filtration on inclusion removal is investigated using numerical simulations. Carbon‐bonded ceramic foam filters with effect are inserted into steel melt to remove nonmetallic inclusions. In case cleaning, carbon can dissolve from melt. As a result, reacts oxygen surface form monoxide bubbles. The capture inclusions in terms its effe...

The control of formation nonmetallic inclusion and the characterization present basis improvement steel product properties lead to sustainable development in design new grades. In order produce steels with better machinability, such as AISI 303 grades, a modification inclusions carefully designed chemical composition is presented. Sulphur by creating sulphide reduces friction cutting resistance...

Nonmetallic inclusions are well known to influence product quality and process stability in the production of steel. A step that is very sensitive presence nonmetallic inclusion (NMI) continuous casting. Here, so-called clogging phenomenon can occur, resulting a distinct disruption casting decreased steel quality. The considerably contributes build-up deposits submerged entry nozzle provoking i...

Tracing by means of the light rare earths (REs), particularly La and Ce, is a state-of-the-art method used to track deoxidation products during steelmaking process. Traced heterogeneous multiphase inclusions are analyzed using scanning electron microscopy with energy-dispersive spectroscopy (SEM/EDS) perform 2D characterization. The sequential chemical extraction technique implemented for 3D in...
