steel research international, EarlyView.Vibration signals are generated by argon gas injection in molten metal and are measured in both industrial and laboratory ladles. Distinct frequency bands are identified, corresponding to bubble formation and rupture. The results demonstrate that vibration analysis can provide valuable insights into bubble dynamics and support optimization of gas ...

Alloying Strategies for Secondary Hardening in High‐Boron Cold Work Tool Steels: A Comparative Study
steel research international, EarlyView.The influence of tungsten, vanadium, manganese, and silicon on the microstructure and tempering behavior of high boron tool steels is investigated. It is shown that tungsten contributes very little, whereas vanadium leads to tempering carbides, detected by atom probe tomography . Manganese and silicon enable solid solution strengthening.

Evaluating Plasma Torches as a Low‐Decarburization Preheating Method for MgO–C Refractory Linings
steel research international, EarlyView.This study evaluates direct current (DC) plasma torches using nitrogen as an alternative preheating method for magnesia‐carbon (MgO–C) refractory‐lined ladles. Full‐scale trials at 0.7 and 1.5 MW are compared to conventional gas burner. Plasma‐heated samples show lower decarburization and improved surface integrity due to partial sintering and reduced ...
