    1. 225. EFFECT OF DIFFERENT PROCESS PARAMETERS ON NON-METALLIC INCLUSIONS DURING ELECTO-SLAG REMELTING OF A TEMPERING STEEL
      Reinhold Schneider (Univ. of Appl. Sciences Upper Austria)
      18/06/2019, 10:30
      Highlight
      The remelting behavior of the tempering steel 50CrMo4, was investigated with several experimental melts on a lab-scale ESR-plant. The investigated parameters included a variation of the slag compositions and the use of a protective nitrogen atmosphere. Variations of the slag composition comprised slags with different contents of CaF2, CaO and Al2O3 as well as a variation of the SiO2-content....

    2. 113. A STUDY OF THE MASS TRANSFER KINETICS DURING THE DISSOLUTION OF Ti-N PARTICLES IN LIQUID TITANIUM
      Prof. Steven Cockcroft (University of British Columbia)
      18/06/2019, 10:50
      Oral Presentation
      This paper summarizes the development of a computational fluid dynamics (CFD) model based on the commercial software package ANSYS-CFX, which has been used to examine the kinetics of dissolution of a single stationary Ti-N particle surrounded by moving liquid titanium. The model accounts for diffusional mass transport in the solid particle, the formation of a two-phase solid/liquid...

    3. 149. INFLUENCE OF SIDE ARCS ON THE SOLIDIFICATION OF A VAR INGOT
      Ebrahim Karimi Sibaki (Montanuniversitaet)
      18/06/2019, 11:10
      Oral Presentation
      Secondary metallurgical processes such as Vacuum arc remelting (VAR) are extensively used for production of metal ingots with superior quality. The complex VAR process involves a wide range of physical phenomena including heat transfer with phase change (solidification/melting), Plasma arc, and the interplay between flow and electromagnetic field known as magnetohydrodynamics (MHD). The...

    4. 128. NUMERICAL SIMULATIONS OF LIQUID STEEL ALLOYING IN THE THREE STRAND CONTINUOUS CASTING BLOOM TUNDISH
      Adam Cwudzinski (Czestochowa University of Technology)
      18/06/2019, 11:30
      Oral Presentation
      This paper aims to obtain fundamental information on chemical homogenisation process of liquid steel with alloy additions in the bloom tundish. For alloy feeding to liquid steel pulse step alloying method was applied. Author checked the effect of hydrodynamic conditions occurs in the internal working space of tundish on the process of alloy mixing with liquid steel. Within the work basic and...

    5. 20. INVESTIGATION ON BAND SEGREGATE FORMATION DURING THE ELECTROSLAG REMELTING OF H13 DIE STEEL
      Qiang Wang (Wuhan University of Science and Technology and Delft University of Technology)
      18/06/2019, 11:50
      Oral Presentation
      Band segregation has been found in the H13 die steel produced by the electroslag remelting (ESR) technology. Chemical and metallographic studies have been carried out on a one ton ESR ingot of H13 die steel, so as to understand the formation mechanism of the band segregation. The results indicate that the T.O content and S content decreased because of cleanliness improvement of ESR process....
