Modeling the Impact of Varying Levels of Inclusion Adhesion on Deposition in a Pilot‐Scale Nozzle

steel research international, Volume 96, Issue 3, March 2025.
Inclusion deposition is the dominant mechanism in nozzle clogging of submerged entry nozzles. Previous modeling attempts of inclusion deposition have assumed that any contact between the inclusion and nozzle wall results in adhesion. In this work, an Eulerian‐Lagrangian simulation with a stochastic adhesion model is used to study the effects of ...

PIV on Steady/Unsteady Flow Characteristics of Three‐Flow Tundish

The Journal of Engineering, Volume 2025, Issue 1, January/December 2025.
This study develops a hydraulic simulation system with adjustable flow rates and controllable liquid levels, using PIV velocity measurement to quantitatively assess the flow characteristics of the tundish during non‐steady‐state flow processes. ABSTRACT The non‐steady working state of the tundish, caused by the ladle changeover process, represents a ...

Tundish Cover Flux Thickness Measurement Method and Instrumentation Based on Computer Vision in Continuous Casting Tundish [PDF]

Mathematical Problems in Engineering, 2013
Thickness of tundish cover flux (TCF) plays an important role in continuous casting (CC) steelmaking process. Traditional measurement method of TCF thickness is single/double wire methods, which have several problems such as personal security, easily affected by operators, and poor repeatability.

Overview of application of automated SEM/EDS measurements for inclusion characterization in steelmaking

MetalMat, Volume 1, Issue 2, December 2024.
This paper reviews the use of the automated scanning electron microscope equipped with the energy dispersive spectroscope (SEM‐EDS) to analyze non‐metallic inclusions which are found in steel. Historical developments and further refinements of this method have been documented.

A Comparison of Selected Methods of Graphitizing Inoculation Applied after the Spheroidizing Treatment [PDF]

, 2012
The work compares the effectiveness of selected methods of graphitizing inoculation applied after the spheroidization in the slender tundish ladle of 1 Mg capacity. The inoculation was carried out according to the three various options. The first one was

Modeling on fluid flow and inclusion motion in centrifugal continuous casting strands [PDF]

, 2016
During the centrifugal continuous casting process, unreasonable casting parameters can cause violent level fluctuation, serious gas entrainment, and formation of frozen shell pieces at the meniscus.

Bubble Characteristics Required for the Complete Removal of Alumina Inclusions from Steel Melts

steel research international, Volume 95, Issue 11, November 2024.
Illustration of burst (or collapsed) microbubbles of argon trapped within a “flash‐frozen” sample of low melting point alloy (freezing point +57 °C), following rapid dipping and withdrawal of a cooled copper bar (≈at −100 °C) from the bath of the molten metal alloy. There, the submerged gas injection system is subjected to rapidly shearing metal flows,

Influence of design parameters of tundish and technological parameters of steel continuous casting on the hydrodynamics of the liquid steel flow

Metalurgija, 2014
Hydrodynamic conditions occurring in the tundish are strictly connected with the equipment of its working zone. On such conditions influence also many factors such as: the amount of steel present in the working zone, the velocity of steel casting.

Physical and mathematical modeling of inclusion behavior in a tundish with gas curtain

REM: International Engineering Journal, 2020
Gas injection in the tundish has been considered as an alternative to optimizing inclusion removal from steels. In the present study, physical and mathematical modeling were used to investigate the effect of gas injection in the tundish on the inclusion ...

Uncertainty Quantification in Modeling Mold Heat Transfer in Steel Continuous Slab Casting with CON1D

steel research international, Volume 95, Issue 11, November 2024.
The accuracy of computational models depends on uncertainty of the input data. This work conducts a sensitivity analysis of the CON1D model of solidification heat transfer in a steel continuous slab‐casting mold. Results identify the parameters which are critical to defect‐relevant outputs: mold heat flux, shell thickness, surface temperature, and mold
