Many metallurgical functions such as dehydrogenation, decarburization, and inclusion
removal are achieved during Ruhrstahl–Heraeus (RH) treatment. The realization of these …

Inclusions can lead to various defects in the final steel products, and RH vacuum refining is
an effective and vital technology to remove inclusions from molten steel. By the …

In the current study, mathematical models were developed to predict the fluid flow and
motion of gas bubbles in the RH degasser. The multiphase model volume of fluid was …

Computational fluid dynamics (CFD) techniques and a 1: 7.5 physical model of an RH
degasser have been used to evaluate the flow of gas and metal inside an RH reactor for …

An Eulerian multi-fluid VOF model, the coupling of the Eulerian model and the “VOF”
interface tracking method, offered by ANSYS Fluent has been first applied to investigate the …

The improvement of mixing conditions in vacuum refining unit plays an important role in
enhancing the purity and decarburization of molten steel. A numerical simulation is …

A mathematical model has been established to simulate the gas–liquid two-phase flow in
the RH process. The effects of interphase forces and the bubble-induced turbulence on the …

In this work, the RH-BPI refining process was numerically simulated by establishing a
coupled gas–liquid-particle mathematical model. The deflection behavior of the gas-powder …

The bubble motion behavior and the inclusion removal during the argon injection
processing through the down leg of an Ruhrstahl–Heraeus (RH) unit have been investigated …

Sampling location is indeed essential to determine whether the sample is representative in
the RH vacuum refining process. In this study, in order to find a reasonable method to …
