1 C3: LIMMCAST: Modelling of steel casting S. Eckert 1, R. Schwarze 2 1 Helmholtz-Zentrum Dresden-Rossendorf (HZDR), D Dresden 2 TU Bergakademie Freiberg, Inst. für Mechanik und Fluiddynamik, D Freiberg Text optional: Institutsname Prof. Dr. Hans Mustermann Mitglied der Leibniz-Gemeinschaft
2 Motivation The properties of the turbulent flow of the liquid steel influence the quality of the final product and the efficiency of the process. Problem - Accidental flow limits the casting speed and causes surface defects and inclusions of impurities Application of magnetic fields (brakes and stirrers) - Magnetic fields are in industrial use, but, further improvement of efficiency requires a better understanding of the complex interaction between magnetic field and flow Seite 2
3 Objectives - Physical modeling of the continuous casting using low-melting metal alloys (HZDR) - Corresponding numerical modeling (TU-BAF) - Flow measurements in the mould, submerged entry nozzle (SEN) and tundish - Impact of various magnetic fields - Development of suitable numerical models, code validation - Optimal configurations for magnetic systems for melt flow control LIMMCAST- Program (HZDR) - Three experimental facilities (LIMMCAST, mini-limmcast, X-LIMMCAST) Seite 3
4 LIMMCAST Simplified model of the continuous casting process Use of Sn60Bi40 alloy as model fluid (T Liq = 170 C) Operating temperature at 200 C up to 350 C Flow rate 2.5 l / s Velocity in nozzle 1.3 m / s Seite 4
5 mini-limmcast Two-dimensional velocity mapping in the mould Influence of the wall conductivity (0.5 mm brass plates) B max = 310 mt (Ha = 460), pole face: 180 x 40 mm² Magnetic field covers the whole mould width (level configuration) Hartmann number Ha = B 0R σ ρν Seite 5
6 US measurements of the mould flow 10 sensors in multiplexer mode Time resolution ~ 5 Hz B = 0mT B = 310mT, Non-conducting mould B = 310mT, Conducting mould B-field Seite 6
7 US measurements of the mould flow Magnetic field influence on the flow: Change of the jet angle Formation of strong recirculation zones B = 0mT B = 310mT, Non-conducting mould B = 310mT, Conducting mould Seite 7
8 Local time series of the mould flow (a) (c) (b) Time series of the horizontal velocity for: B = 0 (solid lines), B = 310 mt in the non-conducting mould (dotted lines) and B = 310 mt in the conducting mould (dashed lines) Recorded at x = 24.5 mm and (a) z = -1 mm, (b) z = 19 mm, (c) z = 49 mm. Seite 8
9 CIFT at mini-limmcast Flow reconstruction in the mould from 2x7 fluxgate sensors at the narrow faces: Very intermittent two-phase flow behaviour Seite 9
10 Two-phase flow Open questions: Flow regime in the nozzle Bubble distribution in the mould Flow instabilities Seite 10
11 Two-phase flow in nozzle and mould Complex measurements possible: MIT in nozzle + CIFT in mould + pressure in SEN Seite 11
12 Numerical simulations (TU-BAF) Previous work Flow investigations in continuous casting machines for steel (several projects: DFG, industrial partners, cooperation with HZDR) Simulation of flow and solidification in steel melts (SFB 799, TP C1) Current issues RANS/URANS model for mini-limmcast FVM method, OPEN FOAM Turbulence models: SST k-ω, Reynolds stress Validation using experimental data Seite 12
13 Numerical simulations (TU-BAF) Status Qualitative features of the flow Complex interaction submerged jet vortices Next steps URANS Validation of the Reynolds stress model Extension of the turbulence model Seite 13
14 Work packages Flow measurements wit DC-field (variations: magnetic field parameters, flow rate, SEN geometry, wall conductivity, ) Two-phas flow: flow regime inside the SEN, influence of the gas injection on the onset of instabilities Numerical simulations: MHD turbulence modeling, validation using the experimental data obtained at LIMMCAST Links to other projects within LIMTECH A3, A4, A5, C1, C4 and YIG Staffing issues S.
