Physical Simulation on the Liquid Metal Flow in FC-Mold of Slab Continuous Casting

Abstract

The flow state and velocity distribution of liquid metal in the FC-Mold and the influence rules by the magnetic flux density have been investigated when electromagnetic brake adopted, applying mercury as medium to simulate molten steel in the continuous casting process. The velocity measurement has been completed by the Ultrasonic Doppler Velocimeter (UDV) under various magnetic distribution and the influence laws of magnetic flux density on the liquid metal flow in the mold has been analyzed. The experimental results indicate that, when the upper and lower magnetic flux density is 0.18T and 0.5T respectively, a preferable control effect can be obtained, not only the free surface fluctuation can be compressed, but also a plug flow can be rapidly formed.

Modeling and experiment of slag corrosion on the lightweight alumina refractory with static magnetic field facing green metallurgy

“…The Volume of Fluid (VOF) model was applied to describe a two phase flow comprising liquid and gas (e.g. slag and air), and the flow resistance coefficient equations (2) and 3 e e porosity of porous medium, %, A 1 and A 2 are empirical constants which were determined by permeability test [29], for the aggregates, A 1,ag is 1216.25 and A 2,ag is 37945.24; for the matrix, A 1,ma is 412.88 and A 2,ma is 34707.80.…”

“…Electromagnetic field is widely discovered and applied in metallurgy and other high temperature processes, and its thermal and mechanical effects are important means of producing special steels and improving the quality of steel [1,2]. Refractory is an essential material to ensure the production, operation, and technological development of high temperature industries.…”
