Fabrication and Simulation of a Two‐stage Mold with Low Magnetic Shielding for Soft‐Contact Electromagnetic Continuous Casting

Soft-contact electromagnetic continuous casting is one of innovative technologies for the development of steel industry. In this paper, the present situation was reviewed from five aspects: the soft-contact mold material and structure parameter design, the electromagnetic field distribution, the meniscus shape and movement behavior, casting slab surface quality improvement mechanism and the method of magnetic fields imposed. The main questions of the technology were analysed, and the remarhable in the process of industrialization were pointed out.

Electromagnetic Continuous Casting

Using finite element method, the molten steel flow process in soft-contact electromagnetic continuous casting mold is simulated. The results show that the molten steel surface were affected by the electromagnetic force and shrink to the centre, near meniscus zone the flow velocity of steel increases and appears an obvious circumfluence, a large number of inclusion float and are absorbed by flux; on the other hand, the turbulent kinetic energy significant increases in circumfluence area, this exacerbates the reaction between flux and liquid steel, the initial size of the solidification organization are refined, and the surface quality of slab are enhanced.

Abstract. Soft-contact electromagnetic continuous casting is a new technology to improve the surface quality of billet. The soft-contact electromagnetic continuous casting mold heat transfer mechanism was discussed through the molten steel heat transfer process in the mold in this paper. The aspect that previous studies have not designed in the heat transfer process has been pointed out in the last. The researchers did not add the flux film as a heat transfer medium,but the slag in the mold is a very important thermal resistance actually.
