In the paper a inner-outer couple cooling technology of molten steel for 1240×200mm slab continuous casting, that is to set an inner cooler-U shape pipes in the mold, is put forward in order to enhance the efficiency of transmitting heat and improve the flow status of molten steel. The flow status of molten steel in inner-outer couple cooling mold is simulated by using fluid dynamics software. It is found that setting inner cooler in the mold can make molten steel flow status even, which partly act as electromagnetic trig and is favorable to inclusion in molten steel floating up.

A coupled numerical simulation of magnetic field and flow field was conducted basing on Φ250mm bloom during continuous casting with electromagnetic stirring.The distribution of the flow field was analyzed in different current and frequency.At the same current,the velocity first decrease and then increase as the frequency increase along the casting direction.At the same frequency, tangential velocity is dominant in the radial of EMS center,velocity increase with the current. Considered the results of numerical simulation,the optimized EMS parameters of Φ250mm bloom are the stirring current of 480A and the stirring frequency of 3Hz.

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.
