Mathematical and physical simulation of a funnel thin slab continuous casting machine of a Mexican plant
A Mexican plant wants to increase the speed of the continuous casting machine; however some problems had appeared, like oscillations and an increase of trapped inclusions in the final slab. The understanding of oscillations phenomena inside the funnel thin slab mould is essential to ensure constant molten steel delivery, better flow patterns control and consequently increase the shop productivity and quality of the final product. To achieve this, a series of actions has been taken. First, a novel tundish design is proposed in order to study the effects on the fluid dynamics without any internal device in it, as occurred in traditional ones. Also some design changes in the mold submerged nozzle are suggested in order to determinate the origin of the jets oscillations and fix it. Through mathematical and physical simulation for the tundish and the nozzle in the funnel mold in thin slab continuous casting machine the phenomenon is explained. A transducer is proposed not only to have an indication of the fluid dynamics of the mold and nozzle to avoid the oscillation phenomena, also to have an indication of the inclusions’ behavior once a relationship between the vibrations of the mold and the inclusions was found.
