When the steel has been teemed from the ladle to the tundish and then from the tundish to the mold, the steel starts to solidify inside a water-cooled copper mold. At first only a very thin shell is solidified and as time passes this shell grows so that it becomes thick enough to support the weight of the liquid steel. An oscillating mold is used whereby the withdrawing action brings the mold back up quickly so that the solidified steel separates from the mold.

Here you can explore the effect of mold oscillation parameters, casting velocity and powder viscosity on negative strip time, mold powder consumption, oscillation mark depth and mold acceleration.
