In this simulation you will play the role of plant metallurgist in charge of continuous casting operations. The aim of the simulation is to successfully sequence cast three ladles meeting the specified criteria of surface quality, internal quality and inclusion content. You should also aim to minimize the cost of the whole operation.
Prior to casting, you will need to carefully select various parameters, for example:
- Steel grade
- Target casting speed
- Secondary cooling
- Mold oscillation
Having selected these parameters you are tasked with ordering three ladles of steel from the secondary steelmaking shop. This step involves deciding on the liquid steel temperature and estimated arrival time. Once the simulation begins, you can control the flow of liquid steel between the ladle, tundish and molds. As the strand emerges, you can flame-cut it into lengths. And try at all times to avoid a breakout of liquid from the mold!

This completes the current section. If necessary, please ensure that you have achieved the learning outcomes for this section:
- Describe the main components and layout of slab, bloom and billet casters
- Explain the functions of the tundish and mold
- Explain the purpose of mold oscillation, and the effects of oscillation stroke, frequency and casting speed
- Describe and sketch typical temperature profiles for the liquid steel in both ladle and tundish
- Define the terms bulging, misalignment and bending/straightening strains and explain the main parameters that affect each
- Successfully perform a 3-ladle sequence cast in a continuous casting simulation
