Understanding the thermomechanical behaviour of an alloy during the Direct Chill (DC) casting process is essential to alleviate the defects in the casting. In this work, conventional direct chill casting process is numerically modelled for evaluating

Direct chill (DC) casting is the widely used technology for the production of ingots or billets of nonferrous alloys. Non-uniform thermal gradients generated during the process play a predominant role in generation of cracks within the billet. In the

At the end of the hot rolling process, quenching is deployed for obtaining the desired microstructure and mechanical properties. During the quenching of aluminium plates, it is essential to optimize the process parameters such as the plate speed and

Integrated casting and rolling in a series production line is well established for the non-ferrous metals through the use of twin-belt casting technology. However, this twin-belt casting with high mass flow is not yet commercialized in the continuous

A temperature based Finite Element Model is developed to estimate the evolution of temperature, shell growth profiles and solidification length of a solidifying ingot in a twin-belt caster. The model is based on the 2-D slice which travels through th

A semi-analytical model is presented to find the solidification length of continuously cast metals. An existing theoretical solution for solidification in an infinite slab, which is maintained at constant surface temperature is extended to a finite s
