• Continuous casting
• Solid shell thickness
• Analytical solution

A new analytical formula for the estimation of solid shell thickness over the length of a continuous casting mould has been developed. The precision of this formula was experimentally compared to that of the classic analytical solution of Stefan and the results of finite difference (FDM) and finite point (FPM) models of the process. The results showed that the new approach estimated the thickness of the solid shell along the continuous mould with greater precision than the Stefan solution and that the precision of the new approach was comparable to those of the FDM and FPM approaches. Therefore, despite its simplicity, the equation has potential to be used as a quick, inexpensive and relatively accurate tool to estimate the thickness of the solid shell in continuous casting moulds and some other solidification processes.
