الملخص

A scientific study investigating the continuous casting of steel for square section in Helwan Met. Company and the surface defects formation during this process. The cooling in continuous casting and its influence on solidification parameters were studied . also, the problem of rupture of billets skin in the mould and the effect of the different factors were investigated. The study includes an experimental part for determining the solidification coefficient in the mould and in secondary cooling.
