الملخص

A study devoted to the consideration of the solidification process in the continuous casting machines both theoretically and practically. The theoretical part investigates the factors affecting solidification of rimming, semi-killed and killed steels. As for the experimental part , it is based on the determination of the coefficient of crystallization under the operating conditions of the continuous casting machine at H.M.C as well as finding out the most suitable casting speed. The study also contains an economical part.
