The invention relates to the branch of ferrous and nonferrous metallurgy, namely to the method of continuous casting of core type billets. A method of continuous casting of corre type billets includesfilling of liquid metal from the intermediate ladle into the well of machine of continuous casting, cyclic extraction of billet from the mould of the machine of continuous casting and its cutting into the billets of identical length, in this case the efforts of extraction of billet from the mould of the machine of continuous casting P, at its cyclic motion, are maintained within the range P = k . pP, where k - coefficient of value 0.68-0.99; pP - maximum permissible effort of destruction of the cross section of graphite mandrel, Mn, and the value of effort P is adjusted by change of the value of step L, m. The invention provides for increase of the stability of the process of continuous casting and quality of internal surface of mandrel type billet of ferrous and nonferrous alloys.
