Method for the continuous casting of long products and relative continuous casting line

The continuous casting method of long shape, product; the crystallizer and downstream seat is of a uniform and by at least the 4m/Min speed of the casting of the bending spray continuous casting machine arranged out at least 12% section of the liquid core situation without cutting locating ruler is matched to the horizontal section, the liquid core of the inner pouring inlet heat preservation and pre-heating device coagulates completely; then, the cast level of the foam and flash heating device, before, a without interrupt the processing of the situation the casting to is connected with the rolling mill. The shape of continuous casting production line comprises a continuous, heat-preserving and a pre-heating device, foam and flash heating device and rolling mill; the upper part and online device, the casting extended to the rolling machine from the automatic is continuous.
