ABSTRACT:
A hot saw cutting type continuous rolling method comprises casting two strand billets continuously; cutting the billets to predetermined length by hot saws; directly feeding billet portions obtained by cutting onto a rolling line via a line connecting device; continuously welding and joining the billets portions by a flash butt welder to form a continuous billet; grinding and removing burrs at the welded portion of the continuous billet by a grinding machine; and continuously rolling the billet by a rolling mill group, after heating the continuous billet to a higher temperature by an induction heater. A hot saw cutting type continuous rolling apparatus is provided for performing the above-described method.
