Abstract A technology for integrating three steps (casting ingot, heating and hot rolling) in metallic material production together by means of one single production line includes such steps as making the molten metal flow through launder, technical processing area and hot injection mould to obtain a reasonable cross section and size for the least number of rolling passes, cooling to obtain molten ingot with hard surface shell, drawing it into magnetically suspending-cooling-crystallizing area for crystallization, and hot rolling.
