ABSTRACT:
Integrated plant (10) to convert a metallic charge continuously into semi-finished products such as billets, blooms, slabs, bars or ingots, which comprises in close cooperation a chamber (14) to pre-heat a controlled metallic charge, the chamber (14) including a burner (15) and a terminal feeder (16) feeding an electric furnace (17) with a controlled flow, and comprises also the electric furnace (17), a continuously functioning transformer (26), a multifunction manipulator (20) with two independent arms able to rotate circumferentially and to move vertically to handle two ladles (18) at one and the same time at least between a tapping station of the electric furnace (17) and a casting and tapping station (21), and at least one casting and tapping station (21) served by a tundish feeding liquid metal continuously, a station to refine the liquid metal in the ladle (18) being located between the tapping station of the furnace (17) and the tapping and casting station (21).
Smelting method obtained with the plant (10) of the claims hereinbefore, which feeds molten metal continuously at least to one casting statio (21) by means of two ladles (18) feeding a tundish alternately and starts with a pre-set and variable metallic charge, such metallic charge being fed continuously in the opposite direction to heating means in a pre-heating chamber (14), such charge feeding continuously with an adjustable flow an electric furnace (17) when liquid metal is tapped regularly and partially into ladles (18) able to move along a circumference, in which method the liquid metal is treated and refined in the ladle (18) before being delivered by one of the ladles (18) alternately into a tundish which transfers it continuously to the casting station (21) while the other ladle (18) is engaged in succession in operations of preparation, charging and refining, the cycle proceeding continuously without operating interference.
