Method for removing a molten metal main portion from a metal-meting container through an outflow opening embodied in the bottom surface thereof, a metal-melting container and a flowchart of main opera

The invention relates to metal manufacture in ferrous and non-ferrous metallurgy and is represented by the example of steelmaking in arc steel-smelting furnaces. Before the start of chamber emptying the method provides level ascending of metal input into the outlet and retaining of this position till the end of chamber discharging. After that the initial position of input level must be restored, at that the leaving metal flows are separated from the metal flows ascending to the input of the outlet by the wall the height of which determines the ascending value of level of metal coming into the outlet. The method provides an influence on chemical composition of molten metal by delivery of alloy element into the metal flows leaving the chamber that is carried out together with feeding of inactive or inert gas. There is contemplated preliminary circulation of these gases through the metal situated over the outlet and inside the clearances for metal passing. The smelting chamber for method of its discharging conta
