    摘要: A process for adjusting the composition of a liquid metal, such as steel, is provided wherein liquid metal is sucked up from a start receptacle into a reactor which is at a reduced pressure with respect to the start receptacle. First, the liquid metal is made to flow inside the reactor under conditions close to plug flow where it undergoes a metallurgical treatment. Next, after the liquid metal has been conveyed through the reactor it is completely discharged into a finish receptacle which is also at a reduced pressure with respect to the reactor. To insure thorough mixing, the reactor is divided into a plurality of cells, each of which has its own independent gas injector for agitating the liquid metal therein.

    摘要: Both a method and apparatus for producing molten steel are provided wherein ferrous materials rich in carbonaceous materials are fused in a first vessel of a single electric furnace having separate first and second vessels. The carbonized molten metal thus obtained is then pretreated in a separate pretreatment facility to remove contaminants and the pretreated molten metal is then decarburized in the second vessel of the electric furnace. The decarburization of the pretreated metal in the second vessel of the furnace avoids reintroducing contaminants into the steel by avoiding contact between the pretreated metal and the slag produced when the initial carbonaceous materials are fused. Preferably, the first and second vessels are two vessels of a single electric furnace having a single electric power source.
