of a base metal in consideration of equilibrium relation of C-Cr-temp. CONSTITUTION:In charging lumpy carbonaceous substance in a melting furnace, upper addition is usually employed. In this case, as a condition for melting Cr- containing scrap, it is important that melting is advanced in a ...
PURPOSE:To continuously manufacture molten steel of fixed C content and temp. by controlling recarburizing amt. in a melting furnace and oxygen blowing amt. in a refining furnace according to the detected values of the concn. of C and Si in molten metal at the outlet of the melting furnace...
In this study, yttrium as desulfurizer on the purification of Ni–20Co–20Cr–10Al–Y alloy during vacuum induction melting (VIM) process using Y2O3crucibles was investigated experimentally. It is found that Y plays an important role on the desulfurizing of the NiCoCrAlY alloy. Without any ad...

PURPOSE:To execute decarbonizing refining under restraining oxidation of Cr in a top-bottom blowing refining furnace, by specifying uniform mixing time for molten steel of high chromium alloy steel and quantifying relative relation between oxygen supplying velocity and transition of C and Cr. ...
After completing the oxygen-blow refining, successively, the energizing is executed so that the power consumption becomes the value in the range of 40-70kWh/ton of chromium-containing molten iron. By this method, since the temp. raising term of the chromium-containing molten iron can be ...
, the period when a chromium-containing raw material is charged into an electric furnace once or plural times and a charged chromium-containing raw material is melted is defined as a melting period, and the period when the melted chromium-containing raw material is heated to the preset temp. ...
PURPOSE:To utilize carbonaceous substance as a heat source in good efficiency and to prevent the oxidative loss of Cr in scrap, by a method wherein the carburizing Cr is preceded in consideration with equilibrium relation of C-Cr-temp. and, thereafter, carburization and the melting of scrap ...
exhaust gas from a ferrochromium melting and reducing furnace from an inlet 8 while the high temp. of a preliminary reducing furnace 10 provided to the lower part is further introduced through a conduit and a dispersing plate 9 to heat the Cr ore and the spinel structure of the Cr ore is...
