According to the comprehensive utilization of 300 series and 400 series stainless steel dust (SSD), and the dephosphorization of the reclaimed Cr-Ni contained hot metal, an experimental method of smelting reduction in iron-bath and oxidational dephosphorization was studied. The result shows: The yield rate of Cr in 300SSDand 400SSDis 98.13% and 98.39% respectively, the yield rate of Ni is almost 100%; During the dephosphorization, through the BaO and CaO-BaO based dephosphorizer has a higher Dephosphorization rate, it can bring pollution problems and the cost is too high, however, under some circumstance when the requirement of phosphorus content is not critical, the CaO based dephosphorizer can also achieved the dephosphorization goal.

The PETALE experimental programme in the CROCUS reactor at EPFL intends to contribute to the validation and improvement of neutron nuclear data in the MeV energy range for stainless steel, particularly in the prospect of heavy reflector elements of pressurized water reactors. It mainly consists of several transmission experiments: first, through metallic sheets of nuclear-grade stainless steel interleaved with dosimeter foils, and, successively, through its elemental components of interest – iron, nickel, and chromium. The present article describes the study for optimizing the response of the dosimetry experiments to the nuclear data of interest.

Reduction kinetics of stainless steel slag in iron bath smelting reduction was studied at the temperature of 1500°C ~ 1650°C. It was concluded that the reduction process consisted of two parts. That is to say smelting reduction was controlled by stainless steel slag melting initially and by interface reaction later. In order to increase smelting reaction rate, the melting point of slag should be decreased at the first stage and adjust the liquidity of slag at later stage. Smelting reaction rate will be accelerated by means of optimize the slag content. The optimal reduction result that all most all of the chromium in slag been recovered was obtained in temperature was 1500°C, basicity of slag was 1.0~1.2, the value of Al2O3+MgO was 25%.

Abstract Reflectance infrared studies of the oxidation of Types 304, 316, and 410 stainless steels, in oxygen at various temperatures, are described. Similar studies, directed toward the interpretation of the stainless steel oxide reflectance spectra, are presented for iron, nickel, molybdenum, and chromium. The value of the technique in providing a record of oxide compositional changes with time and temperature is demonstrated. It was concluded that Fe2O3 is the dominant constituent of oxide films formed on the three stainless steels at 400 to 500 C. At 850 C, chromia-iron oxide spinels, Fe2O3 and Cr2O3 were observed on Types 304 and 316 stainless steel, while chromia rich spinels or Cr2O3 formed on Type 410 stainless steel. Appreciable concentrations of nickel oxide on Types 304 and 316 stainless steel or molybdenum oxides on Type 316 stainless steel were not detected at temperatures up to 850 C. The formation of minor oxide constituents in both the stainless steel and component metal oxide films is discussed.
