Ferrochromium Slag

Analysis of forming chromium-bearing ferroalloys production waste in Russian Federation was performed. Chemical, phase, fractional compositions and physico-chemical, technological properties of high-carbon ferrochromium slag were defined. Physico-chemical, thermo-mechanical and thermo-physical properties of fire-resistant materials, obtained from ferrochromium production slag and dust, were researched. It was shown that researched waste may be utilized as raw for fire-resistant materials production. Because of their chemical and phase composition, researched materials may be utilized for production of forsterite-spinel-based and forsterite-spinel-periclase-based fire-resistant materials. Technological properties of researched materials allow obtaining dense strength fire-resistant materials. Such fire-resistant materials are promising in the field of ferrous metallurgy (lining up furnaces, ladles and overflow launders in ferroalloys production).

The austenite/pearlite growth interface in a model alloy steel (Fe-1lMn-0.8C-0.5V nominal wt%) is being studied in an attempt to characterise the morphology and mechanism of VC precipitation at the growth interface. In this alloy pearlite nodules can be grown isothermally in austenite that remains stable at room temperature thus facilitating examination of the transformation interfaces. This study presents preliminary results of thin foil TEM of the precipitation of VC at the austenite/ferrite interface, which reaction, termed interphase precipitation, occurs in a number of low- carbon HSLA and microalloyed medium- and high- carbon steels. Some observations of interphase precipitation in microalloyed low- and medium- carbon commercial steels are also reported for comparison as this reaction can be responsible for a significant increase in strength in a wide range of commercial steels.The experimental alloy was made as 50 g argon arc melts using high purity materials and homogenised. Samples were solution treated at 1300 °C for 1 hr and WQ. Specimens were then solutionised at 1300 °C for 15 min. and isothermally transformed at 620 °C for 10-18hrs. and WQ. Specimens of microalloyed commercial steels were studied in either as-rolled or as- forged conditions. Detailed procedures of thin foil preparation for TEM are given elsewhere.
