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).

Ferrochromium Slag

Ferrochrome slag, an essential component in stainless steel, is the by-product of ferrochromium production. The composition of the ferrochrome slag and leaching tests show that the chromium content, 3.68%, is high, although the data of leaching tests under normal conditions is very low. Leaching test was performed on an oscillating shaking table with ratio adjusted to 150r/min at L/S 8 and 80°C, during 5h. The maximum content of water-soluble Cr (Ⅵ) is 2.78μg/g (0.3475 mg/L) from ferrochromium slag under these conditions. The soluble (Cr6+ and Cr3+) content rise in the solidification process，with the increase of ferrochrome slag. The Water-soluble Cr (Cr6+ and Cr3+) under different cured times can’t be detected. The content of ferrochrome slag reached 10% is the best ratio by comprehensive consideration of water-soluble Cr (Ⅵ) of all processes, compressive strength and relevant national standards.
