Introduction Vanadium is one of the most common alloy elements used in ferrous and non-ferrous alloy because it possesses unique properties of high tensile strength, hardness, and fatigue resistance [1...% in organic solution. However, high or low pH is unfavourable to vanadium leaching due to the performance of biological activity. The results in Figure 6(b) show employing Fe(II) in the Fe(III......
, then to reduce the ore to produce direct reduction iron (DRI), and finally to separate metal from the titanium-rich slag and obtain DRI with high quality. Some chloride wastes, such as iron chlorides... in the system; 2) reducing the vanadium free pellets after roasting for producing DRI; 3) separating the DRI from titano-rich slag. The left titano-rich slag can be used as the alternative of raw material......
be produced with bauxite containing high silica by Bayer process as well. Though there exist various kinds of calcium silicate hydrate, the formation and reaction behaviors havent been studied systemically in concentrated caustic solution yet. In the past, much research on calcium silicate hydrate was focused on the hydro-chemical technology at high pressure, and calcium silicate hydrate occurred......
Effect of Alloying Additions on the Oxidation of High Speed Steels under Dry and Wet Conditions () 摘要:An investigation has been carried out into the effects of chromium and vanadium content on the oxidation rate and on the adhesion of oxide scales grown on three different chemical compositions of high speed steels under dry and wet conditions. The oxidation tests were carried out......
