Супер качествена феро титаниева бучка

There are several main methods for producing ferrotitanium. The raw materials for industrial production of ferrotitanium include titanium - iron concentrate (Fe - TiO₃), rutile (TiO₂), titanium dioxide (TiO₂), and waste titanium metal materials (Ti, Ti - V - Al, etc.). Among them, except for Отпадъчни титанови метални материали, останалите трябва да бъдат намалени чрез намаляване на агентите, за да получат феротитанови и титанови сплави .

Един общ метод е алуминотермичният метод . Тъй reaction. However, the produced ferrotitanium has a high silicon content. Using aluminum to reduce TiO₂ to form Ti is possible. But if the amount of aluminum is lower than the stoichiometric value, a large amount of TiO will be generated. TiO is more stable than TiO₂, and aluminum cannot reduce it. Adding CaO can prevent the slag - forming reaction of TiO and is beneficial to the reduction of TiO₂. Therefore, using aluminum to reduce titanium concentrate is the main method for producing ferrotitanium, and the obtained product has a low carbon content but high aluminum and silicon contents. Another method is the electro - silicothermic method. In this method, in an electric furnace, ferrosilicon is used to reduce the TiO₂ - FeO - CaO - CaF₂ melt, and composite alloys such as Fe - Ti - Si and Si - Ca - Ti can be produced. By adding other oxides or additional ferrous alloys, multi - element titanium composite alloys can be made. The third method is the electro - carbothermic method. In a small - scale electric furnace, coke is used as a reducing agent and lime as a flux to produce high - carbon ferrotitanium containing 20% - 25% Ti, 5% - 8% C, 1% - 2% Si, 1% - 2% Al, and the remaining being iron. To obtain ferrotitanium with a lower carbon content, silica can be added to the charge. For example, if the charge composition is 47% titanium ore (TiO₂ 51.5%), 28 . 5% силициев диоксид и 24 . 5% кокс чипс, среден - въглероден феротитан с 29% - 30% ti, 17% - 20% si, и 1,8% - 2% c могат да бъдат пушени. Увеличаването на съотношението на силициев диоксид в заряда може да доведе до ниско съдържание на въглерод и висок силиконов феротитан с около 30% Si и 0,1% - 0.3% C. Ако към заряда се добави Bauxite.
