Calcium aluminate cement raw material taking ferrotitanium slag as main material and preparation method of calcium aluminate cement raw material
The invention discloses a calcium aluminate cement raw material taking ferrotitanium slag as a main material and a preparation method of the calcium aluminate cement raw material. The calcium aluminate cement raw material comprises Al2O3, TiO2, CaO, MgO, Fe2O3 and SiO2 according to a certain component proportion. According to the method, when production deslagging is carried out in the ferrotitanium alloy smelting process, molten ferrotitanium slag is directly discharged into an adjacent electric furnace; quick lime accounting for 25-40 wt% of the amount of the ferrotitanium slag is added, the electric furnace is heated to a certain temperature and subjected to heat preservation, and the quick lime and the ferrotitanium slag fully react; and blowing out the ferrotitanium slag in a molten state, cooling, and crushing into powder, thereby obtaining the calcium aluminate cement raw material taking the ferrotitanium slag as the main material. The calcium aluminate cement raw material and the preparation method thereof are energy-saving, environment-friendly, low in cost and stable in component, have the advantages of high bonding strength, low heat generation and the like, can replace part of pure calcium aluminate cement in a refractory castable system, are suitable for being used as a refractory raw material, and are simple in preparation process.
本发明公开了一种以钛铁渣为主料的铝酸钙水泥原料及其制备方法，本铝酸钙水泥原料包括一定组分配比的Al2O3、TiO2、CaO、MgO、Fe2O3和SiO2。本方法在钛铁合金冶炼过程进行生产排渣时，将熔融状钛铁渣直接排放到设于邻近的电炉中；根据钛铁渣渣量外加入渣量的25～40wt%生石灰，电炉加热至一定温度并保温，生石灰与钛铁渣充分反应；将处于熔融状态的钛铁渣吹出，冷却后破碎成粉料，即得到以钛铁渣为主料的铝酸钙水泥原料。本铝酸钙水泥原料及其制备方法节能环保、成本低廉，成分稳定，具有结合强度高、发热低等优点，可以在耐火浇注料体系中替代部分纯铝酸钙水泥，适合于作为耐火原料使用，且制备工艺简单。
