Corundum-spinel refractory raw material with ferrotitanium slag as main material and preparation method of corundum-spinel refractory raw material
The invention discloses a corundum-spinel refractory raw material taking ferrotitanium slag as a main material and a preparation method. The refractory raw material comprises certain components of aluminum oxide, magnesium aluminate spinel and titaniferous oxide. According to the method, when slagging is carried out in the ferrotitanium alloy smelting production process, light calcined magnesia or magnesite is used as a slagging agent to replace a traditional calcium oxide slagging agent, ferrotitanium slag in a molten state is blown out, cooled and then crushed into powder, and the corundum-spinel refractory raw material with the ferrotitanium slag as the main material is obtained. The refractory raw material can be directly used as a raw material in a high-grade alumina-magnesia spinel refractory material, and the additional value of the titanium-iron slag is higher than that of the titanium-iron slag produced by the traditional lime slag former. The preparation method has the advantages of simple process, energy conservation, environmental protection, low cost, stable components, high bonding strength, low heat generation and the like.
本发明公开了一种以钛铁渣为主料的刚玉‑尖晶石质耐火原料及制备方法，本耐火原料包括一定组分的氧化铝、镁铝尖晶石和含钛氧化物。本方法在钛铁合金冶炼生产过程进行造渣时，以轻烧氧化镁或者菱镁石作为造渣剂，替代传统的氧化钙造渣剂，将处于熔融状态的钛铁渣吹出，冷却后破碎成粉料，得到以钛铁渣为主料的刚玉‑尖晶石质耐火原料。本耐火原料可以直接用于高档铝镁尖晶石质耐火材料中的原料，钛铁渣的附加值高于传统利用石灰造渣剂产生的钛铁渣。本制备方法工艺简单，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。
