Abstract
本发明涉及来自硫酸盐法的TiO2残渣用于治金工艺中或者用作耐火材料的成分的用途。其中,无需将该TiO2残渣进一步与其他物质混合就进行干燥和添加。
Description
本发明涉及来自硫酸盐法的TiO2残渣的用途。
TiO2产品的残渣(TiO2残渣)在冶金工业中的应用是已知的。DE 4419816 C1公开了一种含钛添加剂,由TiO2残渣和其他物质组成。DE 19705996 C2公开了一种含TiO2的添加剂的制备方法,是将TiO2残渣和铁或铁化合物的混合物在200-1300℃下进行热处理。但是缺点是TiO2残渣与添加剂的其他每一组分的计量和混合烦琐。
DE 19830102 C1公开了利用盐酸盐法制备TiO2时产生的含TiO2的细颗粒残渣的用途。但其缺点是按照硫酸盐法制备TiO2时,没有产生这种细颗粒状的含TiO2残渣,因此其不能用于来自硫酸盐法的TiO2残渣。
本发明的目的是克服现有技术的不足,尤其是提供一种按照硫酸盐法生产TiO2产品时TiO2残渣的简单应用。
本发明的目的是通过将硫酸盐法TiO2残渣应用于冶金工艺中或者用作为耐火材料的成分而实现的,其中TiO2残渣无需进一步与其他物质混合就进行热处理和添加。
令人惊奇地发现,由硫酸盐法获得的TiO2残渣用于治金工艺中或作为耐火材料的成分与迄今为止由TiO2残渣和其他物质的混合物具有同样的所需功效。该TiO2残渣在进行热处理时可以不进行洗涤或者进行洗涤和中和。
对TiO2残渣的热处理优选在100-1300℃下进行。TiO2残渣可以以粉末状或者有形体的形式存在(例如通过烧结、成球、压块或压制而获得)。
经热处理(干燥)的TiO2残渣优选含有下列物质作为主成分(数据按重量%给出):
TiO2 35-70
SiO2 5-40
铁化合物 2-15
MgO 1-15
CaO 0.5-15
或者,经热处理(干燥)的TiO2残渣换算成氧化物具有下列主成分(数据按重量%给出):
TiO2 20-80
SiO2 2-30
Al2O3 0-15
Fe2O3 0-15
MgO 1-15
CaO 0-15
在优选的应用中,将经热处理的TiO2残渣吹入冶炼炉例如高炉或电熔融炉或冲天炉中,从而提高了耐火炉衬的耐久性。其他的应用是将TiO2残渣用作堵口泥和耐火材料。
下面借助实施例详细说明本发明的主题。
实施例1:为用于冶炼炉中而进行的硫酸盐法TiO2残渣的处理
将100吨压滤卸料(洗选残渣)在进口温度为650℃的回转管式炉中进行处理,该压滤卸料在洗选硫酸盐法TiO2产品时产生,并具有75重量%的固含量和53重量%的TiO2(按固含量计)。获得的细颗粒产品的残余湿度为0.5重量%。该产品具有非常好的流动性(Rieselfhigkeit)并且可借助于气动输送很容易地吹入冶炼炉(这里是高炉)中。
该产品具有下列组成(按重量%计):
TiO2 53
Fe2O3 5.9
SiO2 27.8
Al2O3 6.1
MgO 2.4
CaO 4.2。
