使用旋转圆柱法研究了烧成白云石在含钒钛转炉渣中的损毁速度,并结合岩相和能谱分析检验,指出炉衬损毁的两种机理:在1400℃下CaO未饱和的初渣中为表层渣化溶解,在1600℃下CaO饱和的终渣中为渗透解体.攀钢半钢终渣含有较高的Fe_nO和Al_2O_3,并具有极低粘度,这种渣向炉衬内渗透,造成耐火材料从内部熔融和解体是攀钢炉衬寿命低的主要原因,文中还提出了解决办法.
The rotating cylinder method was used to study the destruction rate of calcined dolomite in vanadium-bearing titanium converter slag. Two mechanisms of failure of lining were pointed out by combining lithofacies and energy spectrum analysis. In the initial slag with unsaturated CaO at 1400 ℃ For the surface of the slag dissolved in 1600 ° C CaO saturated final slag for infiltration disintegration.Pangang Steel semi-steel final residue contains higher Fe_nO and Al_2O_3, and has very low viscosity, this slag infiltration into the lining, resulting in fire-resistant Material from the internal melting and disintegration is the main reason for the low life of Panzhihua Furnace lining, the paper also proposed solutions.
