摘要

利用扫描电镜对冷轧钛带卷退火后黑点进行了分析,分析表明:冷轧钛带卷黑点主要是由于,轧制时乳化液中含有固体小颗粒残留在卷材表面压坑处,脱脂时未脱干净退火后形成。针对性制定了控制措施,采用控制措施后冷轧带卷退火后黑点比率显著降低。
        The occurrence of black spots of cold-rolled titanium coil was analyzed by scanning electron microscope. The results showed that the solid particles in the emulsion remained in the pits of the surface of titanium coil while rolling, which hadn't been eliminated by degreasing, and ofcer being annealed, the porticles caused the black spots of titanium coil after annealing. The ratio of black spots of cold-rolled titanium coil were significantly reduced after taking control measures.
