Industrial Experiment of Producing Titanium White by Acid Dissolved Titanium Slag
-
摘要: 基于实验室所确定的酸溶性钛渣制取钛白的最佳工艺参数,在年产2 000 t的钛白生产线上进行了工业试验,钛渣酸解率达到92.56%,水解率大于95%,成品合格率为100%,一级品率为75%。从试验结果来看,工艺指标和产品指标达到了厂家要求,多数工序的生产能力较采用钛精矿有了较大的提高。据此,攀枝花钛精矿冶炼的酸溶性钛渣制取钛白的生产工艺已可实现产业化。Abstract: Based on the optimal technical parameters from laboratory experiment,the industrial experiment was carried out on the 2 000 t/a titanium white production plant by acid dissolved titanium slag.The digestion ratio is 92.56%,the hydrolysis ratio is more than 95%,the ratio of up to grade product is 100%,and the ratio of high grade is 75%.The results met the manufacturer's claimed technical requirements and quality level.The production capacity of titanium white by acid dissolved titanium slag is increased compared with use titanium concentrate.On these grounds,the technology of producing titanium white by acid dissolved titanium slag could be put into industrial operation.
