Experiment research on preparation pigment type magnetic iron oxide powder utilizing magnetic separated slag
This per systematically studies the influence of roasting temperature and time to the composition and performance of magnetic iron powder,with magnetic separated converter slag as raw material,and low-temperature roasting-magnetic separation craft is also used with analyzing methods of chemical,XRD,tinting strength and so on.The investigation reveals that:pigment type iron powder with high tinting strength and coveting power can be prepared with magnetic separated convener slag.Iron content and tinting strength of the iron powder rise with reaction temperature,while the covering power tends to decrease.Tinting strength of the iron powder tends to rise with extending of reaction time,while covering power rises in the first and reduces afterward,with highest coveting power of 56g·m-2 at reaction time of 30min.
