用含铁废料制备软磁用高纯α-Fe_2O_3工艺的探讨

Study on Preparation Method of Soft Magnetism Use and High Purityα-Fe_2O_3 in Iron Scrap

通过介绍以钛白副产硫酸亚铁、工业酸洗废液、平炉红尘等为原料制备软磁用α-Fe2O3的工艺,探讨了工艺方法、工艺参数及影响因素等。

This paper get across recommended p reparating technics of soft magnetism withα-Fe 2 O 3 using by -product ferrous sulfate of TiO 2 plant,pickling waste liquid,Furnace dust,magnetite,pyrite cinder etc.for raw material and discussed the technological method,the technological parameters a nd the influential factors.
