Slag foaming suppression and sediment-free deregulation using sintered secondary electrostatic dust dust

摘要

The present invention relates to deregulation used in the treatment of demineralization of molten iron in a blast furnace, wherein dregs are added by adding a sintered secondary dust collector to the iron powder in an appropriate range to inhibit slag foaming and simultaneously calm It aims to provide deregulation. In order to accomplish the above object, the present invention provides a method for producing a sintered iron alloy, which comprises 70 to 90 wt% of a iron oxide powder containing 60 wt% or more of T.Fe and a sintered secondary Electric dust collecting dust: 10-30% by weight, which is a sintered secondary dust collecting dust, and a true dirt dregulation.
