method for operating a sintering plant and method for operating a blast furnace in a blast furnace

摘要

the invention relates to a method for operating a sintering installation, with a sintering mixture being burned in a sintering machine (10), the method comprising the steps of: a) crushing sintered burnt below a limit superior particle size; b) examine the crushed sintering to remove fine particles and separate at least two fractions of sintering size, typically fractions of smaller, intermediate and larger size; c) store each of the at least two sinter size fractions in a respective separate storage unit (40, 42, 44). the sintering fractions examined are not re-mixed in the sintering facility, but are routed to the blast furnace facility (20?), where they are stored in the respective separate storage units (40, 42, 44). the sintering fractions examined can be stored in an intermediate way in separate units in the sintering facility, before being sent to the blast furnace.
