摘要： An installation (100) for processing a metallurgical melt, in particular blast furnace slag, comprises at least one granulation unit (110; 120), which produces slurry of granulates and water, and a main dynamic dewatehng unit (130) connected downstream the granulation unit. The main dewatering unit (130) comprises a mobile component, in particular a rotary dewatering drum (132), for separating slurry into granulatesand water. According to the invention, the installation includes: - a slurry overflow (150) arranged upstream of or at the inlet of the main dewatering unit (130) and upstream of the water outlet (142), from which water is recovered from the main dewatering unit (130), this overflow being configured for draining slurry in excess of the unit's dewatering capacity; - a secondary dewatering unit (160) having an inlet (162) connected for receiving excess slurry from the overflow, a first outlet (164) for returning a secondary dewatered fraction to the main dewatering unit and a second outlet (166) for recovering water. The installation is configured to drain excess slurry so as to preclude excess slurry from reaching the water outlet (142) and to separate drained excess slurry into a secondary dewatered fraction returned to the main dewatering unit (130) and into a secondary water fraction recovered without passing through the main dynamic dewatering unit (130). A corresponding method of processing molten material, in particular for granulating blast furnace slag, is also proposed.

摘要： The present invention proposes a metallurgical granulation and dewatering apparatus (10) comprising a hollow drum (12) being rotatably mounted about an axis (16), the drum (12) being formed by a drum wall (20) comprising mesh material (41). The apparatus (10) further comprises feed means (46) for feeding granulated slag into a lower region (22) of the drum (12) and onto an inner surface (32) of the drum wall (20), the lower region (22) of the drum (12) comprising a slag/water slurry; and drive means for rotating the drum (12) about the axis (16), the rotation of the drum (12) causing the slurry to be entrained from the lower region (22) of the drum (12) to an upper region (24) of the drum (12), the water being drained away through the mesh material (41). The apparatus (10) also comprises collector means (48) arranged in the drum (12) at a location below the upper region (24) of the drum (12), the collector means (48) being arranged for catching slag and conveying the slag out of the drum (12); and cleaning means for cleaning the mesh material (41), the cleaning means being arranged outside the drum (12) and comprising nozzles (44) directed onto the outer surface (42) of the mesh material (41). According to an important aspect of the invention, the mesh material (41) is flexible metal grid and the nozzles (44) of the cleaning means are high-pressure water nozzles (44) for directing high-pressure water jets onto the outer surface (42) of the flexible metal grid (41); wherein the flexible metal grid (41) is configured and arranged so as to be able to bulge inwardly when subjected to water from the high-pressure water nozzles (44).

摘要： The invention relates to a method for operating a blast furnace plant (1) that comprises a blast furnace (10), at least one material hopper (20) for charging raw materials to the blast furnace (10), having a upper seal valve (21) and a lower seal valve (22), and at least one hot stove (30) that produces hot blast for the blast furnace (10), the method comprising at least one charging cycle with the following steps: - opening the upper seal valve (21), - introducing raw materials into the material hopper (20), - closing the upper seal valve (21), - pressure equalization of the material hopper with blast furnace top pressure, and - opening the lower seal valve (22) to discharge raw materials into the blast furnace (10). In order to provide a cost-effective way to minimize the explosion danger during operation of a top charging system, the invention provides that an offgas from the at least one hot stove (30) is transferred by a transfer system (40) to the at least one material hopper (20) and, before the lower seal valve (22) is opened, the offgas is injected into the material hopper (20).
