Method and apparatus for neutralising hot inclusions in a web of mineral/glass wool

摘要

The production of mineral wool takes place by melting stones, with the melt being supplied to a defibration unit. During this production process hot inclusions which are detrimental to further processing and to the final product may get into the mineral wool. To provide a method suitable for producing a homogeneous web of mineral wool free from influences by hot inclusions, the position of the hot inclusions are localized by a sensor. Position measuring data is used for controlling the nozzle system which acts upon the hot inclusions.
