Abstract
A device for the removal of a solidified mineral melt, termed flash, from the discharge end of a spout (3) of a transport channel (1) that is used to carry liquid mineral melt (2) to a mineral wool fiber producing unit (4). The device has a finger (9) made of a heat resistant material which is mounted to be quickly moved by a motor (10, 11) past and through liquid mineral melt (5) below and adjacent the spout (3) on the melt channel (1) in order to scrape off existing flash material from the discharge end of the melt channel (1). The device optionally may have a thermosensor, that emits an alarm signal, in case the temperature of the mineral melt at any point falls below a predetermined temperature, and/or a sensor designed to immediatley actuate the flash removal finger (9) as soon as a tendency to flash formation appears.
