ABSTRACT:
The only methods hitherto available for the production of mineral wool from materials such as basalt either utilize a stationary nozzle (blast drawing method) or external centrifuging whereby unsatisfactory yield and/or a not entirely satisfactory fiber quality, particularly with regard to a high content of unfiberized components, are achieved. By way of the invention, application of a fiberization method is suggested which, in spite of a high fluidity of the molten mineral material such as basalt, arrives at high quality fibers with a low bead proportion at good yield. This is made possible by selection of specific materials and their fiberization in specific conditions. Whereas fiberization of these fluid materials is carried out in external centrifuging at viscosities of a few tens of poises, fiberization by internal centrifuging at viscosities of more than 100 poises is required, according to the: invention, in order to achieve a mineral wool for insulation purposes with a low bead content.
