摘要: 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.

摘要: A process and apparatus for controlling the manufacture of mineral fibers, in particular glass fibers, by use of a fiber-drawing process using internal centrifuging in a centrifuger. The peripheral strip is pierced by a large number of outlet orifices and the radiation emitted superficially by the peripheral strip is measured in order to determine the temperature of points of the peripheral strip and the vertical coordinate of each of the points measured.

摘要: Mineral material, particularly of the basalt type, is fiberized by internal centrifuging in a spinner having a peripheral wall with a plurality of orifices. A heated gas flow attenuates into fibers the filament cones emanating from the orifices. To produce mineral wool with good fiber fineness and largely free of unfiberized particles, the length of the filament cones and the configuration of the heated gas flows generated around the spinner are adjusted so that the majority of the filament cones emanating from the spinner orifices intersects the isotherm corresponding to a viscosity of 100 poises to enter into a zone cooled down to a temperature corresponding to a viscosity of more than 100 poises. The configuration of the heated gas flow is produced by an annular external burner in conjunction with an annular external blower that produces jets of cool air. The cool air brings low-temperature isotherms in close vicinity to the peripheral wall of the spinner. This enables the tips of the filament cones to reach into a cool zone, thereby increasing the viscosity at the tip of the filament cones to avoid breakage of the filament cones to be attenuated.

摘要: A method for producing mineral wool of a material which is highly fluid at an elevated liquidus temperature in particular above 1,200.degree. C., with a viscosity of less than 5,000 poises at liquidus temperature, is proposed wherein the molten mineral material, after having destroyed all nuclei of crystallization, is supplied into a spinner (1') the peripheral wall (19) of which comprises a multiplicity of orifices with small diameters wherethrough said molten material is centrifuged to form filaments which, in a given case, are subjected to a supplementary attenuating effect of a preferably hot gas flow flowing along said peripheral wall (19) of said spinner (1') and generated by a concentric annular external burner (13). If fiberization of such a material is effected in the traditional way, a great proportion of unfiberized particles in the product will result. To avoid this, the spinner temperature in ongoing, continuous operation is maintained at a balanced value which is lower than or equal to the temperature at which the viscosity of the molten mineral material is 100 poises, and higher than the crystallization temperature in undercooled state of said material to be fiberized.
