| 摘要 |
<p>The present invention proposes a method for producing mineral fibers, wherein a first mineral molten material (8) is supplied to a first spinner (2) having a multiplicity of orifices (6) provided in its peripheral wall (4), is centrifuged thereby and subjected to an attenuating effect of a hot gas flow (12) generated by an external annular burner (10). A second mineral molten material (18) is applied from the outside onto the external surface (20) of the peripheral wall (4) of the first spinner (2) such that bicomponent fibers (14) made up of both molten materials can be produced. The present invention furthermore provides a device for fiberising mineral molten materials in order to produce mineral fiber products by means of a first spinner (2), an annular external burner (10) arranged coaxially with and preferably above the spinner (2), and a means (16) for applying a second mineral molten material (18) onto the external surface (20) of the peripheral wall (4) of the spinner (2). <IMAGE></p> |
