| 简介 |
(57) The invention relates to the production of continuous mineral fibres from earth material, glass and glass-containing materials. The inventive method for producing mineral fibres consists in forming an area for sampling a melt in a feeder where the melt has a density ranging from 2.7 to 3.8 g/cm. The ratio between the height of the melt in a furnace and the heigh of the area for sampling the melt ranges from 1.4 to 50.0. The ratio between the surface area of the melt in the furnace and the surface area of a projection of the area for sampling the melt on a horizontal plane ranges from 10 to 6000. The application of said conditions and operation modes makes it possible to significantly reduce the breakage rate of fibres during drawing and to increase the output. |
