Influence of characteristics of the melted basalt on the process of formation of fibers

In any production of products based on mineral fibers, one of the main types of equipment included in the line for the production of fiber products is installations for forming a basalt carpet or the so-called fiberizing chambers. The quality of finished products depends on their perfection. Currently, there are several widely used in industry methods for producing mineral fibers from the melt, which determine the various types and designs of hibernation chambers. In all chambers, the formation of mineral wool carpet occurs under the influence of hydrodynamic forces. Therefore, the study of such hydrodynamic characteristics as the rate of fall of individual fibers and clumps of these fibers and the hydrodynamic resistance of the carpet is of paramount importance in the design of new and reconstruction of old chambers. In this paper, we study the relationship between the strain rate and the viscosity coefficient of basaltic melt during fiber formation using a blown head developed by the authors...
