The nomenclature of fibrous heat insulation materials from basic rocks of volcanic origin is described. For basalt super thin fibers (BSTF), the production technology is described. The factors negatively influencing the engineering-and-economical performance of the duplex technology of production of the BSTF are analyzed. The engineering-and-economical performance of innovative enterprises for the production of basalt heat insulation and measures for its use in construction are given.展开更多

The conditions of formation of the layer and the intensity of heat transfer are determined. A self-similar analysis using the symmetry method was used. A system of ordinary differential equations in self-similar form is obtained. The fluid flow and heat transfer of molten basalt at a laminar steady-state flow in the feeder furnaces are numerically researched. The term “protective layer” on the interface “basalt melt-lining” is introduced. The dependences for the calculation of dimensionless shear stresses and the Nusselt number on the lining surface are obtained. The conditions of rational organization of the technological process of basalt melt feeding in the furnace feeder are formulated.展开更多
