PROCESS FOR PREPARING A MELT FOR PRODUCING MINERAL FIBERS AND A SHAFT FURNACE FOR MAKING THE SAME

摘要

the starting material in the form of solid mineral, undertake to the upper part of the shaft (1) furnace, heating and melting by means of at least one burner (17).melt is deleted from the dna furnace output hole (10), the slanted surface (21) of material in the furnace is fed waste material from mineral fibres.the furnace consists of a shaft (1), at the upper end of the bearing means (2) for introducing the starting material.in the lower end of the switching to the propagation and in the lateral direction for generating oblique surface (21) of column materialwhich is located at least one burner (17) towards the slanted surface (21) of material and the upper wall (7) of the extension shaft (1) are located means for introducing the waste materialof mineral fibres on the sloped surface (21) of materiu00e1lu.u0155
