摘要:
The present invention concerns a bushing assembly comprising: (a) a liquid glass feeding unit arranged upstream of, and in fluid communication with, (b) a first and second tip plate assemblies (1A, 1 B) extending along a longitudinal direction, arranged side by side, and each surrounded by side walls and end walls and, the first and second tip plate assemblies being separated from one another by a stiffening rib structure (21) extending along said longitudinal direction,
characterized in that, the feeding unit comprises a glass distribution manifold (2), which defines two separate fluid communication paths to the first and second tip plate assemblies (1A, 1 B), and in that, the stiffening rib structure (21) forms an integral part of the floor of the manifold (2).

The invention relates to the technology for producing continuous mineral fibres from rocky raw material, in particular from basalt rock, from mixtures based on basalt rock, from glassy industrial and technical waste products. The production process for mineral fibres comprises forming a withdrawal region for the melt in the distributor duct such that the ratio of the height of the melt in the distributor duct to the height of the melt in the withdrawal region is in the range from 3.4 to 20.

A plurality of different structural members for reinforcing a plate-like structure, such as a bushing tip plate (T) for intended use in forming fibers from a fluid material supplied to a bushing assembly, are disclosed. Each reinforcing member (10a, 10b) includes a body having a first portion (12) for attachment to the structure and a second portion (20) having a profile with a variable height including at least one apex (A). The body may be integrally formed of a single piece of material, or two or formed from more separate pieces of material bonded or secured together. The body may be T-shaped (312, 320), L-shaped (310), or F-shaped (212, 220) in cross-section. The second portion of the body may have an inverted V-shaped profile (520), an inverted W-shaped profile (620), or an arcuate profile (420). The at least one apex may be located at the midpoint (M) or elsewhere along the length of the body.

A multi-screen mixing apparatus for installation in a fiber-forming bushing used in the manufacture of glass fibers. The multi-screen mixer attaches to the walls of the bushing, and includes a first screen having openings therein through which the glass flows and a second screen having openings through which the glass flows longitudinally spaced from the openings in the first screen such that the molten glass must flow in a non-linear path as it passes through the screens. Additional screens can be added to cause additional flow diversion to further mix the molten glass.

As recycling use of a waste matter, rock wool is produced by granulating municipal refuse incinerated ash, which cannot be used easily in the powdery form, by a granulator, thereby forming a low-cost solid raw material in the massive form; charging it with adjusting raw materials in a welting furnace; melting the resulting mixture; and fiberizing the molten.

L'invention a pour objet un dispositif de fibrage statique pour produire de la laine minérale comportant :
↪ des moyens d'amenée (30, 31) aptes à délivrer des filets de matière minérale en fusion à proximité de moyens pneumatiques d'étirage, ↪ des moyens pneumatiques détirage comportant au moins un moyen pour générer un courant gazeux chaud dit principal (5) et un moyen pour générer au moins un jet gazeux (6) dit secondaire dont la direction d'écoulement est convergente avec celle du courant gazeux principal. Ces moyens d'amenée comprennent des canaux alimentés en matière minérale en fusion débouchant sur des orifices de sortie par lesquels s'écoulent lesdits filets, notamment dans une structure de type filière, au moins une partie desdits canaux étant groupée en paires de canaux A, B alimentés respectivement en une matière A et une matière B, s'achevant en deux orifices accolés (35b, 36b) ou adjacents, ou se rejoignant en un canal commun AB (40) s'achevant en un orifice commun (41).
摘要:
The process and apparatus of the present invention enable the production of glass fiber product from scrap glass fibers. The invention includes: feeding the scrap glass fibers (14) having an average length up to around 12 inches to a glass melting tank (40) having a pool (36) of molten glass, melting the scrap glass fibers (14) without the presence of non-vitrified glass forming materials in an oxidizing environment, conditioning the melt to a formable viscosity, and forming the glass fiber from the conditioned melt where for a given glass fiber product there is a near constant pull of the melted glass from the melter (40). The rate of feeding of the scrap glass to the melter is sufficient to maintain the pool of melted glass with a level within the range of + 0.35 inch (9 mm.) over a period of eight hours. The glass melter (40) has a high length to width ratio with a finite-sided melting containment area which holds a pool of molten glass (36) that receives the scrap glass.
