    A flow block and bushing assembly employing an orifice plate having a perforated drawing area with a planar undersurface against which bulk gas flow is directed for cooling and fiber attenuation purposes. The flow block is comprised of an interior layer of highly glass corrosion resistant material, such as zircon, and an exterior layer of highly thermal shock-resistant material. A flow passage extends through both of said layers and is lined with platinum foil. The bushing assembly is removably secured beneath the flow block and comprises a body of refractory material having a flow chamber extending therethrough in alignment with the flow passage. The flow chamber is lined with a platinum foil lining and the orifice plate is joined to the lining and extends over the lower end of the chamber. The orifice plate is reinforced by ribs integrally joined to and extending across the upper surface of its perforated drawing area and a perforated reinforcing plate is integrally joined to the ribs in spaced parallel relationship to the orifice plate. Electrodes are joined to the orifice plate to either side of the drawing area whereby electrical current may be passed through the orifice and reinforcing plates and flow chamber walls to effect the resistance heating thereof. Bulk gas flow is provided by a nozzle having a plurality of individual inlet conduits communicating with a common elongate discharge passage. An adjustable manifold communicates with the inlet conduits of the nozzle to provide for the selective supply of gas thereto and the nozzle is adjustably mounted so that its angular orientation relative to the undersurface of the drawing area may be varied.

    00 The invention relates to the building materials industry, in particular to the equipment of glass fiber factories. The closest to the proposed technical essence and the achieved result is a device for drawing fiberglass, including refractory bars with a channel and a working chamber with a flat perforated plate. The disadvantage of the device is low productivity, since the perforated plate is not. caused by heat and pressure of the feeder glass melt, which causes deformation of the perforated plate. The purpose of the invention is to increase productivity. This goal is achieved by the fact that the device for drawing Glass Fiber, including refractory bars with a channel and a working chamber with a flat perforated plate, is provided with a reflective sheet installed with a gap above the perforated plate having a perforation in the center, and the channel and chamber made with a coating connected to a perforated plate. In this case, the working chamber is made expanding to the perforated plate. FIG. 1 shows a device, an overall view, a longitudinal section; in fig. 2 the same, a cross-section ;, in FIG. 3, refractory bars and a working chamber, a longitudinal section; 4, the same cross section; on fig.Z the same, top view; in fig. 6 - refractory bars and a working chamber, embodiment, longitudinal incision. . The device consists of refractory bars, the inner layer 1, made of heat resistant and glass resistant material, such as zirconium, and the outer layer 2, made of a material that has high resistance to thermal shock, such as mullite. Channel 3 for the passage of glass melt is lined with tin foil 4. The foil lining completely covers channel 3 and forms horizontal sections on the refractory bars x, upper section 5 and lower section b (FIG. 3). The platinum dressing protects the channel from erosion and cracking resulting from the passage of hot glass through it, and is practical from an economic point of view due to the relatively small size of the channel. The presence of a lining allows the use of a material having a high resistance to thermal shock, such as a multiplier, so this layer is completely protected from direct contact with pacn iaaen glass. The small size of the channel 3 provides a rapid flow of liquid glass. Faster flow eliminates the possibility of stagnation or slow movement of glass at which growth may occur to the points. In addition, the glass is thermally more uniform in comparison with the glass flowing through a relatively large hole. FIG. 3 shows a variant of the proposed device. The inner layer 1 of the refractory bars forms a larger channel for entering the glass mass than the outer layer 2 of the refractory bars, and only the Channel formed by the outer layer of the 2. refractory bars is covered with platinum foil. The term platinum is understood to mean all alloys of platinum. The production chamber 7 is removably attached to the lower surface of the outer layer 2 of the refractory bars. Fastening is performed using a frame containing the angles 8, which are engaged in adhesion with the sides and the bottom surface of the processing chamber in order to maintain the chamber in the centered position relative to channel 3. The inner surface of the working chamber 7 is lined with aluminum foil coating 9 and the flange 10 attached to the top end of the cover and secured around the open top end of the chamber. When the working chamber is in place, the flange 10 is hermetic; superimposed on the outer part of the lower portion 6 of the cladding of platinum foil. The production chamber 7 is made with a flat perforated plastid 11 with spinnerets that do not protrude from it. The perforated plate 11 has a perforation in the center and is made with non-perforated settling zones 12 on both sides of the drawing area. . The perforated plate is reinforced by the use of a 13 pack-type design. | Vacuum pads for eggs. In addition, the working chamber is provided with a baffle plate 14 mounted across the entrance of the chamber at a distance from the lower end of the channel 3. The reflective plate is held in place by attaching it to the sides of the cover 9 of the working chamber 7 and has a pointed perforated structure. By virtue of the sharp construction, the reflective plate tends to deflect liquid glass entering the growth chamber. In this way, the reflective plate reduces the force, with the liquid glass entering the chamber falling onto the ground-breaking structure 13, and deflects the particles, for example, fragments of refractory materials or crystals into the collection zones. The extraction is terminated by means of a heat exchange pipe 15. This pipeline is of conventional construction and is used to prevent the steel from penetrating the flange and bottom of the lining of the refractory bars. The glass (and 2) is thinned in the fiber by | <1 pulling it through a perforated plate. The steel fibers 16 are drawn through the device 17 for applying an appraising composition, from where they enter the collecting roller 18 and then onto the winding mechanism 19. During the drawing process, the bulk gas flow is directed upwards onto the flat surface of the perforated plate with the spinneremes scrap 2p. The gas is used for cooling and. matine fiber. The gas is supplied to the nozzle 20 through the means of the pipeline 21. The proposed construction facilitates the removal of the working chamber during the service. Removing the camera does not present any problem, since the area of glass to be destroyed is relatively small and not one of the parts of the chamber is included in the channel. The parameters of the various elements used in the invention may differ significantly. Examples of a working chamber giving both working and physical characteristics are given below. / Construction / chambers with 795 holes with dies A 90% platinum-10% Alloy type rhodium.
