Embodiment 1

[0032] Such as figure 1 Shown in -7, a kind of platinum-rhodium alloy leak plate provided by the present invention includes a leak plate body, and the leak plate body includes a box body 1 and a screen plate 3 arranged in the box body 1, outside the box body 1 The edge is provided with flanging 2, the bottom of the box body 1 is provided with a bottom plate 4, and the bottom of the bottom plate 4 is provided with a number of nozzles 401, and the bottom plate 4 is provided with a number of channels 402 corresponding to the positions of the nozzles 401. One side of body 1 is provided with AB thermocouple wire;

[0033] The top surface of the bottom plate 4 is provided with a plurality of diversion step grooves 403, and the length direction of the diversion step grooves 403 is perpendicular to the length direction of the box body 1, and the vertical cross-sectional shape of the diversion step grooves 403 is a right triangle, And the two right-angled sides of the right-angled tri...

Embodiment 2

[0041] Such as Figure 8As shown in -10, the present embodiment is basically the same as Embodiment 1, the only difference being that a guide edge 405 is arranged on the outside of the guide port 404, and the guide edge 405 is in a vortex shape, and the pitch of the vortex line is equal to that of the guide port. 1 / 2 of the diameter of 404, the number of turns of the spiral line is 3 turns. The vertical section of the guide edge 405 is an equilateral triangle, and the length of the side of the triangle is equal to 1 / 4 of the diameter of the guide opening 404 . The purpose of setting the guide edge 405 is to make the molten glass form a small vortex at the guide port 404 and accelerate the molten glass entering the channel 402 .

Abstract

The invention relates to the technical field of glass fiber wire drawing, in particular to a platinum-rhodium alloy bushing plate. Comprising a bushing body, the bushing body comprises a box body and a filter screen plate, a bottom plate is arranged at the bottom of the box body, a plurality of nozzles are arranged at the bottom of the bottom plate, a plurality of channels corresponding to the nozzles in position are formed in the bottom plate, and an AB thermocouple wire is arranged on one side of the box body; a plurality of diversion stepped grooves are formed in the top face of the bottom plate, the length direction of the diversion stepped grooves is perpendicular to the length direction of the box body, the vertical section of each diversion stepped groove is in a right triangle shape, the two right-angle sides of each right triangle are the long side and the short side respectively, the long sides are parallel to the ground, and the short sides are perpendicular to the ground. The bevel edge of the right triangle is defined as the groove face of the flow guide step groove, a plurality of guide openings are formed in the groove face of the flow guide step groove, and the guide openings, the channel and the nozzle are communicated. By adjusting the structure of the platinum-rhodium alloy bushing plate, the rhodium content is reduced, the same service time can be achieved, and the purpose of reducing the production cost is achieved.

Description

technical field [0001] The invention relates to the technical field of glass fiber drawing, in particular to a platinum-rhodium alloy bushing. Background technique [0002] Platinum-rhodium alloy bushing plate is one of the important equipment in the glass fiber production process. Its working principle is that the transformer lowers the voltage and increases the current, and raises the temperature of the platinum-rhodium alloy bushing plate to the same Log3 temperature of the glass to ensure that the kiln melts The molten glass successfully utilizes the platinum-rhodium alloy bushing plate, divides the molten glass into multiple glass fibers according to the number of holes in the platinum-rhodium alloy bushing plate, and then winds them into fiber filaments of different thicknesses through a wire drawing machine. The operating temperature of the platinum-rhodium alloy bushing is the same as that of the glass Log3, about 1250°C, which belongs to high-temperature operation. ...
