Platinum alloy crucible for drawing glass fibers and manufacturing method of platinum alloy crucible

Abstract

The invention discloses a platinum alloy crucible for drawing glass fibers and a manufacturing method of the platinum alloy crucible. A heating plate is located in a crucible shell and located below atop cover. The top cover is arranged on the upper end surface of the crucible shell, and the connecting edge of the top cover is fixedly connected with the flanging on the heating plate. A feeding pipe is fixed on a through hole in the geometric center of the top cover. A filter screen is fixed at the lower end in the crucible shell. A bushing plate is positioned at the lower end outside the crucible shell; bushing plate side baffles are welded to the two sides of the bushing plate. Two plate-shaped connecting electrodes are symmetrically welded on the outer surface of the crucible shell. A discharge spout is arranged on a bottom plate of the bushing plate. The V-shaped platinum alloy heating plate with the thickness of 0.4 mm is used, the heating capacity inside the platinum alloy crucible is enhanced, the temperature inside the platinum alloy crucible can be helped to be increased, a glass batch mixture can be directly molten to be used for a glass fiber drawing test, and compared with the prior art, the test period is greatly shortened, and the test cost is reduced.

Description

technical field [0001] The invention relates to the field of platinum material production, in particular to a platinum alloy crucible for wire drawing of glass batch materials with a low number of pores Background technique [0002] For a long time, for a basic glass with a new composition, to test whether it can be used for glass fiber drawing and to test the basic performance of glass fiber, it is first necessary to mix the raw materials into glass batches according to the composition of the glass design, and then use The alumina crucible is melted into molten glass at high temperature, then water-cooled and quenched, and then added to a conventional glass fiber drawing crucible for wire drawing test. [0003] When using conventional platinum alloy crucibles for drawing glass fibers, it is necessary to use other heating devices to pre-melt the glass batch materials in advance to make the basic glass for drawing. The production process is too long, which increases the user'...
