Example Embodiment

[0015]Such asfigure 1As shown, the present invention provides a method for emptying residual glass in a platinum rhodium crucible, which includes the following steps:

[0016]S1, take corundum tray 1;

[0017]S2. Place a set of corundum pads 2 in the corundum tray 1; when placing the corundum pads, arrange them according to the edge of the platinum-rhodium crucible;

[0018]S3. The platinum-rhodium crucible 3 with the remaining molten glass is inverted on the corundum block 2, and the edge of the platinum-rhodium crucible 3 is matched with the corundum block, so that the corundum block supports the platinum-rhodium crucible;

[0019]S4. Put the corundum tray and the platinum-rhodium crucible as a whole into the high temperature, and keep them at 1630°C for 20 minutes, so that the residual glass liquid flows into the corundum tray 1 along the inner wall of the platinum-rhodium crucible 3.

[0020]Then take out the platinum-rhodium crucible 3 first, and then take out the corundum tray 1 containing t...

Abstract

The invention discloses a method for emptying residual molten glass in a platinum-rhodium crucible. The method comprises the following steps: S1, taking a corundum tray; S2, placing a group of corundum cushion blocks in the corundum tray; S3, inversely buckling the platinum-rhodium crucible with residual molten glass on the corundum cushion blocks, and enabling the crucible edge of the platinum-rhodium crucible to be matched with the corundum cushion blocks to enable the corundum cushion blocks to support the platinum-rhodium crucible; S4, integrally putting the corundum tray and the platinum-rhodium crucible into a high temperature, and keeping for 20 minutes at the temperature of 1630 DEG C, so that residual molten glass flows into the corundum tray; a high-temperature heating mode is adopted, so that residual molten glass naturally flows into the corundum tray, the time for removing the residual molten glass is greatly shortened, and the experiment efficiency is improved; hydrofluoric acid is not used, so that environmental pollution is reduced; according to the method, no external force is applied to the platinum-rhodium crucible, damage to the platinum-rhodium crucible is reduced, and the service life of the platinum-rhodium crucible is prolonged.

Description

technical field [0001] The invention relates to the technical field of glass melting experiment processing equipment, in particular to a method for hollowing out residual glass liquid in a platinum-rhodium crucible. Background technique [0002] During the glass melting experiment, the batch materials are put into the platinum-rhodium crucible and melted into glass. After the glass is poured into the formed platinum-rhodium crucible, there will be residual glass liquid in the platinum-rhodium crucible. If the residual glass liquid is not cleaned up, it will affect the next time. Glass experiment. [0003] At present, two methods are generally used to clean the platinum-rhodium crucible: 1. Put the platinum-rhodium crucible into hydrofluoric acid by hydrofluoric acid soaking method to make the residual glass liquid inside the platinum-rhodium crucible fall off. This method takes a long time and is caused by hydrofluoric acid. Environmental pollution, 2. Use the external forc...
