The ceramic fiberglass production line uses ceramic crucibles as drawing plates, which are fundamentally different from platinum crucible drawing wire and tank furnace drawing wire. But for ordinary people who are not very familiar with the glass fiber industry, the ceramic crucible drawing production line and the platinum crucible drawing production line do have some "similarities", especially in the production of ceramic crucible drawing production line. It is difficult to distinguish between clay crucible leak plates and platinum alloy leak plates at high temperatures.

How to quickly distinguish between clay crucible drawing production line and platinum crucible drawing production line, can be quickly screened from the following aspects:

One is to look at the installation design and supporting facilities of the leaking plate at the bottom of the drawing. The crucible drawing production line uses platinum alloy leak plates instead of platinum. Due to its long service life, the leaky brick will be equipped with auxiliary facilities such as water cooling pipes at the bottom of the leaky brick. The clay crucible leakage plate used in the ceramic crucible drawing production line has a service life of about one day and needs to be replaced frequently. Therefore, the installation of clay crucible leakage plate is convenient, and there is no need for auxiliary facilities such as water cooling pipes at the bottom of the leakage plate.

The second is to examine the structure of the furnace. The drawing furnace of the platinum crucible drawing production line is generally made of refractory materials and shaped like a cube. During production, glass ball raw materials are added to the furnace for melting, homogenization, and drawing. The clay crucible drawing production line has a relatively simple furnace, usually consisting of refractory bricks or clay bricks stacked into a molten pool, with an open top for easy addition of raw materials such as broken glass, and a clear visible high-temperature melt at the bottom.

Thirdly, it depends on the use of raw materials. Replace the platinum crucible drawing production line with glass balls as the production material. Clay crucible wire drawing production lines often use waste broken glass as raw material, and factories are generally equipped with waste glass cleaning equipment. Of course, there are also glass ball clay crucible production lines, but if the raw material used in the production line is broken glass, then it must be a clay crucible drawing production line.

The production and use of clay glass fiber will bring many safety, environmental and social issues. To this end, we must resolutely crack down on and completely eliminate the outdated production capacity of clay crucible wire drawing, laying a solid foundation for the high-quality development of industrial transformation.
