    The crucible is the most important piece of equipment in the wire drawing process.

    Its function is to heat and melt glass balls or cullet as a container for molten glass. The power supply passes through the transformer and saturation reactor or thyristor, so that the crucible reaches the required current and voltage and heats up to melt the glass, and the glass liquid flows out of the leakage hole, which is drawn into glass fiber by the wire drawing machine. The brushed crucibles used in China include platinum crucibles, substitute platinum crucibles, clay crucibles and other forms.

    In addition, there are also pond kilns where wire drawing is carried out directly from the powder molten glass.

    a) Platinum crucibles.

    Platinum crucibles are made of platinum rhodium alloy. In order to improve its hardness, mechanical strength or the stiffness of the crucible, it is generally mixed with 7%-10% rhodium, and more than 10% alloy is brittle. The mechanical strength of platinum alloys doped with 10% rhodium is 3 times that of the original.

    Platinum rhodium alloys have a high melting point and can withstand the high temperatures of molten glass very well. It is an excellent resistive heating material, which can melt the molten glass and rise to a temperature suitable for wire drawing after applying an electric current. Platinum alloys have excellent resistance to oxidation at high temperatures and chemicals.

    The platinum crucible is mainly composed of the top cover, the leakage plate, the pot wall, the electrode and other main parts.

    b) Substitute platinum crucibles.

    The platinum-substituted crucible has only a leakage plate and an electrode connected to it, which is made of platinum rhodium alloy, while the pot body and its related accessories are made of refractory masonry. The molten glass in the crucible is heated by the molten glass itself as a resistive energized heat, or by the platinum alloy heating element placed in the pot to heat the glass, or the resistive heating element (plus silicon carbon rod) can be used to heat the glass by radiation on the liquid glass surface to make the molten glass reach the required temperature.

    Use a platinum crucible or use a substitute platinum crucible.

    Scrap bricks need to be tested for metal minerals to determine their grade in order to determine their value.

    No, if there is, it won't be sold to you cheaply, and others don't think of it.

    Is it a running pile? It can be controlled by adjusting the feeding method, temperature system, flame angle, etc.

    Platinum has a small wetting angle on glass, which is suitable for filament molding.

    Platinum has high temperature creep resistance (generally doped with rhodium powder, higher strength), stable high temperature performance, and low volatilization.

    First of all, the upstairs, don't copy me word for word, mine is scribbled, not so standard

    First: the silk code will break, the general reason may be that there are miscellaneous materials in the glass (unmelted or foreign matter), and then there is the problem of leakage.

    Second, if you want to produce stable quality yarn, transformer is indispensable Third, the output problem is different, and the variety and specifications you produce are different, the output is very different, for example, there are 4000-6000 holes of the leakage plate, the output can reach more than tons per day, if the production of spinning yarn, the output is only 70 kg a day.

    First: the wire will break, the general reason may be that there are jokes about impurities in the glass (unmelted or foreign matter), and then there is the problem of leakage.

    Second, in order to produce yarn with stable quality, it is essential to touch the source and transformer.

    Third, the problem, different quality and different specifications of yarn, ** is very different, the general yarn, currently above 8000, the best in hundreds of thousands, see what you do to crack rough!
