There are two primary methods for producing quartz rods: the continuous method and the flame fusion method (also known as the gas fusion method).
Continuous Method: In this method, quartz sand is fed from the top into a furnace, which comprises a metallic quartz crucible surrounded by electric heating elements. The quartz sand melts at high temperatures. The molten material then passes through a shaping orifice at the bottom of the crucible, producing rods, tubes, sheets, or other various specified product forms.
Flame Fusion Method: This method involves using hydrogen and oxygen to melt colorless quartz crystal. The molten material is formed into quartz glass through the melting and congealing of crystalline particles in the flame. The quartz glass is then removed from the flame through different methods and processed into quartz rods of the desired shape.
Halbleiterindustrie
In the semiconductor manufacturing process, quartz slotted rods are used for machining critical components such as wafers. They ensure the precision and quality of the products through precise slotting processes.
Optical Instrument Manufacturing
Quartz slotted rods are also widely used in the manufacturing of optical instruments, for applications like creating slots in lenses and prisms to meet the needs of high-precision optical systems.
Ceramics Industry
In the shaping and sintering of ceramics, quartz slotted rods are used for creating slots with specific shapes or structures, enhancing the quality and yield of ceramic products.
Andere industrielle Anwendungen
The structure of a quartz stirring rod generally includes the rod body, head, and connecting rod. Heads are designed in various shapes, such as disks or cones, to meet different stirring needs. Connecting rods are typically equipped with adjustment knobs for easy adjustment of the stirring rod length.
Anwendungsszenario
The slotting process involves several steps: First, a quartz round rod is shaped into a square rod. Then, the ends of the square rod are cut, and the flatness, length, and perpendicularity of the square rod are inspected. Subsequently, the square rod is embedded into a graphite plate with an equal number of parallel “V”-shaped grooves on its upper surface. Liquid wax is then poured to secure the square rod to the “V”-shaped grooves. Finally, the liquid wax is cooled with water to solidify, completing the fixation of the square rod.
The slotting apparatus comprises a three-axis CNC machine tool with a graphite plate on its platform. The graphite plate features several parallel “V”-shaped grooves on its upper surface. This design helps improve the positioning and fixation of the quartz square rods, enhancing slotting precision.
Using quartz slotted rods offers multiple advantages, including improving the efficiency of slotting multiple square rods simultaneously, ensuring post-slotting precision, reducing damage to square rods during the slotting process, and facilitating easy removal of the slotted square rods.
Häufig gestellte Fragen
Quarzglas ist ein hartes und sprödes Material mit ausgezeichneten physikalischen und chemischen Eigenschaften, extrem hoher mechanischer Härte, guter elektrischer Isolierung, hoher Temperatur- und Korrosionsbeständigkeit, geringer und stabiler Verzögerungsleistung, guter Lichtdurchlässigkeit usw. Es findet breite Anwendung in der Halbleiterindustrie, Optik, Elektrizität, Chemie, Luft- und Raumfahrt, Automobilindustrie und anderen Bereichen. Harte und spröde Werkstoffe sind schwer zu bearbeiten, und in vielen Bereichen werden dringend Schneidverfahren mit geringem Kanteneinbruch, geringem Materialverlust, geringer Querschnittsrauheit und einem großen Schnittdickenbereich benötigt. Das traditionelle Schneidverfahren für Quarzglas ist das mechanische Schneiden, d. h. das Scheibenschneiden. Zu den nicht-traditionellen Schneidverfahren gehören Wasserstrahlschneiden, elektrochemisches Drahterodieren, kontinuierliches Laserschneiden usw. Das mechanische Schneiden ist kostengünstig, aber der Kontakt zwischen der Scheibe und dem Material verursacht einen hohen Werkzeugverschleiß, und das Material wird leicht durch das Werkzeug verschmutzt. Quarzglas neigt zu Kanteneinbrüchen, Mikrorissen und Eigenspannungen, was die Festigkeit und Leistung des Materials beeinträchtigt! Das Schneiden von Kurven ist schwierig und erfordert Nachbearbeitungen wie Schleifen und Polieren. Das Laserschneiden kommt nicht direkt mit dem Material in Berührung, hat keine Kontaktspannungen und kann komplexe Kurvenschnitte durchführen. Der Pikosekundenlaser hat die Vorteile eines kleinen Punktdurchmessers, einer hohen Präzision, einer kurzen Einwirkungszeit auf das Material und eines kleinen Einwirkungsbereichs und eignet sich für die Bearbeitung von harten und spröden Materialien.
