Silicon carbide itself is a synthetic material with a high melting point (1750-1955 K, veya 2690.33-3059.33 °F), excellent hardness (600-3800 MPa), iyi termal iletkenlik (3.8-20.7 W/m.K), and low thermal expansion (7.9-11 10^-6/K). These properties make it ideal for the high-temperature, high-stress environments where these rollers are typically used.
Silisyum Karbür Silindirlerin Üretim Süreci
SiC merdanelerinin üretimi tipik olarak üç ana adımı içerir:
Toz Üretimi
The process begins with the production of high-purity silisyum karbür tozu, genellikle silikon ve karbon öncülerinin bir kombinasyonu olan. These precursors undergo a series of chemical reactions to form fine SiC particles.
Şekillendirme
SiC tozu daha sonra bağlayıcılarla karıştırılır ve çeşitli teknikler kullanılarak istenen şekle preslenir., kuru presleme veya izostatik presleme gibi. Bu yeşil bir gövde oluşturur, hangisi sıkıştırılmış, sinterlenmemiş ürün.
sinterleme
Yeşil gövde, kontrollü bir atmosferde yüksek sıcaklıklara ısıtılır., SiC parçacıklarının birbirine bağlanmasına ve yoğun bir yapı oluşturmasına izin vermek, güçlü yapı. Bu süreç, sinterleme olarak bilinir, Nihai silisyum karbür merdane ile sonuçlanır.
Silisyum Karbür Silindirlerin Avantajları
- Yüksek Sıcaklık Dayanımı: Silicon carbide rollers can withstand extremely high temperatures, making them ideal for use in industries like glass manufacturing, seramik, and semiconductor production. The maximum service temperature of silicon carbide can reach up to 970 K (1286.33 °F).
- Excellent Thermal Conductivity: Silicon carbide’s thermal conductivity ranges from 3.8 ile 20.7 W/m.K. This high thermal conductivity allows these rollers to quickly dissipinate heat, reducing the risk of thermal damage and ensuring more uniform heating across the surface of the material being processed.

- Dimensional Stability: Silicon carbide rollers exhibit superior dimensional stability, maintaining their shape and size even under high temperatures and pressures. This ensures consistent performance and quality in manufacturing processes.
- Düşük Termal Genleşme: Silicon carbide has a relatively low coefficient of thermal expansion (7.9-11 10^-6/K), meaning it doesn’t expand or contract much with temperature changes. This stability is crucial in high-temperature applications and helps to maintain the integrity of the roller and the materials being processed.
- Uygun Maliyetli: Although the initial cost of silicon carbide rollers may be higher than traditional materials, their long lifespan, lower maintenance requirements, and improved efficiency can make them a cost-effective choice in the long run.
- Yeterlik: Silicon carbide rollers can improve the efficiency of production processes due to their high thermal conductivity and dimensional stability. Örneğin, they help ensure uniform thickness in glass production and contribute to the precision and efficiency of the silicon wafer polishing process in the semiconductor industry.
- çok yönlülük: Due to their outstanding properties, silicon carbide rollers can be used in a variety of industries and applications, from high-temperature kilns and furnaces to semiconductor production and glass manufacturing.
- Çevre dostu: Silicon carbide is an inorganic, non-toxic material. Dahası, the longevity of silicon carbide rollers reduces the need for frequent replacements, contributing to waste reduction and making them an environmentally friendly option.
