汽车散热器使用隧道窑高温炉加热棒碳化硅管助力陶瓷烧结U硅碳棒
在新窑建成或旧窑进行大修后，烤窑工作至关重要，以便放料生产。在条件允许的情况下，建议采用其他热源进行烤窑操作。如果确实需要使用硅碳棒，建议优先使用旧的硅碳棒。正如前述，在高温下水蒸汽对硅碳棒是不利的，而新建的料道通常含有大量水分，而且硅碴棒可能会长期承受高功率工作，其表面温度较高。不论是使用旧的还是新的硅碳棒，都应将控制系统设置为“手动”模式，在开始送电时缓慢调节电压至额定值的一半，并预热一段时间。当电压和电流稳定后，再逐渐升高电压。在加速升温过程中，如果需要火焰枪辅助加热，一定要避免让火焰直接射向硅碳棒，以免其被氧化。
carbonized silicon, also known as carbonized silicon carbide, is a type of material that has been widely used in various industries. It can be divided into two types: black carbonized silicon and green carbonized silicon. The latter has a higher purity and is commonly used in the abrasive industry and electrical industry due to its ease of use.
The production of electric heating elements using silicon carbide rods takes advantage of the material's ability to conduct electricity and heat, as well as its stability and long lifespan. Silicon carbide rods are resistant to any acid reaction but can react with alkaline substances at temperatures above 1300°C. They have a certain degree of oxidation resistance, with the surface beginning to oxidize when the rod body temperature reaches 800°C. As the temperature continues to rise, a layer of SiO2 forms on the surface, which helps protect the rod from further oxidation and extends its lifespan.
However, this protective layer has a melting point that can be broken or peeled off when the rod body temperature exceeds 1600°C. This allows for continued oxidation of the rod until it generates another protective layer. Therefore, it is important not to continuously use high-temperature heating elements made from silicon carbide rods without proper maintenance or replacement.
In summary, correct usage practices are crucial for extending the life expectancy
