在新窑建成或旧窑进行大修后，烤窑工作至关重要，以便于放料生产。理想情况下，我们可以考虑使用其他热源进行烤窑操作，但如果必须使用硅碳棒，那么建议优先选择旧的硅碳棒。正如我们所知，在高温环境中，水蒸汽对硅碳棒是不利的，而新建的料道往往含有大量水分。此外，硅碳棒可能会长期处于高功率状态，并且表面温度较高。不论是用旧的还是新的硅碳棒进行烤窑，都需要在开始送电时将控制系统设置为“手动”模式，然后缓慢调整加到棒上的电压，使其不超过额定电压的一半，以此预热一段时间。一旦电压和电流稳定后，再逐渐增加电压。当需要加速升温时，可以通过火焰枪辅助加热，但必须确保火焰不会直接射向硅碴棒，以免导致氧化。
carbonized silicon, also known as black carbonized silicon and green carbonized silicon, the latter with higher purity, widely used in the abrasive industry and electrical industry. The production of electric heating elements using silicon carbide rods takes advantage of the properties of carbonized silicon, which is conductive, heat-conductive, and stable in nature with a long service life. Silicon carbide rods do not react with any acids. However, at around 1300 degrees Celsius, they can react with alkalies and alkaline oxides.
Silicon carbide rods have some antioxidant properties. When the rod body temperature reaches 800 degrees Celsius, surface oxidation begins to occur. As the temperature continues to rise above 1600 degrees Celsius or more than its melting point of protective layer SiO2 will be broken or peeled off causing further oxidation of the rod body leading to continuous use that results in generating a protective film on their surface thus prolonging their usage lifespan.
Therefore it is recommended that these components should be continuously used without exceeding high temperatures within reasonable limits by designing appropriate parameters for electric furnaces and silicone carbide rods correctly ensuring extended usage while maintaining optimal conditions for proper operation
