隧道窑高温炉加热棒碳化硅管陶瓷烧结U硅碳棒检重机检测物品
在新窑建成或旧窑进行大修后，烤窑工作是必须要完成的步骤，以确保料子的生产质量。在条件允许的情况下，我们应该考虑使用其他类型的热源来烤窑，如果不得不使用硅碳棒，那么建议优先使用老旧的硅碳棒。正如前面提到的，在高温环境下，水蒸汽对硅碳棒是不利的，而新建的料道中含有大量水分，而且硅碳棒可能会长期处于高功率状态，表面温度较高。不管是用新的还是老旧的硅碳棒进行烤窑，都需要在开始送电时，将控制系统设置为“手动”模式，并缓慢调节加到硅碳棒上的电压，不超过额定电压的一半，然后预热一段时间。当电压和电流稳定后，再逐渐升高电压。如果需要加速升温，可以通过火焰枪辅助加热，但必须避免让火焰直接接触到硅碳棒，以免其被氧化。
carbonized silicon, also known as carbonized silicon carbide, is a type of material that has both electrical and thermal conductivity properties. It is widely used in various industries such as refractory materials, abrasives, and electrical components due to its high purity and stability. However, it should be noted that carbonized silicon carbide can react with alkaline substances at temperatures above 1300°C.
Silicon carbide rods have good oxidation resistance. When the rod body temperature reaches 800°C, the surface begins to oxidize. As the temperature continues to rise, a layer of SiO2 forms on the surface of the rod body, which prevents further oxidation and extends the life of the rod.
However, this protective layer has a melting point above 1600°C. If the rod body temperature exceeds this value during use or maintenance operations, the protective layer may break down or peel off. This would cause further oxidation of the silicon carbide rod and reduce its lifespan.
Therefore, it is important to design electric furnaces and parameters for silicon carbide rods correctly to ensure their long-term use without overheating them too much during production processes.
