Função da haste de silício carbono da máquina de fusão

‌The main function of the silicon carbon rod in the melting machine is to serve as a heating element, converting electrical energy into thermal energy through the electrothermal effect, thereby heating and melting the sample. ‌

Silicon carbon rods have the following main characteristics:

‌High temperature resistance‌: Silicon carbon rods can work stably in high temperature environments, and the operating temperature can reach 1450℃‌12.
‌Oxidation resistance‌: When heated in air, silicon carbon rods show good oxidation resistance and can be used for a long time in an oxygen-containing environment‌23.
‌Corrosion resistance‌: It has good chemical stability, and acids have no effect on it, but alkali and alkaline earth metal oxides have a corrosive effect on it at high temperatures‌24.
‌Fast heating‌: The silicon carbon rod has a fast heating speed and can quickly reach the required heating temperature‌12.
‌Long life‌: The silicon carbon rod has a long service life, and its service life can be extended by increasing the density‌24.
These characteristics enable the silicon carbon rod to efficiently and stably heat and melt the sample in the melting machine, ensuring the smooth progress of the melting process
