Customized Silicon Carbide Graphite Crucible from Rongsheng Manufacturer
Silicon carbide crucibles and graphite crucibles are containers with good high-temperature resistance, which are usually more common in industrial metal smelting and casting. Compared with graphite crucibles, silicon carbide graphite crucibles are resistant to high temperatures and oxidation. Silicon carbide crucibles are larger than graphite crucibles and have a longer service life. Silicon carbide manufacturers produce silicon carbide, graphite crucibles, non-ferrous metal castings, and high-heat conduction crucibles. The size of the negative electrode material pre-carbonized crucible is 500*1200mm. Rongsheng manufacturers customize silicon carbide graphite crucibles.
Good Thermal Vibration, Corrosion Resistance, High-Temperature Resistance Silicon Carbide Crucible
Thermal conductivity: High thermal conductivity material is adopted, with dense structure, low apparent porosity, and fast thermal conductivity.
Long service life: Compared with ordinary clay graphite crucible, the service life of the same material can be increased by 2-5 times.
High Density: Using an advanced isostatic pressing molding process, the material is dense and uniform without defects.
High strength: material selection, high-pressure pressing, good high-temperature strength, scientific product shape, high pressure bearing capacity.
Corrosion resistance: Advanced material formula can effectively resist the physical and chemical effects of the melt.
Less sticky slag: There is less slag hanging on the inner wall, which greatly reduces the possibility of heat resistance and expansion of the crucible.
High-temperature resistance: the operating temperature is 400-1700°C.
Less pollution: The material design fully considers the relationship and process characteristics of the smelted metal, and contains almost or no harmful impurities.
Metal saving: Because the material contains special elements, it can effectively inhibit the oxidation of metals.
Energy saving and environmental protection: fast heat conduction can save a lot of fuel, reduce waste pollution, proper resistivity, and induction heating can significantly reduce reactive power loss.
High oxidation resistance: the advanced anti-oxidation mechanism makes the graphite in the crucible well protected.
How to Use the Silicon Carbide Crucible Correctly?
Many people do not preheat the new silicon carbide crucible when using it, which can easily cause the crucible to crack. So we must preheat the crucible before using it. So, how to preheat the crucible?
Preheating is to dehumidify the crucible. The new silicon carbide crucible can be placed next to the oil furnace for preheating 4-5 hours before use. Charcoal can also be burned in the crucible for about 4 hours before using a new silicon carbide crucible, which also dehumidifies the Lake Tana precious crucible. The temperature changes during the heating and preheating time of the new crucible furnace, and the temperature is slowly heated at 0°C-200°C for 4h. Heat slowly at 0°C-300°C for 1h. Heat slowly at 200°C-300°C for 4h. Heat slowly at 300°C-800°C for 4h. Heat slowly at 300°C-400°C for 4h. Rapid heating at 400°C-600°C for 24h. After the furnace is shut down, the preheating time of the furnace is as follows. Oil furnace and electric furnace: 0°C-300°C slow heating for 1 hour, 300°C-600°C slow heating for 4 hours, and when the temperature is above 600°C, it can be heated quickly to a certain degree.
When using a silicon carbide crucible, it must be operated in accordance with the operating procedures in order to better create more value for the silicon carbide crucible and bring more economic benefits.
