Silicon carbide is an inorganic substance, which is made of quartz sand, petroleum coke), sawdust and other raw materials through high-temperature smelting in a resistance furnace. It is also called diamond sand or refractory sand. So what are the production processes of silicon carbide? Today, the editor will introduce you to the production process of silicon carbide.
Silicon carbide production process:
1. Raw material crushing: Use a hammer crusher to crush petroleum coke to the particle size required by the process.
2. Batching and mixing: Batching and mixing are the process of weighing and mixing according to the prescribed formula. This project uses a platform for batching and a concrete mixer for mixing. Petroleum coke and quartz sand are batched and mixed according to the process requirements.
3. Electric furnace preparation: Electric furnace preparation is to re-finish and tidy up the furnace used last time so that it can be put into use again. The work content includes cleaning the furnace bottom material, trimming the electrode, cleaning and repairing the furnace wall, removing the force, 1 gear, and checking and eliminating other defects of the furnace.
4. Furnace loading: Furnace loading is to fill the furnace with reaction materials, insulation materials, and furnace core materials according to the specified furnace charge type, location, and size, and build the side walls of the smelting furnace with insulation and material holding functions.
5. Power supply smelting: Power can be supplied after the smelting furnace is connected to the transformer. 15 minutes after the power supply starts, an open flame is thrown to ignite CO, and the smelting process lasts for 170 hours.
6. Cooling: After the smelting furnace is stopped, it is naturally cooled, and then the furnace is removed (the furnace wall is removed and the spent material is removed), and natural cooling continues.
7. Furnace classification: Furnace classification is the process of removing crystal blocks and graphite from the furnace and separating first-grade products, second-grade products, graphite, etc. The furnace classification of this project adopts the out-of-furnace classification method, manually splitting the crystal tube, and transporting the block-shaped crystal tube to the classification field for manual classification.
