Introduction to the production process of emery

Emery is a kind of artificially synthesized silicon carbide, which has good thermal conductivity, stability and wear resistance, so it is widely used in metallurgy, building materials, ceramics and steel industries. How much do you know about its production process? Here is a detailed summary for you:
⑴, raw material crushing
Hammer crusher is used to crush petroleum coke to the particle size required by the process.
⑵, ingredients and mixing
Batching and mixing is the process of weighing and mixing according to the prescribed formula. The platform is used for batching, and the concrete mixer is used for mixing. The batching and mixing operations of petroleum coke and quartz sand are carried out according to the process requirements.
⑶, silicon carbide electric furnace preparation
Electric furnace preparation is to refurbish and reorganize the furnace that was used last time, so as to put it into use again. The work content includes cleaning the bottom material of the furnace, repairing the electrodes, cleaning and repairing the furnace wall, removing the loading force and the first gear, checking and eliminating other defects of the furnace.
⑷, Furnace loading
Furnace loading is to fill the furnace with reaction material, insulation material and furnace core material according to the specified furnace material category, location and size, and build the melting furnace side wall with the functions of heat preservation and material storage.
⑸, power transmission smelting silicon carbide
After the smelting furnace is connected to the transformer, electricity can be transmitted. 15 minutes after the start of power transmission, an open flame is thrown to ignite CO, and the smelting process lasts for 170 hours.
⑹, cooling
After the corundum smelting furnace is shut down, it is naturally cooled, and then the griddle is carried out (unloading the furnace wall, and the exhausted material is removed), and the natural cooling is continued.
⑺, out of the oven classification
The grading of corundum out of the furnace is the process of removing the crystal block and graphite from the furnace, and separating the first-grade product, second-grade product, graphite and other materials. The out-of-furnace classification method is adopted for the grading of corundum. The crystallization cylinder is manually split, and the blocky crystallization cylinder is transported to the grading field for manual grading.
