What Is Silicon Metal 3303?
Often referred to as crystalline silicon or industrial silicon, silicon metal is a grey, glossy semiconductor metal that is mostly utilized as an additive for non-ferrous alloys that are melted from quartz and coke in an electric furnace. Metallic silicon is often categorized based on the amount of iron, aluminium, and calcium it contains. Silicon metal is available in a variety of grades, including 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, and 1101.Typically, the diameter ranges from 10 to 50 mm, 50 to 100 mm, or different sizes per customer requirement.
Methods For Refining And Purifying 3303 Metallic Silicon Outside The Furnace
Step 1: The refining gas should be continually pumped into the ladle before the silicon melt is released. The silicon melt is then released into the ladle from the submersible furnace. The silicon water in the ladle is first heated at the same time. insulating
Step 2: Add the refining agent to the ladle, expel air from the boiler and produce slagging for refining after the first temperature rise;
Step 3: Warm up the remaining silicon water in the bag by reheating it;
Step 4: After increasing the temperature once more, modify the refining gas flow rate, add the refining agent to the lifting bag, expel air from the furnace and create refining slag; Step 5: After the external refining process is finished, separate the silicon and slag, and then High-purity 3303 metallic silicon is the result of pouring.
The following advantages can be obtained by refining and purifying 3303 metallic silicon outside of a furnace:
- The silicon water can be refined more than once to increase the silicon body’s purity by executing secondary heating and modifying the refining gas amount.
- To reduce energy consumption, fully utilize the silicon melt’s ability to self-heat.
- The materials are easy to work with, won’t harm the environment, and need little effort. It can fulfil the standards of green metallurgy and accomplish clean production.
The ladle is continuously filled with refining gas prior to the silicon melt being released. Air, oxygen, oxygen-enriched air, h2o, h2, ar, and n2 are all mixed together to form the refining gas, which has a flow rate of 10 m/h. The silicon melt is then released into the lifting bag from the underwater furnace while simultaneously heating and conserving the silicon water within the lifting bag. The regulated temperature is 1500°C, and the heating technique is microwave heating;
Refining agent should be added to the ladle after the initial temperature rise. A combination of sio2, cao, al2o3, mgo, nao, caf2, bao, li2o, and lif is the refining agent. Do slagging refining and air blowing outside the furnace. Upon filling the ladle with As the silicon melt volume increases, increase the refining gas inflow flow rate to 30 m/h. Next, add the refining agent to the ladle and perform slagging refining and air blowing outside the furnace. Once the slag silicon has been thoroughly refined outside the furnace, it is separated and poured to produce high-purity 3303 metallic silicon.
