Dear experts, I have a question: does anyone know what the difference is between the coke used in iron production and that used in calcium carbide production? Please let me know; I’m eager to find out. Thank you!~~
Coke has a wide range of uses; it is employed in various industries such as iron smelting, casting, calcium carbide production, sintering, gas production, and the processing of non-ferrous metals. Different uses require different specifications for coke. 1. Requirements for coke used in iron production: The lump size should be >25 mm; the ash content (A) and sulfur content (S) must not be too high. It should also possess a certain resistance to crushing (M40) as well as wear resistance (M10). 2. Requirements for coke used in calcium carbide production: High fixed carbon content and low ash content are required; high strength is not necessary. The particle size should be between 15 mm and 20 mm. Therefore, it is appropriate to use blended coal containing petroleum-derived delayed coking coke to produce coke for calcium carbide production.
Comrade poster, it’s “coke”, not “ “Coke”!
Coke used for calcium carbide production is required to have low ash, low sulfur, and low phosphorus content, as well as a high fixed carbon content; the phosphorus level must be less than 0.02. In fact, these are the same requirements as for ferroalloy coke. Strength is not a requirement, and small lumps with little slag are preferred; good blue coal can also be used, given its lower cost. Produced using high-volatility gas coal as raw material.
