What's The Types Of Carburizers

Carburizers are the "carbon-replenishing experts" of the metallurgy and foundry industries, primarily used to restore carbon lost during the iron and steel melting process. Today, let's explore seven common types of carburizers-be sure to save this buying guide!

1️⃣ Calcined Type: Made from high-temperature calcined anthracite or petroleum coke; low cost but slightly lower reactivity-ideal for those on a budget.
2️⃣ Graphite Type: Features an extra graphitization step, resulting in a highly stable carbon structure; the perfect choice for high-end casting.
3️⃣ Artificial Graphite: Refined from petroleum coke at high temperatures; boasts exceptionally high carbon content and ultra-low sulfur and nitrogen levels-the top pick for high-end cast steel components.
4️⃣ Petroleum Coke: A by-product of crude oil processing; offers high fixed carbon and unbeatable cost-performance-a favorite among foundries.
5️⃣ Coal-based Type: Produced from anthracite; lowest cost but tends to have higher sulfur content-suitable for standard products like gray iron castings.
6️⃣ Natural Graphite: Higher ash content; typically used as a supplement-much like a finishing powder for makeup.
7️⃣ Coke Type: Specifically designed for electric steelmaking furnaces; rarely used for cast iron-an essential tool for industry professionals.
