1. What is Carburetant? Understanding the Foundation of Carbon Additives
Carburetant—also known as carbon raiser or recarburizer—refers to high-carbon materials added during iron and steel making to increase and precisely adjust carbon content. These agents are critical in determining the metallurgical quality, mechanical performance, and cost-effectiveness of cast iron and steel products.
Main related types include:
- Graphite recarburizer: High-purity graphitized carbon with excellent graphitization degree.
- Coal-based recarburizer: Produced from anthracite or coke; cost-effective.
- Petroleum coke recarburizer: Good purity, commonly used in steelmaking and foundries.
