Description
Short description:
Explains raw materials and preparation processes for blast furnace input, including sinter, pellets, lump ore, coke, and air preheating.
Long description:
This module introduces the input materials and preparation processes that precede blast furnace operations. It details the sourcing, characteristics, and treatment of raw materials such as iron ores, sinter, lump ore, pellets, and coke. Emphasis is placed on chemical composition, size distribution, and preparation techniques essential for consistent furnace performance. Additionally, the module explores the use of auxiliary reductants like pulverised coal and discusses the role of hot blast stoves in preheating air. Through detailed explanations and diagrams, learners gain foundational knowledge of material preparation and input strategies that support efficient ironmaking.
What you will learn
- Identify the main types of raw materials used in blast furnace ironmaking and their physical properties.
- Describe the feed preparation processes for each input type, including sintering, pelletizing, and ore screening.
- Explain the purpose and method of hot blast air preheating using regenerative stoves.
- Discuss the use of pulverised coal injection (PCI) as an auxiliary fuel and its impact on coke usage.
- Summarize the chemical composition and quality parameters of feedstocks affecting furnace performance.
