The steelmaking process typically consists of the following key steps:
Raw Material Preparation
This includes molten iron, scrap steel, and other necessary materials such as fluxing agents (e.g., limestone).
Converter Steelmaking
As the core process of steelmaking, it involves steps like charging, blowing, slag formation, decarburization, and temperature raising. During this process, carbon and other impurities in the molten iron are removed through oxidation, while the chemical composition and temperature of the steel are adjusted.
Refining
The molten steel from the converter usually requires further refining to eliminate residual impurities, adjust the chemical composition, and control the steel's purity.
Continuous Casting
The refined molten steel is continuously cast into billets, blooms, or slabs with specific cross-sectional shapes and dimensional specifications. This process demands precise control over the cooling rate and the quality of the cast products.
Steel Rolling
The cast billets (blooms/slabs) undergo a rolling process to be fabricated into steel products of various shapes and sizes.
Quality Control
Strict quality control is implemented throughout the entire steelmaking process, including inspections of raw materials, semi-finished products, and finished products, as well as monitoring of the production process
