IRON & STEEL INDUSTRY
In modern steelmaking, quicklime is an essential slag-forming material. It reacts with impurities such as SiO2, phosphorus, and sulfur to form a solid slag, which is readily separated from the molten steel. Typically, approximately 30 kg of quicklime is added per ton of molten steel.
Minben Calcium supplies high-reactivity lump quicklime in particle sizes of 15–50 mm, specifically designed for steelmaking applications. Due to its excellent high-temperature resistance and structural stability, Minben quicklime is an ideal choice for use in basic oxygen furnaces (BOF) and electric arc furnaces (EAF), helping produce cleaner and stronger steel.
During secondary refining processes, such as ladle furnace (LF) operations, lime injection can further enhance deep desulfurization and dephosphorization, enabling the precise control of composition and temperature required for special and high-grade steels.

Core Advantages
High Purity & Reactivity
High purity (CaO ≥ 93%) and high reactivity (≥ 400 mL) ensure rapid and complete reactions, significantly enhancing desulfurization and dephosphorization efficiency.
Low Impurity Content
Very low levels of harmful impurities, including sulfur and SiO2, help minimize the risk of secondary contamination.
Cost-Effective Performance
Compared with alternative products, Minben lime delivers comparable or superior performance at a lower overall cost.
