Calcined Limestone (Metallurgical Lime) for Steelmaking
High-Purity Quicklime Optimized for Iron & Steel Production
Our calcined limestone — also known as metallurgical lime or quicklime — is produced by calcining high-grade limestone at high temperatures in modern kilns. With strictly controlled chemical composition and consistent reactivity, it is an essential fluxing agent in the steel industry.
Key Applications in Steelmaking:
Basic Oxygen Furnace (BOF) Process
As a primary flux, our quicklime rapidly combines with impurities such as silica, phosphorus, and sulfur to form a low-melting-point slag. This protects furnace linings and improves steel quality.Electric Arc Furnace (EAF) Steelmaking
Metallurgical lime accelerates slag formation, enhances foaming slag practice, and increases energy efficiency while reducing electrode wear.Secondary Refining (Ladle Metallurgy)
Precisely controlled lime addition enables effective desulfurization, dephosphorization, and inclusion modification, producing cleaner, higher-grade steel.Sinter Plant
Finely ground quicklime improves the permeability and strength of sinter feed, increasing sinter productivity and reducing fuel consumption.
