Lime in the steel industry is essential for steel quality

Lime is a key raw material in modern steel production, playing a crucial role in multiple stages of the manufacturing process. Thanks to its unique chemical properties, it is vital for the removal of impurities such as sulphur and phosphorus, contributing to the production of high-quality steel.

With over 300 years of history, Fassa Bortolo has developed a deep understanding of the steel industry’s needs, translating this knowledge into a comprehensive range of specialised products. Our continuous commitment to research and development has enabled us to evolve alongside the sector, creating innovative solutions such as the low-carbon ELC line and Flow Lime products.

Applications of quicklime in the iron and steel industry

Lime for pig iron production

In the sintering process of iron ore, hydrated lime and calcium carbonate are essential for obtaining the raw material for pig iron. Our manufacturing process ensures lime with a constant and controlled composition, which is essential for stable sintering performance.

Lime for desulphurisation and dephosphorisation

Our highly reactive quicklime optimises the removal of sulphur and phosphorus from steel. Its high purity and reactivity enable superior results with lower material consumption, reducing operating costs in the refining process.

Lime as functional additive for the slag

Our dolomitic mixtures strategically combine high-calcium and dolomitic lime, optimising storage while ensuring the required reactivity from the calcium component. The controlled MgO content makes slag less aggressive towards refractory linings, significantly extending their service life and reducing steel plant maintenance costs.

Lime for reducing furnace lining wear

Our high-MgO dolomitic lime has been developed to extend refractory life. Its high magnesium content helps protect furnace linings, greatly reducing maintenance costs.

Calcitic Quicklime

Produced through an exclusive soft burning process using biomass fuel, this lime ensures maximum reactivity and low CO₂ content. The rigorous selection of limestone and ongoing quality controls guarantee high purity for consistent, reliable performance.

ELC

The ELC line combines a high CaO content with extremely low carbon and impurity levels. Its outstanding reactivity, thanks to the soft burning of limestone and the resulting high specific surface and porosity, makes it the perfect choice for the production of stainless steel and low-carbon steel.

Flow Lime

Finely ground products with excellent fluidity, enhanced by special fluidizing agents and optimized particle size distribution. Direct lime injection into slag and fast dissolution ensure maximum efficiency, while reduced dust production improves safety and environmental conditions.

Dolomitic Quicklime

With high MgO content and exceptional purity, Fassa’s Dolomitic Lime is the ideal solution for both the iron & steel industry, where it extends refractory brick life and reduces costs, and for the most demanding chemical sectors.

Flow Lime 40%

A highly fluidity micronized dolomitic lime optimised for direct injection into steel slag. Its excellent dispersibility, combined with high magnesium content, reduces slag aggressiveness towards refractory materials, significantly extending their operational lifespan and optimising maintenance costs.

Dolomitic Mixtures

An exclusive product line combining Calcitic and Dolomitic Lime, manufactured at the Montichiari (BS) plant. These blends offer the advantages of both materials, optimising storage and logistics, with the possibility of customizing MgO content to meet specific client needs.
