Steelmaking

The steelmaking process, where molten iron becomes solid steel, involves several stages of thermal and chemical treatment requiring a variety of refractory linings that are compatible with many application conditions.

 

These linings must have excellent resistance to steel and basic slag corrosion, as well as high thermal shock and oxidation resistance.

 

Saint-Gobain services this market with innovative refractories solutions that present high performances and contribute to enhanced steel quality.

Steel Ladle

Steel-Making-Solution-Steel-Ladle

Already the most versatile vessel in a steel shop, the steel ladle has become increasingly important due to secondary refining process requirements.

 

A steel ladle is also the piece of equipment that consumes the largest amount of refractories in a steel shop, making design optimization essential for cost reduction, energy management and ensuring steel quality.

 

Saint-Gobain Performance Ceramics & Refractories employs current Japanese technologies, ensuring its solutions can withstand the most aggressive operating conditions while being tailor-made to meet the specific needs of each customer
