Steel Making

The steel making 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.

Iron Ladle

The iron ladle is a critical molten metal transporting vessel since it is usually carried on the top of steel making shops by overhead cranes, and consequently its failure can cause serious problems. The Saint-Gobain refractories aim for maximum safety as well as optimized performance.

Iron ladle products and benefits
Products	Characteristics	Application	Benefit
Brick	Al₂O₃-SiC-C	Linning	High mechanical resistance High thermal resistance High chemical resistance
Castable	Al₂O₃	Ladle Border	High mechanical resistance

Basic Oxygen Furnace

Considered to be the heart of a steel shop, the Basic Oxygen Furnace (BOF) is a very complex equipment in terms of operation conditions, making it crucial for refractory suppliers to understand all the aspects related to it. Our BOF specialists are capable of delivering the solution that maximize your benefits by enhancing metallic efficiency and reducing refractory specific consumption.

Electric Arc Furnace

The electric arc furnace is essential for the re-processing of steel scrap, and this very aggressive process requires a large quantity of high quality refractories. Bricks and monolithics are made with carefully selected raw materials and controlled processes, to ensure the resistance and safety of its solutions.

Steel ladle

The most versatile vessel in a steel shop, the steel ladle has an increasing importance due to the modern requirements of secondary refining processes. Also known to be the equipment that consumes the biggest amount of refractories in a steel shop, its optimized design is essential for cost reduction, energy management and steel quality. In association with the newest Japanese technologies, our solutions not only withstand the most aggressive conditions but also are tailor made to reach the specific needs of each customer.

RH Degasser

The RH degassing system is essential for steel shops to meet the modern specifications of steel quality. This equipment process requires a special kind of refractory, the ultra-high temperature MgO-Cr₂O₃ fired bricks, that have excellent corrosion resistance and thus achieve longer operation life. The recent developments of Saint-Gobain in partnership with a Japanese refractory supplier have also made possible to reach high resistance to thermal cycling in its projects.

Unburned Bricks	MgO-C	Vessel walls	High thermal shock resistance
Gunning mixes	MgO (silicate bonded) MgO (phosphate bonded)	Cold and hot repair	High performance High Adhesion Low rebound

Flow Control

The final process in which the steel is liquid, the continuous casting requires a series of special refractories that have an enormous influence on the final steel quality. They are responsible for controlling the flow rate, protecting from oxidation, facilitating the inclusion flotation and allowing a good flow pattern inside the mold. The Saint-Gobain refractories division works together with a very strong Japanese partner in order to deliver high quality and high performance products for this segment.
