Steelmaking
Leading steelmakers favor Calderys
Leading steelmakers favor Calderys refractories for their:
- Carefully chosen refractory products technologies, that are specifically designed and formulated to help enhance steel cleanliness.
- A complete understanding of the critical factors for steelmaking and refractory consumption; including installation, energy consumption, CO2 emissions, circular economy, and environmental footprint.
- High end maintenance products and services, specifically designed and optimized for maximum effectiveness.
- Dedicated R&D program that strives for innovation, within the scope of product development, installation practices, equipment innovation.
OUR SERVICES
Gunning Maintenance
When it comes to gunning and repair, our approach is designed to strike a balance between equipment availability and refractory lifespan. We have developed specific machines for each type of equipment, with a gunning capacity of close to 200kg/min. All machines are available with electric batteries, for lower CO2 emissions.
Fluid Flow & Numerical Simulations
We can conduct customised studies to optimise metal flow in the tundish based on multiple criteria including steel temperature, tundish dimensions and flow objectives.

Your Equipments
BOF Converter
The basic oxygen furnace (BOF) process is a method of primary steelmaking in which carbon-rich hot metal (produced by a blast furnace), is made into steel. It is one of the most common steel production process.
All Details
Electric Arc Furnace (EAF)
An electric arc furnace (EAF) is a furnace that heats the metal by means of an electric arc. Maximizing its availability is a key challenge for steelmakers.
All Details
Steel Ladle
The steel ladle is a bucket-shaped vessel used to transport and pour out molten steel. Calderys solutions are customized depending on the size of the ladle and the operating requirements.
All Details
RH Degasser
This vessel focuses on degassing the molten metal in order to produce ultra low carbon steel grades.
All Details
Tundish
The tundish is a critical reactor within the steelmaking process, where flow dynamics, refractory design and insulation requirements play a key role in ensuring and improving steel cleanliness.
All Details
CAS-OB
The CAS-OB (composition adjustment by sealed argon bubbling–oxygen blowing) is a ladle treatment process, used for the heating and alloying of steel.
