In many steel plants, the torpedo cars (torpedo ladles) are no longer just transfer containers, but very important equipment used for liquid metal treatments such as de-sulfurization and de-siliconization. These practices entail higher temperatures, higher metal/slag turbulence due to reagent injection and greater chemical attack. Consequently, the service life of the alumina bricks or tar impregnated alumina bricks is dramatically reduced.
The Alfrax® TC line of alumina-carbon silicon carbide bricks was developed and has been supplied to customers in 18 countries. The Saint-Gobain concept enables balanced lining designs, as every area of the torpedo car has different requirements.
Saint-Gobain’s expertise in material science, computer design and Finite Element Modeling technologies, as well as thorough knowledge of the ironmaking processes, provides technical superiority when it comes to solving torpedo car refractory lining problems.
As a result, Saint-Gobain has provided more than 70 different TC refractory projects worldwide by Taylor-Made concept.
The table below indicates typical materials recommendation for torpedo ladles, especially in case of de-sulfurization treatment. The mouth is lined with BFA and Bauxite-based Alfrax®185 castable.
Supported by a well-equipped laboratory and skilled specialists, Saint-Gobain’s R&D team works in partnership with Japanese corporations focused on the development of innovative products for steelmaking, foundry and many other markets attended by Saint-Gobain.
Mindful to customer needs, Saint-Gobain applies state-of-the-art materials and engineering concepts to deliver the refractory technology which best suits each customer’s requirements. In total accordance with Saint-Gobain environmental, health and safety policy, the R&D team seeks for alternatives with minimum hazardous emission, no discarding problems after its lifetime and maximum re-utilization of refractory scraps.
When choosing a refractory product developed by Saint-Gobain, you will be selecting a high-performance, environmentally friendly and safety assured material specially designed for your specific requirements.
