Steel Enhancing Ladle Flow (S.E.L.F.)

Al2O3-MgO Monolithics

Steel Enhancing Ladle Flow (S.E.L.F.) is an innovative solution designed to improve yield in the steelmaking process. S.E.L.F. enables printing of custom flow profiles on monolithic steel ladle bottoms, optimizing flow. S.E.L.F. also reduces the excessive steel retention typically linked to scrap and rework, resulting in considerable resource savings and carbon footprint reduction.

FAQ

Can S.E.L.F. technology be applied to any steel ladle design?

Saint-Gobain Performance Ceramics & Refractories’ S.E.L.F. technology can typically be applied to any steel ladle that can accommodate a monolithic bottom. The company’s technical team will evaluate each individual case, proposing a unique solution for each customer's steel ladle bottom configuration.

Is it possible to measure the reduction of scrap generated by this solution?

Saint-Gobain Performance Ceramics & Refractories and its partner companies combine computer simulations and specific customer-focused technical proposals to generate a detailed report on the potential reduction in scrap generated. Using this information, customers can make informed decisions around the use of SELF technology.

What are the benefits of adding Saint-Gobain Performance Ceramics & Refractories’ S.E.L.F. technology to steel ladles?

S.E.L.F. technology can be used to create a unique and long-lasting profile at the bottom of a steel ladle. This profile results in optimized steel flow while minimizing the impact of vortex and drain, and considerably reducing the retention of steel and scrap generated at the end of continuous casting.
