2 Trends, expectations and issues in Annealing processes RAPID HEATING CYCLES ON CARBON STEELS ( C/s): EcoTransFlux induction enable new annealing processes, due to superior intrinsic abilities: Higher heating density : 2 MW/ squ. meter of steel strip higher treatment temperature: up to 1200 C mainly 950 C Faster temperature increase: up to 400 C/s Direct Benefits: on the products: mechanical resistance improved of the steel by 5 to 10%, preservation of elongation capability. Indirect Benefits: significant weight reduction of steel assemblies like car bodies, and associated benefits for the environment (fuel consumption and CO2 emissions reduction), 2

3 Trends, expectations and issues in Annealing processes RAPID HEATING CYCLES ON SILICON STEELS ( C/S), Decarburisation Lines EcoTransFlux inductors are complementary to the Gas-Heating furnaces for the Decarburisation lines Direct Benefits: Better electrical characteristics for the final product compact design Indirect Benefits: environmental impacts (CO2 emissions ), 3
