A review of ECSC-funded research on mould powders
Seventeen ECSC-funded research projects on the performance of mould powders used in the continuous casting of steel are reviewed. These powders are used to protect the steel from oxidation, provide thermal insulation to prevent partial solidification of the metal surface, absorb inclusions in the steel, lubricate the strand and provide homogeneous heat transfer between the strand and the mould. The surface quality of the steel product is greatly affected by the performance of the casting powder used, at each stage of the process. Details are given of the quality control of the composition of casting powders, the melting of powders, the formation of a molten pool, the infiltration of molten slag into the mould/strand gap, the effect of powders on shell formation, the formation of slag films, the transfer of heat between strand and mould, the lubrication of the strand, surface defects and sticker breakouts.
