anglais vers français Technique / Génie Ingénierie (général) a method for controlling a flow of a molten steel in a mold

contexte "The molten steel 1 forms the molten steel discharge flow 4 proceeding to the mold short sides 8, and is then poured into the mold 6 from the discharge openings 12 immersed in the molten steel I in the mold 6. The molten steel 1 poured into the mold 6 is cooled by the mold 6, thereby forming a solidifying shell 2. When a predetermined amount of the molten steel 1 has been poured into the mold 6, the operation starts withdrawal of the cast product 5 containing unsolidified molten steel 1 in its inside with an outer shell as the solidifying shell 2. After the withdrawal is started, while the position of a molten steel bath surface 3 is being controlled to a substantially constant position in the mold 6, and the casting speed is increased to a predetermined casting speed."
