Optimized shapes of continuous casting molds and immersion outlets for casting slabs of steel

摘要

An oscillating mold for continuously casting slabs, preferably of steel, has long side walls and short side walls freely movable relative to the long side walls, and an immersion outlet. The long side walls define a center-symmetrical casting funnel having a funnel shape which is configured such that the distance between the long side walls in the casting funnel is reduced toward the outlet end of the mold and that in the meniscus area and at least along the length of the immersion outlet the funnel shape corresponds to or follows the outer cross- sectional size of the immersion outlet. The long side walls have adjacent the casting funnel a shape which is linear and planar over the mold length and center- symmetrical and concave transversely of the mold length.
