The invention relates to a hot-top mold for a strand casting apparatus, consisting of a hot top, which lies on the upper side of a parting agent distributor and presses it with its underside against the surface at a mold an overhang bein g formed on the radially inner surface of the hot top, which protrudes beyond the partin g agent distributor in the direction of take off of the strand, the hot top being centered and held by an outer ring, which is releasably fastened to the mold. The mold surroun ds a function ring toward the bearing surface of the mold which, together with th e parting agent distributor, forms function surfaces with adjustable roughness on the surfaces. In the parting agent distributor, radial channels are formed at the upper side and the underside, the channel cross sections at the upper side and the underside being in a ratio of 1:3 to 1:5 to one another. |
