1. Ladle bottom made of a refractory ceramic body (10) with an upper surface (10o), a lower surface (10u) and a pouring channel (16) extending between upper surface (10o) and lower surface (10u), further comprising a diffusor box (DB), being defined by a deepened section of said upper surface (10o), wherein the said diffusor box (DB) is characterized by the following features:
a) it is arranged at a horizontal distance to a surface area (10o) of the ladle bottom used as an impact area (10i) for a metal melt poured onto said ladle bottom, b) it defines a secondary upper surface (10od) of the ladle bottom, vertically below the upper surface (10o), c) an indentation (IN), extending from said secondary upper surface (10od) towards the lower surface (10u) of the ladle bottom and defining a tertiary upper surface (10oi) of the ladle bottom, vertically below the secondary upper surface (10od), wherein d) the pouring channel (16) runs through said diffusor box (DB) and indentation (IN). |
