| 摘要 |
The invention relates to a pouring crucible which is made of refractory and corrosion-resistant material comprising an impact base which is surrounded by a lateral wall, said pouring crucible being used to receive molten metal flowing from a pouring ladle. Said pouring crucible is arranged in an intermediate container (tundish) which is used to still the molten metal and to hold back slag. The invention is characterised in that one section of the lateral wall of the pouring crucible comprises an opening (4) which opens into a balcony-shaped trough (5) that is adjacent to the outer wall of the pouring crucible. Preferably, the impact base comprises a projection which is arranged essentially in the centre of the pouring crucible, is in particular rotationally symmetrical and tapers towards the exterior, said projection being cone-shaped (3) having a rounded top. The height of said cone is approximately 30 to 60% of the inner height of the pouring crucible (1). |
