The invention relates to a fire resistant ceramic part which can be embodied in the form of an impact pot or a casting gutter and has the following characteristics:-a base ( 10 );-at least two walls ( 12, 14 ) which extend from opposite sections ( 10 l, 10 r) of the base ( 10 ) such that at least some sectors ( 12.1, 12.3, 12.4 ) of the inner surfaces thereof run at an angle >0 and <90 degrees from a plane E-E, perpendicular to the base ( 10 ), and at opposite inclinations;-an opening (O) is configured between free ends ( 12 r, 14 r) of the walls ( 12, 14 );-the distance (dmin, qmin) between the walls ( 12, 14 ) is smaller in at least one sector ( 11 ) between the base ( 10 ) and the opening (O) than it is in the areas ( 12 u , 14 u ; 12 o , 14 o) located adjacent the opening (O) and the base ( 10 ). |
