Abstract: A converter arrangement includes a tiltable converter vessel surrounded by a casing on whose ceiling a principal discharge conduit for conducting away refining gases, and a secondary discharge conduit for conducting away the smoke forming during charging and pouring, are connected. One side wall of the casing has an opening closeable by a door. The casing is widened in the tilting direction of the converter and a car carrying a charging container is movable into the widened space through the opening in the side wall. The opening can be completely closed when the car is in the moved-in position during charging and pouring off.
