Spaced apart openings through the shell, correspond with recesses in the lining which have a transverse width which increases away from the shell. In each opening and corresponding recess is an assembly of at least to hollow cooling plates which are removably connected to the shell. A first one of the cooling plates has a transverse width which does not increase away from the shell opening whereby that cooling plate can be removed first from the assembly through the opening and at least one other cooling plate of the assembly has a maximum transverse width which permits its removal through the opening after removal of the first plate.
