Abstract
The invention relates to a bellow compensator for a charging installation of a metallurgical furnace. The bellow compensator comprises an inlet end pipe 40 and an opposite outlet end pipe 42 and a bellow section 44 arranged between the inlet end pipe 40 and the outlet end pipe 42, the bellow section 44 being formed by a series of folds and allowing relative movement between the inlet end pipe 40 and the outlet end pipe 42. According to the present invention, a non-structural flexible liner 60, preferably wire mesh gasket, is arranged along an inner wall 62 of the bellow compensator and extends over at least some of the length of the bellow section 44. The non-structural flexible liner 60 has a first end 64 and a second end 66, wherein the first end 64 is fixedly connected to the inlet end pipe 40 and the second end 66 is fixedly connected to the outlet end pipe 42.
