Abstract
An apparatus for cleaning refractory-lined conveyor troughs for conveying molten metals and slags has a rail-guided carriage that extends across the trough and travels along the length of the trough, with a cleaning head supported by the carriage. Two wheels on the carriage travel along a guide rail on one side of the trough while a non-powered idler roller on the carraige travels along the other side. Lateral, opposed, rotatable guide rollers are provided on each side of the guide rail adjacent each wheel. Metal plates are situated in the floor beneath the guide rail, while small plates and/or shims are provided to compensate for irregularities between the guide rail and the metal plates.
