Abstract:

A reline tower is supported by a wheeled car for movement along rails while the tower extends in a vertically-spaced relation below the bottom opening in Q-BOP type of metallurgical furnace which is supported for pivotal movement about a horizontal axis. When the tower is supported on the car for a tilting type of pivotal movement, a control system synchronizes tilting movement of the tower in relation to both displacement by the car along the rails and pivotal movement of the metallurgical furnace whereby the tower is moved into a generally upright position while the upper end of the towerextends within the metallurgical furnace. The entire tower is either pivotally attached to the wheeled car or the tower is divided into a lower straight section carried by the car to pivotally support an upper tower section. In another embodiment, the tower consists of an upper tower section and a lower tower section made up of superimposed pairs of half tower sections that are hinged together to vertically displace the upper tower section into the metallurgical furnace. According to another embodiment, the tower consists of a plurality of sections receivable one within the other in a vertically-telescoping manner.
