DEVICE FOR INSERTING A REFRACTORY BLOCK INTO A TAPHOLE STRUCTURE OF A METALLURGICAL VESSEL, IN PARTICULAR A BASIC OXYGEN FURNACE, AND A METHOD FOR AN AUTOMATIC SUPPLY OF THE REFRACTORY

摘要

A device is provided for inserting a refractory block (20) into a taphole structure (10) of a metallurgical vessel, in particular a basic oxygen furnace (BOF). The refractory block (20) is carried by a mounting unit (25) and having a proximate end (26), which can be introduced into the taphole. A distal end (27) with locking elements (28), which can be coupled to a locking plate (31) of the vessel, is disposed at the outside of the taphole (21) of the vessel (11). The refractory block (20) can be introduced into the taphole structure (10) until the locking elements (28) of the mounting unit (25) can be attached to and coupled with the coupling head (30) with a manipulator. This mounting unit (25) can be respectively uncoupled also with the manipulator, when the refractory block (20) is mortared and fixed in the lining (12), whereby the mounting unit (25) can be decoupled and removed solely out of the taphole (21). That enables the refractory block replacement and the gunning of refractory material from the inside of the furnace more easily.
