摘要： The invention relates to an oxygen lance guiding assembly having an oxygen lance feeding device, which is disposed on a tap hole drilling unit. The tap hole drilling unit has a drilling rod guiding device for a drilling rod, which is driven by a drilling mechanism, on a receptacle configured to have the drilling mechanism disposed thereon. The oxygen lance feeding device is disposed in an operating position in a space formed between the drilling rod guiding device and the drilling mechanism in such a manner that the drilling rod guiding device serves to form an oxygen lance guiding axis.

摘要： According to the present invention, a drill rod (10) comprises an elongate hollow shaft (12) with a first shaft end and a second shaft end (22), the first shaft end having a first connector for connecting the drill rod (10) to a drive mechanism, the second shaft end (22) having a first female tread (24); and an adapter (30) with a first adapter end (32) and a second adapter end (34), the first adapter end (32) having a first male thread (42) cooperating with the first female tread (24) of the second shaft end (22), the second adapter end (34) having a second connector for connecting a drill bit (46) thereto. When a drill bit (46) is connected to the drill rod (10), the adapter (30) is sandwiched between the hollow shaft (12) and the drill bit (46). The above configuration of drill rod allows a great variety of drill bits to be used in conjunction with a single hollow shaft. There is hence no need to provide a different hollow shaft if a different drill bit is to be used. Manufacturing costs of drill rods do hence not have to be considerably-increased if a variety of drill bits are to be used.

摘要： An improved thermal lance is made of a low carbon steel sheath having an internal bore and a thin cylindrical rod that is roll-formed from low carbon steel sheet. The rod being sized for conforming fit in the bore of the tube and has a length dimension that is longer than the length of the tube. The rod is inserted into the bore of the tube and allowed to move axially within the tube under propulsion of the pressurized oxygen to allow the rod to be burned at a rate independent of the burn rate of the sheath. One or more apertures in the tube restrict the flow of oxygen until the rod is ignited. An O ring located near the fuse protector of the lance housing keeps the lance from moving during routine handling and storage.

摘要： A device for removing worn nozzle bricks or nozzle linings from the tap holes of metallurgical vessels including a spreading device, which can be introduced into the nozzle brick or tap hole, and a drive for extracting the nozzle brick or lining by means of the spreading device. The spreading device is arranged on a tool holder which can be displaced axially on a support, in particular a carriage. The tool holder can be connected to at least one drive. The tool holder advantageously includes an axial cavity in which a toothed shaft is rotatably mounted. The toothed shaft meshes with the toothing of at least two, and preferably three, spreading jaws which slide radially in the tool holder.
