Definitions
- the invention relates to a method for disclosing or Closing a tap hole in a refractory delivery Wall of a metallurgical vessel, for example a copper-smelting furnace, a blast furnace and the like, preferably by means of one metallic closure part.
- a pneumatic or hydraulic operable hammer in particular hammer drill. consisting essentially of a striking mechanism with a tool-related one Transmission part, which is adjustable on a percussion piston, as well optionally with a rotary motor operatively connected to the transmission part Gear and the use of the hammer for an opening and / or Closing the tap opening in a metallurgical vessel.
- melts for the production and / or processing of Certain melts can advantageously be provided in one-piece closure parts be, by means of which an open position and a closing of the The vessel according to the procedure.
- This if necessary preferably metallic closure parts are in the tap hole of the Melt vessel introduced and must be for a required period of time complete completion or inclusion of the batch or the liquid melt to ensure.
- an open with is possible secured or desired cross-sectional shape of the rack required to to achieve a largely cylindrical, non-shattering melt stream.
- Another form, often used only as a highly effective emergency measure opening a tap of metallurgical vessels is an opening or closing Burn out a tapping channel with oxygen.
- Oxygen by means of a metal tube, in particular steel tube, which on Outlet end above the reaction temperature of the metal or steel with oxygen is heated, when the same is placed on the refractory sealing compound Tapping opening introduced by local liquefaction of the mass.
- a Deflection of the focal beam can easily become one for one Lead unwanted and unfavorable channel shape, which in the Consequence also causes sealing problems and / or expensive repairs.
- a Closing and opening the tap hole of a metallurgical Vessel using a predominantly cylindrical or slightly tapered Closure part, which is effective in the tap opening is provided.
- This Closure system or this device advantageously provided one each Extensive open position of the rack and the refractory material gentle closing of the same, but caused in the operative and dangers and problems in the area of plant technology.
- the invention is concerned with a state the technology-enhancing, sequential discharge technology of Batches or melts from metallurgical vessels. It is a goal, one Specify the method by means of which a melt is tapped and Closing the tapping channel consequently increases safety, better Workflow and increased economy can be achieved.
- Another The object of the invention is a hammer with a striking mechanism, in particular for Open and to create a tap hole with which Machining in both directions of the axis of the tool, preferably one Movement of a closure part in a refractory delivery, simple, short-term and, if necessary, shape-preserving for opening a brick lining metallurgical vessel is made effective and safe.
- This goal is achieved in a method of the type mentioned at the outset by that the closure part in the region of the tapping into the intended or desired direction acting on or restoring force, if necessary at simultaneous exertion of a torque and consequently the force and / or a striking rectified component is superimposed on the moment and the closure part is moved.
- the advantages achieved with the invention are in particular due to the fact that a trigger or insertion force on the closure part blows and if necessary, a torque can be superimposed, whereby on the one hand by Creation of sliding friction reducing the forces on the lining of the Tapping area and thus largely preserving the shape of the melt channel is given, on the other hand, a quick and easy opening and Closing the tap opening is made possible, so that an inexpensive, exact batch sequence with high operational reliability can be achieved.
- the striking component (s) pass through the axial force applied to the closure part is or are triggered because so that the connecting elements to the tool are particularly protected or have a particularly long service life.
- the further object of the invention is in a hammer of the aforementioned type solved in that the axially displaceable in the striking mechanism, at least on the one hand with a tool or similar means connectable transmission part an inner shaft and two opposite this in the axial direction, in Diameter enlarged anvil parts is formed and in the striking mechanism piston which can be moved back and forth by means of the pressure medium has a tubular shape and the inner shaft of the transmission part is axially displaceable coaxially encloses, each by an axial displacement of the transmission part one of the anvil parts to the opposite end face in the area of a End position of the cattail is adjustable and impact energy can be applied.
- the advance or retraction of the tool can be particularly favorable on the Properties of the material to be processed and on the Tool cutting range can be matched when the cattail through a Reversing device can alternatively be acted upon with pressure medium, one Regulation of the impact energy of the cattail by the amount per unit of time and / or the pressure can be generated as the supplied medium.
- Tool 3 is now switched on to an object to be processed, possibly a stopper in a tap opening or the like, the transmission part 2, the has an anvil part 22 and 23 on both sides, axially in the striking mechanism 1 moved until, as is shown schematically, the anvil part 23 with a Contact surface 231 on a support surface 12 in the striking mechanism 1 in the axial direction of the Tool 3 is present.
- the contact force of tool 3 caused a counterforce, which on the contact surface 231 of the anvil part 23 by means of Support surface 12 is introduced into the striking mechanism 1.
- the transmission part 2 can also optionally Activation of a transmission 5 by a rotary motor 6 with a torque be charged.
