Definitions
- the invention relates to a plug rod arrangement on casting furnaces and other metallurgical vessels according to the preamble of claim 1.
- nodular cast iron can be mentioned, which is poured from a casting furnace, e.g. from an ASEA casting furnace of the Presspour type, as described in the ASEA brochure AU 10-103.
- Similar problems as with spheroidal cast iron also exist with other types of melts.
- the slag piles or the like on the sealing surfaces between the stopper rod and the pouring hole brick can cause leaks.
- the invention has for its object to develop a plug rod arrangement of the type mentioned, in which an impairment of the pouring accuracy and the tightness of the plug rod closure by slag deposits can be avoided.
- the sealing surface between the pouring hole brick and the plug rod can be cleaned.
- This rotation of the stopper rod can occur after each closure of the vessel or. after several closing operations.
- This turning of the plug rod is in addition to the movement of the piston. In certain cases, e.g. if you want to save time, the piston movement and the plug rod movement can also take place simultaneously.
- the piston tip can e.g. consist of ceramic material, which can be provided with steel reinforcement or other reinforcement.
- the stopper rod is made of ceramic material.
- 5 denotes a pouring furnace or another metallurgical vessel which is provided with a pouring brick 4.
- the pouring of melt from the casting furnace 5 is controlled by a stopper rod 2.
- the Plug rod is provided with a central or substantially central channel, in which a piston 3 is arranged to be able to move back and forth.
- the lower part of the piston that is to say the part which reaches the area of the pouring hole brick, preferably consists of ceramic material which can be provided with steel reinforcement or another reinforcement.
- the piston 3 can be moved back and forth through the opening of the pouring hole 4 in the longitudinal direction of the stopper rod, any slag present in the pouring opening of the pouring hole 4 being removed.
- the piston 3 in the stopper rod 2 has essentially the same diameter as the opening in the pouring hole brick 4. After each pouring, a pressure can 1 presses the piston 3 through the opening in the pouring hole brick 4 via a rod 7 and thereby removes the slag that has accumulated there .
- the piston In order to prevent the piston from being damaged by the high working temperature, the piston - at least at its lower. End - made of a high melting point material such as ceramic material (see above).
- the plug rod can execute a rotary movement, which is brought about, for example, by a pneumatic cylinder 6. This rotary movement can take place either after each closure or after a number of closures, for example after every tenth closure. The rotary movement can take place independently of the movement of the piston 3 and / or together with it.
- the embodiment of the invention described with reference to the figure can be varied in many ways within the scope of the general inventive concept disclosed.
- the arrangement according to the invention is not only for casting of nodular cast iron, but can also be used when casting other melts.
- the invention can be used not only for pouring furnaces, but for all types of metallurgical vessels with pouring stone.
