Definitions
- the invention relates to a located at the free end of a component of an electric furnace forming Elektrodentragarms contact plate replaceable attributable contact jaw for the means of a leading on Elektrodentragarm clamping bracket kontwill tbecrowdedd contrast, can be brought to the interchangeable electrode.
- the object of the invention is to develop a solution which, based on a contact surface formed on the one hand over a large area against the component of the electrode and on the other hand against the electrode interacting with it over a large area, affects the current transfer from the contact plate on the attached thereto, interacts with the electrode interacting contact jaw, at least reduces.
- the object is achieved with a contact at the free end of a component of an electric furnace forming Elektrodentragarms arranged contact jaw for contact by means of a leading on Elektrodentragarm tensioning contact against contrast engageable electrode replaceable, which is characterized in that against a portion of the electrode surface to plant bringable contact jaw is centrally provided by an expiring toward the support arm passage, which is continued in the support arm.
- Burning occurring during operation is continuously carried out by the passage formed in the contact jaw and leaving the support arm. To a noticeable impairment of the current transfer from the component the ElektiOdentragarms forming contact plates on the interacting with the electrode contact jaw it does not come.
- Figure 2 is a view of the component of the ensemble forming contact jaw from its arm-side plant side (arrow II in Figure 1).
- 11 denotes the front side region of the electrode support arm.
- the electrode support arm consists of a box profile which is continuous in the middle (111).
- the contact jaw 12 is attached, via Screwed connections 121 between contact jaw 12 and the component of the electrode dentragarms forming contact plates 112.
- the replaceable electrode 21 is brought against the contact jaw 12 via a non-illustrated, leading to the support arm 11 clamping member against the contact.
- the contact surfaces of Kon-. Taktbacke 12 are designated 122.
- 123 the contact jaw 12 passing through cooling channels are called.
- the contact jaw 12 is centrally continuous (124) formed in the support arm 11 passage 111th
- a tongue and groove connection can be provided which prevents relative movements between the contact jaw 12 and the support arm 11, ie its contact plates 112. This possibility is indicated in FIG. After that are Tragarm substance formed in the contact surface 126 of the contact jaw 12 grooves 128, in which overlap with protrusion springs 129, the supernatant inserted in the attached to the support arm 11 Kontalctbacke 12 in the front of the support arm 11 contact plates 112 formed, corresponding grooves.
