Description
Technical Field
The utility model relates to an electroslag furnace charging field, in particular to electroslag furnace charging in-process electrode centering device.
Background
In the electroslag remelting furnace in the prior art, a material rod and a dummy electrode are connected in a mode that an automatic auxiliary electrode clamping mechanism with reliable insertion and absolute contact of an auxiliary electrode is provided at the bottom of the material rod. When the ball screw of the material rod is connected with the auxiliary electrode joint, the external copper pipe is pressed down pneumatically, and the locking ceramic ball is pressed down in the groove of the auxiliary electrode by the cam ring. Thus, the copper material rod is ensured to be fixedly contacted with the copper ring on the auxiliary electrode. However, the premise of this operation is that the auxiliary electrode connector must be inserted into the copper rod interface, which requires that the dummy electrode be concentric with the material rod after the dummy electrode is lifted and contacted with the bottom, so as to ensure that the dummy electrode connector can be completely inserted into the material rod interface.
However, in the actual operation process, due to the welding concentricity deviation of the electrode and the dummy electrode or the non-horizontality of the bottom of the electrode relative to the bottom water tank, the dummy electrode is not concentric with the material rod after the electrode is grounded, and the operation of connecting the auxiliary electrode and the material rod cannot be performed. In order to solve the problem, a common method is to position the dummy electrode by using three or four wooden plugs at the mouth of the crystallizer, but the method has the problems that the wooden plugs are difficult to take out and need manual adjustment when being positioned, and the operation difficulty is relatively large.

Detailed Description
The present invention will be further described with reference to the accompanying drawings, which are not intended as limitations of the present invention: the utility model provides an electroslag furnace charging in-process electrode centering device which characterized in that: the device comprises an electrode centering auxiliary device 1 and an electroslag furnace lower smoke cover 2, wherein the electrode centering auxiliary device 1 is matched with the electroslag furnace lower smoke cover 2 for use; the electrode centering auxiliary device 1 consists of two symmetrical parts; the electrode centering auxiliary device 1 comprises a device substrate 3 and a positioning plate 4, wherein a semicircular arc segment 7 is arranged in the device substrate 3, the positioning plate 4 is arranged on the lower surface of the device substrate 3, and the positioning plate 4 comprises a positioning plate A5 and a positioning plate B6.
The positioning plate 4 is rolled and formed by a stainless steel plate with the thickness of 3mm and then welded on the device substrate 3. The motor centering protection cover 1 on bilateral symmetry be provided with bolt hole 8, two parts electrode centering auxiliary device 1 fixed through bolt structure. The size of the positioning plate A5 and the size of the positioning plate B6 correspond to the size of the smoke hood 2 under the electroslag furnace.
In the specific implementation: as shown in fig. 1. After the auxiliary device is manufactured, the two halves of the auxiliary device are respectively placed on the lower smoke cover according to the positions, and after the positions are determined, the two halves of the auxiliary device are locked by bolts and nuts. Note that when the tool equipment is installed, the electrode falls down integrally and is about to touch the bottom, because if the tool equipment is installed in advance, if the outer diameter of the electrode is larger than that of the false electrode, the electrode cannot be loaded into the furnace, because the size of the inner circle opening of the tool equipment is matched with that of the false electrode.
