Description
Technical Field
The utility model relates to an electroslag remelting equipment technical field especially relates to a hollow electroslag remelting furnace of stripping formula is with outer sediment device that connects.
Background
With the development of industries such as electric power, energy, petrochemical industry, storage and transportation, the demand of large hollow forgings applied to the fields is larger and larger, and the quality requirement of the large hollow forgings is higher and higher. The traditional production of hollow forging mostly takes a solid steel ingot as an original blank, and the solid steel ingot is firstly subjected to upsetting and punching to prepare a hollow part, and then subsequent forging and processing are carried out, so that the defects of the traditional production of the hollow forging are inevitable. The production of the large-scale cylinder forging by using the hollow steel ingot is an effective way for producing the large-scale cylinder forging. The appearance of the electroslag remelting technology of the hollow steel ingot brings a new development direction for the preparation of the hollow steel ingot. The electroslag remelting technology for hollow steel belongs to the ingot drawing electroslag remelting process, in which the inner crystallizer and the outer crystallizer both move relative to the steel ingot, and the slag crust risks cracking. At this time, if the remelting process is not appropriate, slag leakage and steel leakage can be caused. In addition, due to the existence of the inner crystallizer, when the remelting of the electroslag remelting hollow steel ingot is finished, the ingot drawing can not be stopped immediately like the electroslag remelting solid steel ingot, so that liquid slag is left in the crystallizer and removed after cooling. The steel ingot is completely separated from the inner crystallizer when ingot drawing is required to be continuously carried out, so that the inner crystallizer is prevented from being locked after liquid metal is solidified and contracted. The treatment of slag or steel leaked from the outer crystallizer and the cast ingot is not in place, which can cause great potential safety hazard. Therefore, in order to ensure the smooth production of the hollow steel ingot, the development requirement of the ingot drawing type electroslag remelting hollow steel ingot production is to research a slag receiving device which is economical, applicable, simple and convenient to operate, safe, reliable and capable of being repeatedly used.

Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Number in the figure: a bottom water tank; 2. a slag receiving disc A; 3; a support; 4. a connecting bolt; 5. a slag receiving disc B; 6. connecting the steel upright columns; 7. a base.
Detailed Description
The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.
Example (b): referring to fig. 1, the spindle-pulling type external slag receiving device for the hollow steel ingot with the specification of phi 800/350mm, namely the Mn18Cr18N hollow steel ingot, comprises a bottom water tank 1, a slag receiving disc A2, a support 3, a connecting bolt 4, a slag receiving disc B5, a connecting steel upright post 6 and a base 7, wherein the bottom water tank 1 is connected with the base 7 through the connecting steel upright post 6, the support 3 is welded on the connecting steel upright post 6, the slag receiving disc A2 and the slag receiving disc B5 are placed on the support 3, and the slag receiving disc A2 and the slag receiving disc B5 are connected through the connecting bolt 4; the outer diameter of the bottom water tank 1 is 800mm, and the thickness is 50 mm; the outer diameter and the inner diameter of the slag receiving disc A, B are 1100 mm and 780mm respectively, and the height is 150 mm; the height of the connecting steel upright post is 1000 mm. The specific using steps are as follows: firstly, welding a bracket 3 at the position with the height of 500mm of an upright column, placing a slag receiving disc A2 and a slag receiving disc B5, and connecting through a connecting bolt 4; a small amount of powdery refractory material is put into the slag receiving disc for protecting the slag receiving disc; the bottom water tank is inserted into the inner crystallizer and the outer crystallizer and is 350mm away from the lower edge of the outer crystallizer.
And in the early stage of starting the electroslag remelting hollow steel ingot, the bottom water tank is plugged after being inserted into the crystallizer. The distance between the upper edge of the slag receiving disc and the lower edge of the outer crystallizer is 50-100 mm. A small amount of powdery refractory material is placed in the slag receiving disc. And (3) pouring liquid slag at the beginning of remelting, and if the blockage is not good and a small part of slag leaks, smoothly receiving the leaked slag by the slag receiving disc. In the pumping stage, part of solid slag crust falls off, and the slag receiving disc can smoothly receive the slag crust. This is advantageous for protecting the device.
The distance between the upper edge of the slag receiving disc and the lower edge of the outer crystallizer is 50-100 mm. Therefore, the slag receiving is facilitated, whether the slag leakage phenomenon exists in the slag pouring stage and the slag pumping stage is also facilitated to be observed, and then corresponding measures are taken, so that the stable and smooth operation of the smelting process is facilitated. Meanwhile, a secondary cooling device space is reserved in the space, and air cooling or water mist cooling can be performed.
The slag receiving disc A, B is internally provided with a powdery refractory material for further protecting the slag receiving disc. The slag receiving pan A, B is connected by connecting bolts. The assembly and disassembly are flexible, and the cleaning is convenient.
The embodiment is just for easy understanding the technical scheme of the utility model, does not constitute the restriction to the protection scope of the utility model, all do not break away from the content of the technical scheme of the utility model or according to the utility model discloses a technical essence is to any simple modification, the equivalent change and the modification of doing of above scheme, all still belong to within the protection scope of the utility model.
