(54) DEVICE FOR ELECTROSLAG FIBER

one

The invention relates to the field of ferrous metallurgy, in particular to electroslag remelting devices of ingots of various purposes and weights, including multilayer ones .5

A device for the production of ingots of various sizes by electrical remelting of metal is known, which contains two vertical columns and carriages on each column for independent movement of crystallizers and electrode holders with consumable electrodes. The carriages can be rotated relative to the column, which allows variable supply of consumable electrodes to a single mold by two to 15 meters of electrode holders.

The purpose of the invention is to create the mobility of melting electrodes on different modes in different molds, as well as the possibility of smelting ingots, different in weight and purpose.

The goal is achieved by the fact that the proposed electroslag 3 remelting device is additionally equipped with a two-column single-phase furnace with a movable vertical 25

at the same time, the wind axis of the columns of the two-column furnace and the axis of one or more columns of the three-column furnace are located in the same plane, and the distance between adjacent columns {of the furnaces does not exceed the maximum reach of the electrode holder.

FIG. 1 shows the proposed device electroslag remelting with dependent operation of three- and two-column furnaces, a general view; in fig. 2 - the same, with the joint operation of a two-column furnace and one of the columns of a three-column furnace, in FIG. 3 - two-column oven.

Claims (1)

The device contains a three-column three-phase furnace and a two-column single-phase furnace. The supporting structure of a two-column single-phase furnace is made in the form of columns 1 and 2, combined in the upper part of the beam 3. The columns of the electrode holder 5 moving vertically and the carriage 6 of the crystallizer 7 are installed. In the electrode holder 5 wedge type two mutually perpendicular cuts 8 and 9 are made with right-hand felled surfaces of the current-drive 10 in which the inventory of HOB 11 electrodes 12 are fixed. Moving the carriages 4 and 6 along the column They are implemented using differential drives 13 and 14, each of which is equipped with two electric motors to achieve, respectively, working and cruising speeds. The remelting of consumable electrodes 12 is produced in a cristizer, a talizer 7 by the counter-dvig method, while the ingot 15 remains on the pallet 16; I mounted on a trolley 17 that travels along a track 18. The two-column furnace is equipped with a short network connecting the electrodes 12 to two transformers operating autonomously with it or according to an integrated circuit together with a three-column three-column three-phase furnace contains three copones 19, 2O and 21, on each of 2 of which is located the carriage 22 with the electrode holder 23, stirring along the column with the help of a differential drive 24, the gear of which interacts with the raik 25 mounted on the column, and the drive 3 is equipped with two electric motors 26 for reaching working and marching speeds. Each carriage 22 is fitted with electrode holders that can be radially rotated by means of a mechanism 27, which simultaneously serves to extend the electric holder by moving gear 2 8 Bbs of the outlet shaft of rail 29, which is rigidly connected to the electrode holder 23. The electrode holder rotates around the axis of the column using gear 30 and gear Venda 31, rigidly connected with the bandages 32 and 33 mounted on the carriage. Each electrode holder 23 can be fitted with two electrodes 34 each with WEDGE-shaped inventory heads 35. All three columns are connected by a common cross member 36 of the crystallizer 37 and are equipped with a vertical movement mechanism 38. The melting of the round large-tonnage ingot 39 is carried out within the area bounded by three columns 19, 20 and 21, by moving the crosshead 36 with the crystallizer 37 towards the consumable electrodes 34. The unloading of the crosshead 36 is carried out in the cavities of the columns as well as the ropes 41 and blocks 42. Rolling out the ingot 39 is produced by trolley 43 along the track 44. On each of the columns of the three-column furnace, ingots 45 and 46 of any shape can be melted outside the area bounded by columns 19, 20 and 21. In this case, the melting can are in a bifnlary scheme using electrodes 47 and 48 in the mold 49, and in a monofilar scheme using an electrode 50 in the mold 51. When a two-column furnace and a nearby column 21 of a three-column furnace work together, the electrodes 52 melt into horizontal sheet ingot 53 in the mold 54 installed on the pallet 55, the mold 54 together with the pallet 55 and the carriage 56 makes a reciprocating movement relative to the electrodes 52. In the same mold 54, multilayer ingots can be obtained. For this, it is necessary that the consumable electrodes are made out of height from different materials. Claims The device for electroslag overlap, containing a three-column three-phase furnace with tilt-and-slide electrode holders, is characterized in that, in order to mobility of electrode melting in different modes of different crygaplock jams, as well as smelting capabilities. different in weight and purpose, it is additionally equipped with a two-column single-phase furnace with an electrode holder moving in a vertical plane, while the vertical axes of the columns of a two-column stove and the axis of one or more columns of a three-column furnace are in the same plane, and the distance between adjacent columns Furnaces do not exceed the maximum electrodescapacity; FIG.
