Problems solved by technology

Because the inner hole of the mold has a certain taper, the aspect ratio of the electroslag ingot is limited. The longer the electroslag ingot, the longer the cone will be, and the difficulty of demoulding will increase.
At the same time, when the consumable electrode is remelted in the inner cone mold, the filling ratio of the electrode rod in different sections of the mold changes, so the process parameters need to change continuously, and the adjustment and control of the remelting parameters is an unstable process, and there is a phenomenon of inconsistency in the size of the core structure of the steel ingot
[0003] When the frustum-shaped steel ingot formed by the traditional inner conical crystallizer is subjected to subsequent pressure processing, such as forging process, due to the taper of the steel ingot, the force on the large and small heads within the length of an upper anvil is uneven, which is easy to make the internal structure of different cross-sections Uneven crushing leads to poor organizational consistency and uneven stress on the equipment, and the resulting impact load affects the stability of equipment operation

Embodiment 1

[0026] This embodiment relates to a split crystallizer for electroslag remelting of steel ingots with equal diameters, such as figure 1 As shown, it includes two symmetrically arranged first water-cooling jackets 1 and second water-cooling jackets 2 with semi-cylindrical cavities. The connected water inlet pipe 3 and the water outlet pipe 4 are provided with a positioning connection device 5 on one side of the two water cooling jackets, and a locking device 6 is also provided on the other side of the two water cooling jackets relative to the positioning connection device 5 .

[0027] The structure of the first water cooling jacket 1 is as follows: figure 2 As shown, a semi-cylindrical cavity is formed by a semicircular inner shell 8. The outer shell 9 surrounds the outside of the inner shell 8. The upper and lower end faces of the inner shell 8 and the outer shell 9 are connected together by a transverse connecting plate 10. The inner shell 8 The side end of the outer shell ...

Embodiment 2

[0034] This embodiment relates to a split crystallizer for equal-diameter electroslag remelting, which has roughly the same structure as the split crystallizer in Embodiment 1, except that the first water cooling jacket 1 in this embodiment structured as Figure 8 As shown, three first connecting lugs 54 with mounting shafts 55 are equidistantly arranged at the edge of one side thereof, and the mounting shafts 55 can pass through the connecting holes 52 on the connecting lugs 51 on the second water cooling jacket 2 , to achieve the same connection function as the connection pin 53, and the connection operation of the water cooling jacket is more convenient.

Abstract

The invention relates to a split crystallizer for electroslag remelting of equal-diameter steel ingots, which includes two symmetrically arranged water-cooling jackets with semi-cylindrical cavities, and a positioning and connecting device is arranged on one side of the two water-cooling jackets. The above-mentioned positioning and connecting device makes the two water-cooling jackets have a connection between the two water-cooling jackets when they are rotated and fitted, and the inner cavity of the crystallizer is a cylindrical connection with the same diameter up and down; on the other side of the two water-cooling jackets relative to the positioning and connecting device There is also a locking device for locking the two fitted water cooling jackets. The split crystallizer of the present invention realizes electroslag remelting of steel ingots with equal diameters, has a stable process, and has a simple demoulding method, is convenient to use, and is beneficial to the subsequent processing of steel ingots.

Description

technical field [0001] The invention relates to a crystallizer for electroslag remelting, in particular to a split crystallizer for electroslag remelting of steel ingots with equal diameters. Background technique [0002] The crystallizer for metallurgical electroslag remelting generally adopts a water-cooled jacket structure with an overall conical inner hole, and the taper range is generally between 1:26 and 1:50 to ensure smooth demolding of the electroslag ingot after solidification. Since the inner hole of the crystallizer has a certain taper, the length-to-diameter ratio of the electroslag ingot is limited. The longer the electroslag ingot, the longer the cone will be, and the difficulty of demoulding will increase. At the same time, when the consumable electrode is remelted in the inner cone mold, the filling ratio of the electrode rod in different sections of the mold changes, so the process parameters need to change continuously, and the adjustment and control of th...
