Embodiment 1
[0035] combine Figure 1-4 , the device for improving the castability of the microalloy steel continuous casting process in this embodiment includes a pouring mechanism and an electrode clamping mechanism.
[0036] The pouring mechanism includes a ladle 11 and a tundish 13. The ladle 11 is placed above the tundish 13. The interior of the ladle 11 communicates with the interior of the tundish 13 through the long nozzle 12; Used in conjunction with the stopper rod 10 , a retaining wall 15 and a retaining dam 16 are provided between the submerged nozzle 14 and the shroud 12 inside the tundish 13 .
[0037]The electrode clamping mechanism includes: a cylindrical pulse electrode 1, when the micro-alloy steel slab is poured by the continuous casting process, the pulse electrode 1 is placed in the micro-alloy molten steel in the tundish 13 and applies a pulse current to the micro-alloy molten steel; Holder 2, clamping piece 2 is used to clamp pulse electrode 1; energizing piece 3, o...
Embodiment 2
[0050] to combine Figure 2-4 , the device for improving the castability of the microalloy steel continuous casting process in this embodiment has basically the same structure as in Embodiment 1, and further: the clamping part 2 includes two semicircular rings with folded edges, and two folded rings The circular arc part of the semicircular ring on the edge forms a clamping ring 201, and the clamping ring 201 is wrapped around the outer surface of the pulse electrode 1, and the corresponding flanged parts of the two semicircular rings with flanges are connected by the first bolt 7 , forming a clamping piece 202 .
[0051] In this embodiment, the clamping member 2 includes two semicircular rings with folded edges, and the circular arc parts of the two semicircular rings with folded edges form a clamping ring 201, and the clamping ring 201 is wrapped around the pulse electrode 1. The outer side of the two semicircular rings with hemming are connected by the first bolt 7 to form...
Embodiment 3
[0053] to combine Figure 2-4 The structure of the device for improving the castability of the microalloy steel continuous casting process of this embodiment is basically the same as that of Embodiment 2, and further: the energizing member 3 includes a energizing rod 301 and connecting pieces 302 connected to both ends of the energizing rod 301; The connecting piece 302 at one end of the power pole 301 is connected to a clamping piece 202 of the clamping member 2 through the second bolt 8 .
[0054] In this embodiment, the energizing member 3 includes a energizing rod 301 and a connecting piece 302 connected to both ends of the energizing rod 301, and the connecting piece 302 at one end of the energizing rod 301 is connected to a clamping piece 202 of the clamping member 2 through a second bolt 8 , so that the installation between the power pole 301 and the clamping member 2 is convenient, and it is convenient for on-site use.
