Copper plate of crystallizer of high-efficiency continuous casting machine

Abstract

The invention discloses a copper plate of a crystallizer of a high-efficiency continuous casting machine. The copper plate comprises a copper plate body and a plurality of transverse cooling channelslongitudinally formed in the copper plate body at intervals; each transverse cooling channel comprises a transverse cold water hole transversely drilled in the copper plate body, a middle water hole formed in the middle of a cold surface, side water holes formed in the cold surface and located on two sides of the middle water hole as well as screw plugs fixed to the end openings of the transversecold water hole in a sealed manner, and the middle water hole and the side water holes communicate with the transverse cold water hole. According to the copper plate, the transverse cooling mode is adopted, uniform cooling is realized with the mode, with increase of the water inlet and outlet holes, the flow of cooling water can be substantially increased, the cooling effect can be improved, and essential conditions for the high casting speed can be realized.

Description

technical field

[0001] The invention belongs to the technical field of continuous casting machines for steelmaking, in particular to a high-efficiency continuous casting machine crystallizer copper plate. Background technique

[0002] The mold is the heart of the continuous casting machine. Its structural design will directly affect the casting speed and quality of the slab. It is the key technology in the modern steelmaking and continuous casting production.

[0003] The mold can be divided into five categories according to the shape of the billet produced: square billet mold, rectangular billet mold, round billet mold, slab mold and special-shaped billet mold. According to the cooling method, it can be divided into: water jacket and copper Tube assembly type (mainly used for tube molds of square billets, round billets and rectangular billets), spray type (mainly used for tube molds), copper plate or copper tube cold surface open water tank type, copper plate or copper tube...

Examples

Embodiment 1

[0049] like figure 1 and 2 As shown, a high-efficiency continuous casting machine crystallizer copper plate includes a copper plate body 1 and several transverse cooling channels longitudinally spaced inside the copper plate body 1;

[0050] The copper plate body 1 has a cold surface 3 and a hot surface 2 on the opposite side of the cold surface 3;

[0051] Each of the transverse cooling passages includes a transverse cold water hole 4 drilled transversely in the copper plate body 1, a middle water hole 5 set in the middle of the cold surface 3, and a side hole 5 set on the cold surface 3 and located on both sides of the middle water hole 5. The external water hole 6 and the plug 8 sealed and fixed at the port of the transverse cold water hole 4;

[0052] Both the central water hole 5 and the side water hole 6 communicate with the lateral cold water hole 4 .

[0053] Further, the cross-sectional area of ​​the central water hole 5 is equal to the sum of the cross-sectional a...

Embodiment 2

[0060] like image 3 and 4 As shown, the difference between this embodiment and the first embodiment is that the hot surface 2 of the copper plate body 1 is an outer arc surface.

Embodiment 3

[0062] like Figure 5 and 6 As shown, the difference between this embodiment and the second embodiment is that the hot surface 2 and the cold surface 3 of the copper plate body 1 are both straight surfaces,

[0063] The sides of the two copper plate bodies 1 with the ports of the transverse cold water holes 4 are curved surfaces.
