Embodiment 1

[0043] refer to figure 1 with figure 2, a multilayer composite copper plate used for the wide face of a slab continuous casting machine crystallizer, comprising at least one rectangular multilayer composite copper plate, is characterized in that: the multilayer composite copper plate is composed of a three-layer structure, from top to bottom The bottom is respectively the second coating layer 5, the first coating layer 4 and the multilayer composite copper plate body 1. Several rows of parallel protrusions are arranged on the lower surface of the multilayer composite copper plate body 1, and bolt holes are opened on the plurality of parallel rows of protrusions. 2. Bolts are connected in the bolt holes 2, and cooling water tanks 3 in the same direction as the protrusions are arranged in the grooves formed between two adjacent rows of parallel protrusions.

[0044] In actual use: By setting the multi-layer composite copper plate into a three-layer structure, the heat transfer...

Embodiment 2

[0046] Compared with Embodiment 1, the difference of this embodiment is that: four cooling water grooves 3 in the same direction as the protrusions are arranged in the grooves formed between two adjacent rows of parallel protrusions, and four cooling water grooves 3 The middle two are parallel to the raised water tanks, and the two adjacent to the middle two cooling water tanks 3 are inclined water tanks, the bottom of the inclined water tanks is inclined to the direction of the protrusion with the bolt hole 2, and the center of the inclined water tank and the bolt hole 2 The angle between the lines is α.

[0047] In actual use: four cooling water tanks 3 are provided, and the middle two of the four cooling water tanks 3 are water tanks parallel to the protrusions to increase the cooling effect and make the cooling effect better. The two adjacent to the middle two cooling water tanks 3 are The inclined water tank, the bottom of the inclined water tank is inclined to the direct...

Embodiment 3

[0049] Compared with Embodiment 2, the difference of this embodiment is that: the angle α between the inclined water tank and the center line of the bolt hole 2 is 12°-15°;

[0050] Preferably, the angle α between the inclined water tank and the centerline of the bolt hole 2 is 14°;

[0051] Preferably, the middle two are parallel to the width c of the raised water tank 2 18mm, depth h 2 is 6mm, and the width of the two inclined water grooves adjacent to the middle two cooling water grooves 3 is c 1 5mm, depth h 1 is 11mm.

[0052] In actual use: the angle α between the inclined water tank and the centerline of the bolt hole 2 is 12°~15°, and the angle α between the inclined water tank and the centerline of the bolt hole 2 is preferably 14°. By setting the angle α between the inclined water tank and the bolt hole 2 The included angle between the centerlines of holes 2 is used to further cool the copper plate around the bolts to ensure that the temperature of the entire mul...

Abstract

The invention relates to the field of metallurgical continuous casting equipment, in particular to a multi-layer composite copper plate used for slab continuous casting machine crystallizer wide surface and preparing method thereof. The multi-layer composite copper plate is arranged to be of a three-layer structure, on the basis that the heat transfer efficiency is not reduced, the uniformity of heat transfer of a copper plate fracture surface in the cast slab width direction is ensured, and the problem about the surface quality of a cast slab is avoided while the service life of the copper plate is prolonged. A plurality of rows of parallel protrusions are arranged on one side of the multi-layer composite copper plate, the multiple rows of parallel protrusions are provided with bolt holes, bolts are connected into the bolt holes, cooling water tanks are formed at the positions, between two adjacent rows of parallel protrusions, on a multi-layer composite copper plate body, the thickness of the parts, provided with the protrusions, of the overall multi-layer composite copper plate body is larger than the thickness of the parts provided with the water tanks, the distances between the upper edges of the bolts in the bolt holes and the upper surface of the multi-layer composite copper plate are increased, and the influence of the bolts on the surface temperature of the multilayercomposite copper plate is reduced conveniently.

Description

[0001] Technical field [0002] The invention relates to the field of metallurgical continuous casting equipment, in particular to a multi-layer composite copper plate used for the wide surface of a crystallizer of a slab continuous casting machine and a preparation method thereof. Background technique [0003] In the continuous casting process, the solidified slab shell is initially formed in the mold. The copper plate in the mold cools the molten steel on the one hand, and acts as a mold for the solidification of the molten steel on the other hand. uniformity of heat. If the heat transfer from the shell to the crystallizer is not uniform, it may cause surface cracks, depressions and other defects. The properties of the mold slag between the billet and the copper plate, the material of the copper plate and the arrangement of the water joints in the copper plate have an important influence on the heat transfer of the billet shell. [0004] In recent years, with the developme...
