Continuous casting copper mold plate and continuous casting copper mold formed therefrom

Abstract

This invention provides a continuous casting copper template and a continuous casting copper mold assembled therefrom. The continuous casting copper template has an inner surface and an outer surface. The inner surface defines a casting cavity, wherein the inner surface includes a flat portion and chamfered portions located at both ends of the flat portion, the chamfered portions being connected to the flat portion to form a continuous inner wall surface. The outer surface is provided with multiple cooling channels. The bevel width of the chamfered portion is 25 to 35 mm.

Claims

1. A continuous casting copper template, comprising: an inner surface for defining a casting cavity, wherein the inner surface includes a flat portion and chamfered portions located at both ends of the flat portion, the chamfered portions being connected to the flat portion to form a continuous inner wall surface of the casting cavity; and an outer surface, wherein the outer surface is provided with a plurality of cooling channels; wherein, The bevel width of the chamfered portion is 25 to 35 mm.

2. The continuous casting copper template as described in claim 1, wherein the angle formed by the chamfered portion and the extension line of the surface of the planar portion is 32 degrees.

3. The continuous casting copper template as described in claim 1, wherein the outer side is provided with a plurality of parallel cooling channels at a position corresponding to the planar portion, the parallel cooling channels extending along a thickness direction from the outer side to the inner side.

4. The continuous casting copper template as described in claim 3, wherein a through cooling channel is provided on the outer side corresponding to the chamfered portion, and the through cooling channel extends along the continuous casting direction of the continuous casting copper template.

5. The continuous casting copper template as described in claim 4, wherein the parallel cooling channel and the through cooling channel are interconnected through a guide branch.

6. The continuous casting copper template as described in claim 4, wherein a V-shaped cooling channel is provided on the outer side corresponding to the position between the flat portion and the chamfered portion, and is interconnected with the parallel cooling channel and the through cooling channel through a guide branch.

7. The continuous casting copper template as described in claim 6, wherein the V-shaped cooling channel is V-shaped in cross-section and its opening faces the chamfered portion.

8. The continuous casting copper template as described in claim 1, wherein the chamfered portion protrudes toward the casting cavity along the direction of extension of the planar portion to form a chamfered bevel.

9. A continuous casting copper mold comprising four copper templates, wherein at least two of them are continuous casting copper templates as described in any one of claims 1 to 8, the copper templates being combined with each other to define a casting cavity having a rectangular cross-section with chamfered corners.

10. The continuous casting copper mold as claimed in claim 9, wherein the cooling channel of the continuous casting copper mold is connected to a cooling device for circulating cooling medium.
