Embodiment 1

[0021] see Figure 1-3 , the present embodiment includes a mold body, the mold body is provided with a copper pouring cavity, and the mold body is located at the upper part of the copper pouring cavity and is provided with a top mold hole for lifting the mold, and the mold body is also provided with several holes in the copper pouring cavity. Anchor hole, a layer of chromium-zirconium-copper alloy is fixed through the anchor hole in the copper-casting cavity, and the chemical composition weight percentage of the chromium-zirconium-copper alloy is: Cr:0.75, Zr:0.15, Mn<0.0013, Mo<0.0003, Ni <0.0005, Fe<0.037, the balance is Cu.

[0022] The middle section of the top of the phantom described in this embodiment is provided with two symmetrically arranged grooves, forming a mountain-shaped surrounding structure.

[0023] The anchor holes described in this embodiment are provided with at least four, forming a rectangle.

[0024] The material of the mold body described in this emb...

Embodiment 2

[0027] The structure of this embodiment is basically the same as that of Embodiment 1. The difference is that the chemical composition weight percentage of the chromium-zirconium-copper alloy is: Cr: 0.85, Zr: 0.25, Mn<0.0013, Mo<0.0003, Ni<0.0005, Fe<0.037 , the balance being Cu.

Embodiment 3

[0029] The structure of this embodiment is basically the same as that of Embodiment 1. The difference is that the chemical composition weight percentage of the chromium-zirconium-copper alloy is: Cr:0.8, Zr:0.2, Mn<0.0013, Mo<0.0003, Ni<0.0005, Fe<0.037 , the balance being Cu.

Abstract

The invention relates to the technical field of mold production in the metallurgical industry, in particular to a composite copper anode mold with improved service life, which includes a mold body on which a copper pouring cavity is opened, and the mold body is located on the upper part of the copper pouring cavity and is provided with a mold lifter The top mold hole, the mold body is located in the copper pouring cavity and is compounded with a layer of chromium-zirconium-copper alloy. The chemical composition weight percentage of the chromium-zirconium-copper alloy is: Cr:0.75-0.85, Zr:0.15-0.25, Mn< 0.0013, Mo<0.0003, Ni<0.0005, Fe<0.037, and the balance is Cu; the service life of the copper anode mold of the present invention is greatly extended, and the average copper pouring amount can reach more than 1000 tons / block.

Description

technical field [0001] The invention relates to the technical field of mold production in the metallurgical industry, in particular to a composite copper anode mold with improved service life and a production method thereof. Background technique [0002] The copper anode mold is the mold for casting copper anode plates in copper smelters. It is the main consumable auxiliary material in copper smelting production. The service life of copper anode molds directly affects the smelting cost of copper smelters and the labor intensity of operators. [0003] The working environment of the copper anode mold is very harsh. It not only has to withstand the erosion of copper water above 1200 ℃, but also has to withstand the cooling of cold water below 30 ℃. [0004] The existing copper anode mold is made of single gray cast iron or anode copper. The copper anode mold made of gray cast iron has low mechanical strength and low thermal fatigue resistance, and is prone to cracks or cracks ...
