Embodiment 1
[0020] The chemical analysis of electrolytic copper, electrolytic nickel, industrial pure aluminum, industrial pure zinc, crystalline silicon and iron nails is carried out. Firstly, the electrolytic copper and industrial pure zinc are smelted in an intermediate frequency induction furnace according to the mass percentage of 4:1. Copper is used as the master alloy for smelting DH copper alloy in the next step. Prepare the tested master alloy, electrolytic nickel, industrial pure aluminum, crystalline silicon and iron nails according to the ratio of: Ni15%, Al8%, Zn9%, Si1.0%, Mn0.2%, Fe<0.15%, and the rest For Cu and unavoidable impurities. Then put the industrial pure aluminum weighed according to the ratio into the intermediate frequency furnace, wait until the industrial pure aluminum is basically dissolved, then put the electrolytic nickel, wait until the above furnace materials are basically melted, then put the electrolytic copper, crystalline silicon and iron nails Put ...

[0022] The charge is weighed according to the following mass percentages: Ni16%, Al10%, Zn10%, Si1.1%, Mn0.2%, Fe<0.15%, and the rest is Cu and unavoidable impurities. The preparation method is the same as in Example 1. Impurities need to be controlled in the finished product: P<0.01%, S<0.01%.
Embodiment 3
[0024] The charge is weighed according to the following mass percentages: Ni14%, Al8%, Zn8%, Si0.9%, Mn0.1%, Fe<0.15%, and the rest is Cu and unavoidable impurities. The preparation method is the same as in Example 1. Impurities need to be controlled in the finished product: P<0.01%, S<0.01%.
[0025] The material composition of the DH copper alloy glass mold die of the present invention is complex white copper, containing Ni, Al, Zn and other elements, and the melting point difference between the alloy elements is large. This problem is well solved by the secondary smelting method, and it can be melted in time. Pre-control the composition of the alloy material. Due to the strong oxidation ability of the copper alloy, the solidification shrinkage is relatively large. The deoxidation and slag removal technology in the ladle greatly reduces the oxidation slag inclusion of DH copper alloy, and the special pouring system is designed by ourselves to solve the problem of shrinkage...
