Embodiment Construction

[0031] The present invention is achieved through the following technical solutions, a propeller rapid prototyping process, which comprises the following steps:

[0032] 1) Copper alloy smelting

[0033] a). Rough smelting, put the copper alloy into the melting furnace to heat and melt; at the same time, place a nitrogen blowing device on the upper side of the melting furnace to isolate the air from the melting liquid;

[0034] b). Refining. After rough refining, cryolite powder is added to the metal solution; at the same time, the melting furnace is heated to 1000 degrees for half an hour, and a copper alloy refining slag remover with a mass fraction of 0.4% is added during the process;

[0035] Among them, cryolite powder helps to dissolve metal oxides containing magnesium and aluminum, and reduces the existence of insoluble matter in the solution.

[0036] 2) Pouring

[0037] c). Inject the refined copper alloy metal solution into the pouring system; the pouring system ado...

Description

technical field [0001] The invention relates to the technical field of propeller manufacturing, in particular to a rapid prototyping process for propellers. Background technique [0002] The propeller is the main component that provides power for the hull. At present, the propeller is driven by the main engine. The quality of the propeller is directly related to the sailing performance of the ship. The current propeller casting cycle is long, there are many processes, and the product quality is not good. Contents of the invention [0003] The present invention is proposed in view of the above-mentioned problems existing in the prior art, and the present invention provides a propeller rapid prototyping process. The present invention is achieved through the following technical solutions, a propeller rapid prototyping process, which comprises the following steps: [0004] 1) Copper alloy smelting [0005] a). Rough smelting, put the copper alloy into the melting furnace to...
