[0021] The technical solutions of the present invention are further described below, but the claimed scope is not limited to the description.
[0022] like figure 1 As shown, the present invention provides a carbon-containing alloy material investment casting process, comprising the following steps:
[0023] Provide a work platform 1, prepare a mold shell 2 according to the shape of the design in the pre-drawn design drawings, prepare a protective cover 3 according to the shape of the mold shell 2, cover the protective cover 3 on the work platform 1 to form a closed space, and enter the mold shell 2. The carbon-containing alloy material 4 in a liquid state is poured and smelted, and then the mold shell 2 is transferred into a closed space, and the liquid-state carbon-containing alloy material 4 is condensed into a solid in the closed space to obtain a casting.
[0024] Further, the material of the protective cover 3 is preferably stainless steel. The wall thickness of the pr...
