Embodiment Construction
[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0029] As shown in the accompanying drawings, the pipe mold powder preparation process of the present invention adopts a fusion method, and its specific steps are: batching, smelting, pouring, cooling, crushing, powder making, mixing according to particle size distribution, and vacuum packaging.
[0030] Further, scrap steel, ferrosilicon, silicon calcium, silicon barium, ferromanganese, pure magnesium ingot and pure aluminum ingot are used as raw materials in the batching step, and the batching is designed according to the composition content of the pipe mold powder with reference to the burning loss rate; intermediate frequency is used for melting Induction electric furnace, according to the order of steel scrap, ferrosilicon and calcium silicon, add ferromanganese, metal magnesium and metal aluminum before pouring; in the pouring step, after the alloy...
