Embodiment 1
[0029] Such as figure 1 The smelting equipment for zinc alloy shown is composed of vacuum smelting equipment with built-in air passage and graphite stirring device and melting crucible 1, a protective atmosphere furnace, and a graphite crucible with mechanical stirring device, wherein the inner surface of melting crucible 1 The filter structure 2 is fixed in the area from the bottom to the top of the side 4 of the inner surface according to the structure of the wave wheel washing machine. The filter structure 2 is specifically composed of alumina ceramic wedges, alumina ceramic outer frame, and a primary coarse screen Net 5, and the online filter screen 3 made of carbon fiber ceramic composite material lined on the outer surface of the primary coarse screen 5;
[0030] Wherein the manufacture method of online filter screen cloth 3 is:
[0031] ①Material preparation: Prepare enough ammonia gas, enough propane, enough acrylonitrile, enough polyethylene oxide, enough pure water,...
Embodiment 2
[0043] The whole is consistent with Example 1, the difference is:
[0044] The basic salt used is specifically Cu 2 (OH) 2 CO 3 .
Embodiment 3
[0046] Such as image 3 The smelting equipment of a kind of zinc alloy shown is consistent with the embodiment 1 as a whole, the difference is that: the inner surface side 4 bottom to the top area of the inner surface of the smelting crucible 1 is fixed according to the structure of the wave wheel washing machine to set the filter net. Two filter structures 2 are provided, and the normal line of the opening end surface of the online filter screen 3 integrated on the two filter structures 2 faces the same direction and the two normal lines are parallel; the filter structure 2 is specifically composed of alumina ceramic wedges, alumina ceramic The outer frame, the primary coarse screen 5 made of alumina ceramics, and the online filter screen 3 made of carbon fiber ceramic composite material lined on the outer surface of the primary coarse screen 5 are formed.
[0047] The high aluminum-zinc alloy with 25%-28% aluminum mass fraction smelted in the present invention has a tensil...
