Embodiment 1

[0011] An aluminum-titanium alloy AlTi 10 The specific production process is as follows: (1) put the aluminum ingot with a content greater than 99.70% into the electric furnace, and slowly raise the temperature until the aluminum ingot is completely melted; (2) continue to heat up to 1250°C, and then add the aluminum ingot with a content greater than 99.98% until the sponge titanium is completely melted, the mass ratio of aluminum ingot to titanium sponge is 100:11; (3) Stir the alloy liquid with a magnetic stirrer for 20 minutes; (5) After the reaction, add a homogenizing agent before sampling and carry out static reaction for 1520 minutes, then perform low-magnification analysis and component analysis; (6) After passing the inspection, cast the alloy liquid.

Embodiment 2

[0013] An aluminum-titanium alloy AlTi 10 The specific production process is as follows: (1) put the aluminum ingot with a content greater than 99.70% into the electric furnace, and slowly heat up until the aluminum ingot is completely melted; (2) continue to heat up to 1250°C, and then add the aluminum ingot with a content greater than 90% until the titanium chips are completely melted, the mass ratio of aluminum ingots to titanium chips is 100:11; (3) Stir the alloy liquid for 20 minutes with a magnetic stirrer; (5) After the reaction, add a homogenizing agent before sampling and carry out static reaction for 1520 minutes, then perform low-magnification analysis and component analysis; (6) After passing the inspection, cast the alloy liquid.

[0014] The advantages of the production process of the present invention: the electric furnace is a high-consumption equipment, and this process adopts low-power operation (8-12h electricity cost 1.38 yuan / h, 12-17h electricity cost 0....

Abstract

The invention discloses a production process of aluminum-titanium alloy AlTi10. The production process comprises the steps of placing an aluminum ingot with the content of larger than 99.70% into an electric furnace, and heating to 1250 DEG C; adding sponge titanium or titanium scraps until the aluminum ingot is completely molten, wherein the mass ratio of the aluminum ingot to the sponge titanium or the titanium scraps is 100:11; uniformly stirring through a magnetic stirrer; adding lithium aluminum tetrahydride, and standing for reacting; adding a leveling agent to stand before sampling, and then, carrying out low-power analysis and component analysis; and casting and molding after the assay is approved. Power low-ebb operation is adopted in the production process disclosed by the invention, so that energy sources are saved, and the production cost is reduced; manpower work can be replaced with magnetic stirring equipment, so that materials can be sufficiently and uniformly stirred, the labor intensity of a worker can be reduced, the production period can be shortened, and the production efficiency can be increased; and the titanium content of the casting product AlTi10 can be up to 9-11% which is twice as much as the content of titanium produced by using the old national standard, and no segregation is caused.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy production, in particular to an aluminum-titanium alloy AlTi 10 production process. Background technique [0002] At present, the national standard aluminum-titanium alloy on the market is only AlTi 5 , and the production process of this aluminum-titanium alloy is old, the process is as follows: add aluminum ingot (content>99.70%) and sponge titanium (content>99.98%) into the electric furnace according to the mass ratio of 100:11, first add aluminum ingot , and then heated to the smelting temperature of adding titanium and then adding titanium sponge. At this time, artificial stirring was used, and the stirring was fully uniform. Finally, low-power analysis was carried out. After passing the inspection, the casting operation was carried out. This production process is outdated, consumes a lot of electric energy, and the production cost is high. Moreover, manual stirring is used, whi...
