Problems solved by technology

[0004] The existing aluminum-titanium-boron alloy production process is mainly produced by the fluoride salt method, mainly adding the mixture of potassium fluoroborate and potassium fluorotitanate to the aluminum body at 750-850 ° C, so that Ti and B elements are separated from the fluoride salt compound During the reaction process, a large amount of liquid slag is produced. Its density is lower than that of molten aluminum, and it floats on the upper layer of molten aluminum, and has excellent fluidity, which is convenient for pouring out of molten aluminum. However, due to its excellent affinity with aluminum It is extremely difficult to remove the wettability of aluminum-titanium-boron alloys, and the temperature is generally controlled at 800-880°C during the refining of aluminum-titanium-boron alloys, which exceeds the use temperature of ordinary slagging agents.

Abstract

The invention relates to the field of refining of intermediate alloy of aluminum, in particular to a special high-temperature slag forming agent for refining an aluminum titanium boron alloy. The special high-temperature slag forming agent comprises the following components in parts by weight: 13-18 parts of MgF2, 22-27 parts of NaF; 16-25 parts of Na3AlF6, 20-28 parts of CaF2, and 12-15 parts of Na2SiF6. Through the utilization of the slag forming agent disclosed by the invention, fluorides and oxides in the aluminum titanium boron alloy can be well removed, and the slag forming effect is good, so that the content of impurities in the alloy can be greatly reduced, the cleanliness and the quality of the alloy are improved, and the refining ability of the aluminum titanium boron alloy is improved; and besides, the price of the slag forming agent disclosed by the invention is nearly equal to that of a common slag forming agent, so that no extra expenses are not additionally generated.

Description

[0001] (1) Technical field [0002] The invention relates to the field of refining aluminum master alloys, in particular to a high-temperature slagging agent specially used for refining aluminum-titanium-boron alloys. [0003] (2) Background technology [0004] The existing aluminum-titanium-boron alloy production process is mainly produced by the fluoride salt method, mainly adding the mixture of potassium fluoroborate and potassium fluorotitanate to the aluminum body at 750-850 ° C, so that Ti and B elements are separated from the fluoride salt compound During the reaction process, a large amount of liquid slag is produced. Its density is lower than that of molten aluminum, and it floats on the upper layer of molten aluminum, and has excellent fluidity, which is convenient for pouring out of molten aluminum. However, due to its excellent affinity with aluminum It is very difficult to clean the wettability of the aluminum-titanium-boron alloy, and the temperature is generally ...
