“Different aluminum degassing effects by using different inert gases”<\/h1>\n

\"aluminum<\/p>\n

 <\/p>\n

There are different aluminum degassing effects during the high-temperature smelting process of aluminum and its alloys in the horno de fundici\u00f3n de aluminio<\/a>, the influence of pure metal ingots, intermediate alloys, scraps, high-temperature furnace gas, refractory materials, and tools on the purity of aluminum melts causes the ingots to produce pores and slag inclusions and other metallurgical processes defect. Therefore, in the production process, refining with flux and inert gas is used to reduce the generation of metallurgical defects. However, the refining treatment in the furnace has the following problems:<\/p>\n

Different aluminum degassing effects by different insert gases<\/p>\n

(1) The refining flow of pure inert gas is large, the bubbles are large, the melt is tumbling seriously, and it is easy to oxidize and form slag, and the degassing effect is good, but the slag removal effect is poor; and the cost of large flow argon is high, and MgN and AlN are easily generated with nitrogen. , the degree of purification is poor.
\n(2) The toxicity and activity of chlorine purification are high, the reaction is too intense, the harm is many, and the purification effect is even worse.
\n(3) Mixed gas refining Using nitrogen and chlorine gas or argon and chlorine gas mixture for refining, the purification effect is not obvious, it is harmful to human health, and it seriously corroded the surrounding equipment.
\n(4) Although pure flux purification can better remove oxidized slag inclusions, and can also remove some gases, it is not thorough and will also bring flux slag inclusions.
\n(5) The degassing effect of vacuum treatment is very good, but the effect of removing impurities is very small, and the cost of equipment and operation is expensive.<\/p>\n

To sum up, the most economical, practical, and effective in-furnace powder spray refining flux purification effect and gas purification effect is the most effective refining method for aluminum alloy melts \u00a8J. However, the hydrogen content of the aluminum melt in the smelting furnace is all o. Between 24 mL\/100 g and 3.0 mL\/100 g,
\nIn order to make the ingot not meet the usual quality requirements, it must be further purified; therefore, the online degassing unit and filtration purification treatment technology outside the furnace is developed. This article focuses on the progress of the online degassing process technology from unidad de desgasificaci\u00f3n<\/a>s.<\/p>","protected":false},"excerpt":{"rendered":"
