Description
Известны способы получени магниевых сплавов с редкоземельными металлами путем введени последних в магний из лигатур или чистых металлов.Methods are known for the production of magnesium alloys with rare earth metals by introducing the latter into magnesium from master alloys or pure metals.
Предложенный способ позвол ет снизить стоимость магниевых сплавов с редкоземельными металлами не менее чем в два раза, сократить цикл производства за счет исключени процессов получени металлургических лигатур типа магний - редкоземельный металл и устранить р д трудоемких и дорогосто щих операций, таких как электролитическое получение лигатур. Эти преимущества достигаютс вследствие того, что редкоземельные металлы ввод т в сплав из смеси солей , содержащих фторид редкоземельных металлов и хлориды щелочных металлов. Применение флюсов, не содержащих химически активную по отнощению к редкоземельным металлам соль MgCla, такнсе позвол ет сократить потери дорогосто щих металлов.The proposed method allows reducing the cost of magnesium alloys with rare earth metals by no less than two times, reducing the production cycle by eliminating processes for producing metallurgical master alloys of magnesium — a rare earth metal and eliminating a number of laborious and expensive operations, such as electrolytic production of master alloys. These advantages are achieved due to the fact that rare earth metals are introduced into the alloy from a mixture of salts containing rare earth fluoride and alkali metal chlorides. The use of fluxes that do not contain the salt MgCla, which is chemically active with respect to rare earth metals, also reduces the loss of expensive metals.
Технологи получени магниевых сплавов по предложенному способу заключаетс в следующем. В расплавленный магний при 700- 800° ввод т редкоземельные металлы из сплава солей одного из следующих составов:The technology for producing magnesium alloys according to the proposed method is as follows. Rare earth metals from an alloy of salts of one of the following compositions are introduced into molten magnesium at 700-800 °:
1)50-65% фторидов редкоземельных металлов, 20-30% хлористого кали , 15-20% хлористого натри и 1-2% фтористого кальци .1) 50-65% rare earth fluorides, 20-30% potassium chloride, 15-20% sodium chloride and 1-2% calcium fluoride.
2)50-75% фторидов редкоземельных металлов. 20-30% хлористого лити и 8-1В% фтористого кали .2) 50-75% of rare-earth fluorides. 20-30% lithium chloride and 8-1B% potassium fluoride.
Чистота солей может составл ть 90%. Фтористые соли ввод т в расплав порци ми при тщательном перемещивании, после чего расплав выдерживают 10-30 мин и затем разливают в чущки. ПлавкуThe purity of the salts may be 90%. Fluoride salts are introduced into the melt in portions with careful transfer, after which the melt is kept for 10-30 minutes and then poured into bits. Fusion
№ 141630- 2 ведут под слоем флюса одного из следующих составов; 1) 47-51% СаСЬ; 26-29% ВаСЬ; 19-21% NaCl и 2-5% СаРг. 2) 35-39% СаСЬ; 22-26% КС1; 19-24.%ВаС1; 17-20% NaCl и 2-5% CaFj.No. 141630-2 are carried out under a flux layer of one of the following compositions; 1) 47-51% CAL; 26-29% YOU; 19-21% NaCl and 2-5% CaPg. 2) 35-39% CAC; 22-26% KC1; 19-24.% BaCl; 17-20% NaCl and 2-5% CaFj.
Усвоение редкоземельных металлов, вводимых из расплава солей, составл ет.65-80 %.The absorption of rare earth metals introduced from the molten salt is 65-80%.
