Description
Изобретение относитс к области цветной металлургии, в частности к разработке технологии выплавки алюминиево-циркониевой лигатуры .The invention relates to the field of non-ferrous metallurgy, in particular to the development of the technology for smelting aluminum zirconium master alloy.
Известен способ получени алюминиеводмркониевой лигатуры введением в расплавленный алюминий солевого сплава, содержащего фторцирконат кали , хлористый литий и фторид кальци , полученного сплавлением солей . Этот способ имеет следующие недостатки: плавление солей вл етс т желой операцией , занимающей 4-6 час, кроме того, смесь солей необходимо измельчать, на что затрачиваетс 1-2 час, а дл получени из солей необходимой лигатуры требуетс 3-4 час. Таким образом, продолжительность известного способа составл ет 8-12 час.. Кроме того, используют дорогосто щее сырье.A method is known for producing an aluminum-water-based ligature by introducing into the molten aluminum a salt alloy containing potassium fluorocirconate, lithium chloride, and calcium fluoride obtained by fusing salts. This method has the following disadvantages: the melting of salts is a heavy operation, which takes 4-6 hours, in addition, the salt mixture must be crushed, which takes 1-2 hours, and it takes 3-4 hours to obtain the necessary ligature from the salts. Thus, the duration of the known method is 8-12 hours. In addition, expensive raw materials are used.
По предлагаемому способу в качестве цирконийсодержащего материала используют циркониевый концентрат, который ввод т порци ми в расплавленный при 1000-1100°С под слоем криолита алюминий, и расплав тщ.ательно перемешивают, причем криолит берут в количестве 6-8% от веса щихты, а концентрат 20-24% от веса алюмини . Все это сокращает количество технологических ступеней на 50%, уменьщает продолжительность процесса в 3-4 раза, снижает трудоемкость способа на 67-75%.According to the proposed method, zirconium concentrate is used as a zirconium-containing material, which is introduced in portions into aluminum melted at 1000-1100 ° C, and the melt is thoroughly mixed, cryolite being taken in an amount of 6-8% by weight of pulping material. concentrate 20-24% by weight of aluminum. All this reduces the number of technological steps by 50%, reduces the duration of the process by 3-4 times, reduces the complexity of the method by 67-75%.
Способ осуществл ют следующим образом.The method is carried out as follows.
В тигель загружают алюминий и нагревают под слоем криолита до 1000-1100°С и при этой теМПературе ввод т небольщими порци ми циркониевый концентрат. При введении каждой порции когщентрата расплав тщательно перемещивают, очищают зеркало металла от остатков щлака и при 750-800°С разливают в предварительно нагретые до 200 250°С изложницы. Расход криолита составл ет 6-8% от веса шихты, а концентрата - 20-24% от веса алюмиии .Aluminum is loaded into the crucible and heated to 1000-1100 ° C under a layer of cryolite, and at this temperature zirconium concentrate is introduced in small portions. With the introduction of each portion of the cohcentrate, the melt is thoroughly moved, the metal mirror is cleaned of the remnant of the slag, and at 750–800 ° C is poured into molds preheated to 200–250 ° C. Cryolite consumption is 6-8% by weight of the charge, and concentrate is 20-24% by weight of aluminum.
Продолжительность предлагаемого способа 2-4 час.The duration of the proposed method is 2-4 hours.
