Изобретение относитс  к производству прецизионных сплавов.The invention relates to the production of precision alloys.

Известен способ выплавки железо-алюминиевых сплавов сплавлением чистых шихтовых материалов с введением алюмини  под криолитовый шлак. Однако, такой способ не обеспечивает равномерного распределени  алюмини  в микрообъеме сплава, что пр-иводит к ухудшению пластичности металла и к по влению микротрещин в процессе деформации , а также снижает магнитные свойства сплава.There is a method of smelting iron-aluminum alloys by fusing pure charge materials with the introduction of aluminum under cryolite slag. However, this method does not ensure uniform distribution of aluminum in the microvolume of the alloy, which leads to a deterioration of the plasticity of the metal and the appearance of microcracks in the deformation process, and also reduces the magnetic properties of the alloy.

Предлагаемое изобретение основано на том, что при выплавке этих сплавов в них ввод т свинец (или другие элементы 4-ой группы подгруппы свинца) в количестве от 0,001 до 0,5%.The present invention is based on the fact that during the smelting of these alloys lead is introduced into them (or other elements of the 4th group of the lead subgroup) in an amount of from 0.001 to 0.5%.

Свинец (или другой поверхностно-активный элемент) способствует выравниванию содерл ани  алюмини  по зерну, что позвол ет избежать по влени  микротрещин на границах зерен. В результате этого улучшаетс  пластичность сплавов. При гор чей и теплой деформации не наблюдаетс  образование трещнн и по вл етс  возможность холодной прокатки этих сплавов. Кроме того, значительно улучшаютс  магнитные свойства и их стабильность.Lead (or other surface-active element) helps level the aluminum content of the grain, thus avoiding the appearance of microcracks at the grain boundaries. As a result, the ductility of the alloys is improved. During hot and warm deformation, the formation of cracks is not observed and the possibility of cold rolling of these alloys appears. In addition, the magnetic properties and their stability are greatly improved.

Свинец (или другой поверхностно-активный элемент) можно вводить в плав в концеLead (or other surface-active element) can be introduced into the water at the end

плавки перед сливом металла в тигель, в ковщ или в изложницу.melting before pouring metal into a crucible, into a ladle or into a mold.

В открытой индукционной печи емкостью 10 кг была выплавлена сери  плавок наиболее труднодеформируемого сплава 16Ю, содержащего 16% алюмини . В магнезитовом тигле расплавл ли железо под основным известковым шлаком. По расплавлении проводили раскисление боркальком. Затем известковый ш.лак снимали и наводили криолитовый . Под криолитовый шлак присаживали алюминий. После введени  всего алюмини  метллл доводили до температуры слива, котора  определ лась началом кипени  криолита, и вводили свинец (0,001- 0,05). Затем проводили разливку в круглые изложницы. Полученные слитки ковали и катали на ленту. На кованых сутунках и лентах трещин и рванин не было.In an open induction furnace with a capacity of 10 kg, a series of melts of the most difficult-to-deform 16U alloy containing 16% aluminum was melted. In a magnesite crucible, iron was melted beneath the main calcareous slag. After melting, borkalkom was deoxidized. Then limestone sh. Lak was removed and induced cryolite. Aluminum was seated under cryolite slag. After the introduction of total aluminum, the metal was brought to a drain temperature, which was determined by the start of cryolite boiling, and lead was introduced (0.001-0.05). Then, casting into round molds was performed. The resulting ingots were forged and rolled onto a tape. There were no cracks and flaws on the forged suns and ribbons.
