Description

Изобретение относитс к металлургии, & частности, к выплавке легирова1гаых ста ей и сплавов в электрических печахаThis invention relates to metallurgy, & in particular, to the smelting of alloyed steel and alloys in electric furnaces
Известен способ выплавки вольфрамсодер- жащих сталей, когда легирование врпьфрамом производ т путем присадки ферровольфрама в завалку 1 .There is a known method of smelting tungsten-containing steels, when alloying with waxfram is made by adding ferro-tungsten to filling 1.
Известен также способ выплавки вопьфрамсодержащих сталей и сплавов, согласно которому легирование вольфрамом производ т путем присадки вольфрамсодержашей лигатуры в жвдкий металл совместно с кремнием и алюминием, а последующую продувку металла кислородом ведут до полного расгшавдени шихты и снижени содержани углеро- да в расплаве на О,,4О% 2 .There is also known a method of smelting steel-containing steels and alloys, according to which alloying with tungsten is made by adding tungsten-containing ligature to the liquid metal together with silicon and aluminum, and subsequent purging of the metal with oxygen leads to complete dissolution of the charge and reduction of carbon content in the melt in O. 4O% 2.
. Недостатком этого способа вл етс значительные потери вследствие насьи ени футеровки подины. Это св зано с тем, что из-за высокой тугоплавкости вольфрама в области подины значительное врем наблюдаетс повышенна концентраци вольфрама по сравнению с его средним: содержанием в объеме металлической ванны . The disadvantage of this method is a significant loss due to saturation of the bottom liner. This is due to the fact that due to the high refractoriness of tungsten in the bottom region, an increased concentration of tungsten is observed for a considerable time compared to its average content in the volume of the metal bath.

При традиционных способах легкфованш металла во ьфрамсодержашей лигатурой в видекусков от-ери вачьфрама за счет на сьпцен1Ш вольфрамом одины могут дос 11гат 80% от общих потерь вольфрама З. .With traditional methods, lightweight metal in a ligature-containing ligature in video pieces from a wachfram at the expense of tungsten tungsten can reach up to 80% of the total loss of tungsten Z.
Целью изобретени вл етс увел иеннв равномерности распреде ени вольфрама и объеме сндкой eairau и повышение степени его усвоени мегаппом. ,The aim of the invention is to increase the uniformity of the distribution of tungsten and the volume of the eairau and increase its degree of absorption by the megapp. ,
Это достигаетс тем, что Б ii3Beci4iOM способе выилавга таких сталей и сплавов, включающем рас 1лавленр е металл гческой ШИХТЫ, БведеЯнр вольфрамсодер-жащей лиге- ратуры совместное активнымвосстайовйте лем, nocneajToHiyio кислбродную продувку п рафинирование мбтатша, Вог1ь41рамсодержа щую пигзгуру ввод т на шпак & зйце аисперсной смесй с комплексным восстанови тепем, в котором одни на компонекго при взаимодействи с окислами шпака к Кислородом , 1застворенным в металле, образуйт газообразный продукт реаклии.This is ensured by the use of technology and technology. A zyze dispersed mixture with a complex reduction, in which, alone on a component when interacting with oxides of the shpak to Oxygen, 1 dissolved in the metal, forms a gaseous reaction product.
