Description

. Иарбретвние относ тс  к чернЫ метаплургвн , а вменно к технике попучени  ста в и сплавов в сталеплавильных аррегатах .. Iarbretvnie refers to the chernYa metaplurgvn, and in turn to the technique of popucheni hundred in and alloys in steelmaking facilities.

Известны способы выплавки 1шэко- j /глеропистых нержавеющих хромоникельмаргаиоевык сгалей, эахлючаюшеес  в том, что провесе обеe/rj pоживани  прск всмв1 с  тфрдувкой металлического расплава кислородом.fQKnown methods of smelting 1s-j / hleropisty corrosion-proof chromium-nickel margai sacks, which is caused by the fact that both / rj living conditions of the molten metal with oxygen are melted.fQ

Недостатками способов получевв  нержавеющих сталей  вл ютс  повышенные угары хрома в марганца и перегрев металла за. счет локального переокиспенв  расплава в зове реакоив во врем  )5 «к слвтельиого рафинировани  кисл1ч оиом,The disadvantages of the stainless steel method are the increased chromium fumes in manganese and the overheating of the metal in. by local melt peroxidation in the call of the reactants during) 5 "to slurry refining with acid,

Известен также способ получени  хромое адержа иих нержавеющих сталей в дуговой электропечи, в котором .после достижени  в прсщессе проаувки содержа 20 ВИЯ углерода 0,1-0,25% в металл присаживают кремний из расчета введеии  го в количестве 0,S-1,S% и продолжают прхшувку до требуемого содержани , углерода;25There is also known a method of obtaining lame steel holders and their stainless steels in an electric arc furnace, in which after reaching a proouwka containing 20 WIE carbon 0.1-0.25% in the metal, silicon is applied to the metal at the rate of 0, S-1, S % and continue to reach the desired carbon content; 25

Однако введение кремни  в расплав при выплавке высоксмарганпевс нер жавеющей стали не предохран ет мйрганец от оквслени  в процессе рафинировани  от углерода, что приводит к значительным , перерасходам металлического марганца в период доводки металла по химическому составу.However, the introduction of silicon into the melt during the smelting of high marganpevs stainless steel does not prevent the Mirganian from being oxidized to carbon from the refining process, which leads to significant overruns of manganese metal in the period of fine-tuning the metal by chemical composition.

Целью изобретеви   вл етс  повышени степени исшользрванин хрома и марганца : шихты и сокращение расхода беауглеродиотых сортов феррохрома и металлического марганца.The aim of the invention is to increase the degree of chromium and manganese use: the charge and the reduction of the consumption of carbon-free grades of ferrochrome and metallic manganese.

Это достигаетс  тем, что силикс арп ганец ввод т перед началом рафинировани  расплава от углерода при концентрации последнего в металла 0,215-0,12% в количестве, обеспечивающем содержани . кремни  Н марганца на 0,5-5% выше требуемого по химическому составу| присаживают на шлак в мелкопробленОм виде 8-10% вводимого силикомарганца.This is achieved by introducing silicic arganite before the start of the melt refining from carbon at a concentration of 0.215-0.12% in the metal in the amount providing the content. silicon H manganese 0.5-5% higher than the required chemical composition | 8-8% of injected silico-manganese are placed on the slag in small-grained form.

Дальнейшее обезуглероживание расплава провод т газокислородной смесьюFurther decarburization of the melt is carried out by the gas-oxygen mixture.
