Known ligature on the basis of nickel, containing copper and magnesium, is used to obtain iron with a spherical shape of graphite | T. The disadvantage of this ligature is the presence of gas porosity in it, which reduces the density of the ligature, which worsens the process of alloying pig iron due to the rise of ligature and an increase in the loss of magnesium. The closest to the invention in terms of textiles and the effect achieved is ligature 2 for cast iron of the following composition / wt.%: Nickel Magnesium Rare-earth 0-1 metals 0.06 Remaining Iron The disadvantage of this ligature is low density due to the presence of gas porosity of 66.4 g / cm; low absorption of magnesium by iron; a residual magnesium content of 0.016-0.04%; and low strength of doped iron. ... tensile strength of cast iron containing, weight%: carbon 3.5-3.7; silicon 1.8-2.2; manganese 0.3-0.5; chromium 0.06-0.08; phosphorus 0.03-0.07} sulfur 0.003-0.008, the leg of the known ligature composition is 64.788 kg / mm. The purpose of the invention is to increase the density of the pigment, to increase the absorption of magnesium and to increase the strength of the iron. To achieve ueira P1 attachment ligature For cast iron, nickel, magnesium, rare earth metals, iron and copper, additionally harden silicon and zinc with the following ratio of compressed substances, wt.%: 0.5-50 Nickel 3-20 Magnesium Rare-earth 0.05 -1.5 metals 0.1-4.0 Iron 0.1-10.0 Silicon 0.5-10.0 Else Example. The ligature is melted in an induction furnace. Iihtu is prepared
из гранулированного никел , катодной меди, ферросилици и . Лиratypiy йыплавл ют под слоем флюса, навддимого хлористым натрием.from granulated nickel, cathode copper, and ferrosilicon. Liratypiy is melted under a layer of flux, preferably sodium chloride.
Лигатуру а количестве 0,3-0,9% отвесамё е1лла ввод т в чугун слейующего состава, вес.%: углерод 3,53 ,7, кремний 1,8-2,2, марганец 0,30 ,5, хром 0,06-0,08, фосфор 0,030 ,07, сера 0,003-0,008.The ligature a quantity of 0.3-0.9% of the weight loss of el1 is introduced into the cast iron of the following composition, wt.%: Carbon 3.53, 7, silicon 1.8-2.2, manganese 0.30, 5, chromium 0, 06-0.08, phosphorus 0.030, 07, sulfur 0.003-0.008.
Легирование осуществл ют при 1450-1500°С.The doping is carried out at 1450-1500 ° C.
В таблице приведены составы предложенной лигатуры, ее свойства и Ьвойства легированного чугуна.The table shows the compositions of the proposed ligature, its properties and properties of doped iron.
Из приведенных в таблице данных следует, Чгб предложенна лигатура в сравнении с известной имеет более высокую плотность и обеспечивает Повышение усвоени магни чугуном ч его прочность.It follows from the data in the table that the proposed ligature, in comparison with the known, has a higher density and provides for an increase in the absorption of magnesium by the cast iron and its strength.
