1. Способ производства высокопрочной мартенситностареющей стали, включающий загрузку в вакуумную индукционную печь шихты, содержащую железо, никель, молибден, кобальт без отходов, ее расплавление и раскисление редкоземельными металлами (РЗМ), введение титана, форсированную плавку с последующим введением магния и кальция, выпуск расплава, получение слитка и его дальнейший переплав в вакуумной дуговой печи, отличающийся тем, что в вакуумную индукционную печь после расплавления шихты вводят окись никеля из расчета 0,45-0,55% от веса расплава с выдержкой 15-30 минут при Т=1600-1650°C, после чего в качестве РЗМ последовательно в порядке повышения степени их раскислительной способности вводят иттрий, диспрозий, неодим, церий и лантан в количестве 0,01-0,05% каждого элемента.1. A method for the production of high-strength maraging steel, comprising loading a mixture containing iron, nickel, molybdenum, cobalt without waste into a vacuum induction furnace, its melting and deoxidation with rare earth metals (REM), the introduction of titanium, forced melting, followed by the introduction of magnesium and calcium, production melt preparation of the ingot and its further remelting in a vacuum arc furnace, characterized in that nickel oxide is introduced into the vacuum induction furnace after the charge is melted at the rate of 0.45-0.55% by weight of melt with an exposure of 15-30 minutes at T = 1600-1650 ° C, after which yttrium, dysprosium, neodymium, cerium and lanthanum are introduced in an amount of 0.01-0.05% each in order to increase the degree of their deoxidation item. 2. Способ по п. 1, отличающийся тем, что введение в расплав первой половины от всей массы РЗМ осуществляют предварительно за 10-15 минут перед вводом второй половины РЗМ.2. The method according to p. 1, characterized in that the introduction into the melt of the first half of the total mass of rare-earth metals is carried out previously 10-15 minutes before entering the second half of the rare-earth metals. 3. Способ по п. 1, отличающийся тем, что введение магния и кальция в суммарном количестве 0,02-0,06% к массе шихты проводят перед выпуском расплава при давлении 100-200 миллиметров ртутного столба.3. The method according to p. 1, characterized in that the introduction of magnesium and calcium in a total amount of 0.02-0.06% by weight of the charge is carried out before releasing the melt at a pressure of 100-200 millimeters of mercury.
