Abstract
Способ получения нержавеющей аустенитной стали, включающий выплавку полупродукта в одной печи и лигатурного сплава в другой с последующим их перемешиванием и рафинированием в сталеразливочном ковше, отличающийся тем, что в качестве полупродукта выплавляют сплав на основе железа и элементов, входящих в состав стали и понижающих растворимость азота в железе, а лигатурный сплав выплавляют с составом элементов, входящих в состав стали и повышающих растворимость азота в железе и вводят в лигатурный сплав азот до содержания, которое рассчитывают по формуле: ! , где ! Q - содержание азота в лигатурном сплаве, мас.%; ! Мл - масса лигатурного сплава, т; ! Мп - масса полупродукта, т; ! [N]p - стандартная растворимость азота в выплавляемой стали, мас.%.A method of producing stainless austenitic steel, comprising the smelting of an intermediate in one furnace and a ligature alloy in another, followed by their mixing and refining in a steel pouring ladle, characterized in that an alloy based on iron and elements that make up the steel and reduce the solubility of nitrogen is smelted as an intermediate in iron, and the ligature alloy is smelted with the composition of the elements that make up the steel and increase the solubility of nitrogen in iron and nitrogen is introduced into the ligature alloy to a content that is calculated are specified with the formula: where! Q is the nitrogen content in the ligature alloy, wt.%; ! ML - the mass of the ligature alloy, t; ! MP - the mass of the intermediate product, t; ! [N] p is the standard solubility of nitrogen in the melted steel, wt.%.
