Claims (4)

1. Способ формирования защитной оболочки на раскислителе стали, состоящей из стали, отличающийся тем, что защитный слой формируется путем внедрения в поверхность раскислителя предварительно нагретой до температуры начала его плавления стальной дроби (отходов дроби) размерами 0,2÷1,5 мм под давлением 2÷3 кг/см2, а увеличение толщины оболочки достигают дополнительной обмазкой пастой, состоящей из металлической пыли (отходов дроби) и углеводородного связующего.1. The method of forming a protective shell on a deoxidizer of steel, consisting of steel, characterized in that the protective layer is formed by introducing into the surface of the deoxidizer pre-heated to the temperature of the beginning of its melting steel shot (shot fractions) with dimensions of 0.2 ÷ 1.5 mm under pressure 2 ÷ 3 kg / cm 2 , and an increase in the shell thickness is achieved by additional coating with a paste consisting of metal dust (waste fractions) and a hydrocarbon binder. 2. Способ по п.1, отличающийся тем, что внедрение частиц дроби происходит в процессе выдержки раскислителя при температуре начала его плавления в слое стальной дроби (отходов дроби) толщиной 50÷70 мм в течение 4 ч под давлением 2÷3 кг/см2, а увеличение толщины оболочки достигают дополнительной обмазкой пастой, состоящей из металлической пыли (отходов дроби) и углеводородного связующего.2. The method according to claim 1, characterized in that the introduction of the particles of the fraction occurs during the exposure of the deoxidizer at the temperature of the beginning of its melting in the layer of steel shot (shot wastes) with a thickness of 50 ÷ 70 mm for 4 hours under a pressure of 2 ÷ 3 kg / cm 2 , and an increase in the shell thickness is achieved by additional coating with a paste consisting of metal dust (waste fractions) and a hydrocarbon binder. 3. Способ по п.2, отличающийся тем, что внедрение частиц стальной дроби в поверхность более мягкого раскислителя производят методом ударного воздействия, а увеличение толщины оболочки достигают дополнительной обмазкой пастой, состоящей из металлической пыли и углеводородного связующего.3. The method according to claim 2, characterized in that the introduction of particles of steel shot into the surface of a softer deoxidizer is carried out by the impact method, and an increase in shell thickness is achieved by additional coating with a paste consisting of metal dust and a hydrocarbon binder. 4. Способ по п.3, отличающийся тем, что в качестве раскислителя используется алюминий при его массовом соотношении с материалом защитного слоя 1:(0,2÷0,8).4. The method according to claim 3, characterized in that aluminum is used as a deoxidizer in its mass ratio to the protective layer material 1: (0.2 ÷ 0.8).
