Description
(54) СПОСОБ МОДИФИЦИРОВАНИЯ ЧУГУНА В ЛИТЕЙНОЙ ФОРМЕ 36 и{ую,%: IО Mg, 3 РЗМ, 6 Са, 55 Si, остальное Fe в количестве 50-80 г (0,7-1,1% от веса чугуна). Форму заливают чугуном при температуре 1450° С. Исследование структуры чугуна в эалнт1 1Х кубиках показало, что только начина с п того по ходу заливки кубика бьш шаровидньш графит. Во всех преды.цуидих кубиках - вермикул рный и пластинчатый.. Аналогичные опыты были повторены, но на поверхность лигатуры бьшо засьтано 3 г. струж кк маппш : (3,85-6,. от веса лигатуры). Нашгаа CD второго кубика в uyrjiie был шаровидный графит. Формула иэобрегени Способ модифицировани чугуна в литейной форме, включагащнй введе{П е пигатуры, содержащей магний, в реакционную камеру литниковой системы и пропускание расплавленного чугуна над лигатурой, отличающийс тем, что, с целью noDbnijreHim эффективности модифицировани , на лигатуру помещают чистый магний. Источники информзщш, принетые во внимание при экспертизе 1. Экспресс-информаци Технологи и оборудование литейного производства, 1975, № 32, с. 7-15.(54) METHOD OF MODIFICATION OF THE IRON IN THE CASTING FORM 36 and {th,%: IО Mg, 3 REM, 6 Sa, 55 Si, the rest of Fe in the amount of 50-80 g (0.7-1.1% by weight of pig iron). The mold is cast with iron at a temperature of 1450 ° C. A study of the structure of cast iron in a115X cubes showed that only starting from the fifth along the way of pouring the cube was spherical graphite. In all previous cases, the cubes are vermicular and lamellar .. Similar experiments were repeated, but the surface of the ligature was 3 years old. The origin of the lagature was: (3.85-6, from the weight of the ligature). Nashgaa CD of the second cube in uyrjiie was spherical graphite. Formula Iebrengeni Method of modifying cast iron in a mold, including the introduction of {Py e pigment containing magnesium into the reaction chamber of the gating system and passing molten iron over a ligature, characterized in that, in order to modify the efficiency of the modifying efficiency, a pure mag must be placed on the ligature for the alloy Sources of information taken into account during the examination 1. Express information Technologists and equipment of the foundry, 1975, № 32, p. 7-15.
