(54) СПОСОБ ПОЛУЧЕНИЯ ДРОБИ ИЗ ЖЕЛЕЗОУГЛЕРОДИСТЫХ(54) METHOD FOR OBTAINING CRUSHERS FROM IRON-CARBON
СПЛАВОВALLOY
Изобретение относитс к литейному производству, в частности к получению металлической дроби из стали или чугуна. ч Дробь, легированна алюминием, об ладает повышенной износостойкостью, а также обуславливает реализацию ме (Тода позднего раскислени металла алюминием при ее вводе в расплав. По лучаема дробь используетс при суспензионной разливке, наплавке в сварочном производстве и дробеметной очистке. Известен способ получени дроби, включающий распьшение струи жидкого металла газом, при котором в струю газа ввод т тонкодисперсный металлический порошок, представл инций распы л емый металл tOОднако известный способ невозможно-использовать дл получени легиро ванной дроби, так как введение в струю газа металлического порошка того же химического состава, что и . распыл емый металл, позвол ет, лишь воздействовать на механизм дроблени струи жидкого металла и формирование капли, но не вли ет на изменение химического состава получаемой дроби, так как химические составы расплава и вводимого порошка одинаковы. Кроме того, введение порошка алюмини также неэффективно, так как при попадании в факел распылени струи металла частшцл алюмини нагреваютс , плав тс и взаимодействуют с кислородом, образу в зкие плены, состо пще в основном из окиси алюмини с температурой плавлени . При этом резко измен етс межфазна знерги на границе капл -атмосфера, првьшгаетс зкость капли расплава, и уменьшаетс врем сфероидизации частицы, что приводит к ухудшению характера формы, образованию .частиц неправильной конфигурации с развитой поверхнос.тью и нестабильным составом по алюминию.The invention relates to foundry, in particular to the production of metal shot from steel or cast iron. The fraction doped with aluminum has a high wear resistance and also causes the realization of me (Toda late metal deoxidation with aluminum when it is introduced into the melt. The resulting shot is used for suspension casting, welding welding and shot blasting. A method is known for producing shot, including disintegration of a jet of liquid metal by gas, in which a finely divided metal powder is introduced into the stream of gas, represents the sprayed metal, tOHowever, a known method cannot be used for producing doped shot, as the introduction of a metal powder of the same chemical composition into the gas jet as the metal being sprayed only allows the crushing mechanism of the liquid metal jet and the formation of a drop to affect the crushing mechanism, but does not affect the change in the chemical composition of the resulting fraction since the chemical compositions of the melt and the injected powder are the same. In addition, the introduction of aluminum powder is also inefficient, since when a metal jet enters the spray, the metal particles of aluminum heat up, melt and interact with oxygen, forming viscous films, consisting mainly of alumina with a melting point. At the same time, the interfacial energy at the boundary of the drop-atmosphere changes dramatically, the viscosity of the melt drop is reduced, and the time of spheroidization of the particle decreases, which leads to a deterioration of the shape of the shape, the formation of particles of irregular configuration with developed surface and unstable composition on aluminum.
