Description
Предметом изобретени вл етс способ удалени дефектов (трещин , пор, неметаллических включений и т. п.) с металлических поверхностей .The subject of the invention is a method for removing defects (cracks, pores, non-metallic inclusions, etc.) from metal surfaces.
Удаление подобных дефектов с металлических поверхностей осуществл етс путем расплавлени поверхностного сло металла газовым пламенем и последующего сдувани его струей сжатого воздуха и имеет небольшую эффективность вследствие относительно невысокой температуры, развиваемой газовоГ| горелкой.The removal of such defects from metal surfaces is accomplished by melting the surface layer of the metal with a gas flame and then blowing it with a jet of compressed air and has little efficiency due to the relatively low temperature developed by the gas | burner.
При очистке металлических поверхностей, нагретых другим источником тепла, производительность этой установки возрастает.When cleaning metal surfaces heated by another heat source, the productivity of this installation increases.
Предлагаемый способ дает возможность повысить эффективность указанного известного метода очистки металлических поверхностей в том случае, когда этот метод примен етс к холодным металлическим поверхност м.The proposed method makes it possible to increase the efficiency of this known method of cleaning metal surfaces in the case when this method is applied to cold metal surfaces.
Дл этой цели предлагаетс примен ть при очистке в качестве источника тепла угольные электрические дуги. Высокотемпературное плам их вполне обеспечивает необходимую скорость прогрева металла .For this purpose, it is proposed to use carbon electric arcs for cleaning as a heat source. Their high-temperature flame completely provides the necessary rate of metal heating.
Предмет изобретени Subject invention
Способ удалени дефектов с поверхностей металлических изделий путем расплавлени поверхностных слоев и сдувани расплавленного металла сжатым воздухом, отличающийс тем, что расплавление поверхностных слоев производ т путем нагрева вольтовыми дугами, в цел х проведени очистки поверхностей как гор чих, так и холодных изделий.A method of removing defects from the surfaces of metal products by melting the surface layers and blowing off the molten metal with compressed air, characterized in that the surface layers are melted by heating with voltaic arcs in order to clean the surfaces of both hot and cold products.
