Description
Изобретение относитс к способам повышени механических свойств чугуна.This invention relates to methods for improving the mechanical properties of cast iron.
Известны способы производства железоуглеродистых сплавов с высокими механическими и другими свойства.ми (дл стали-легирование , термическа и химико-термическа обработка; дл чугуна-модифицирование , легирование и др.).There are known methods for producing iron-carbon alloys with high mechanical and other properties (for steel, alloying, thermal and chemical-thermal processing; for cast iron, modification, alloying, etc.).
Известен также процесс насыщени поверхности чугуна в твердом состо нии азотом при температуре 480-650, что требует длительного времени и не обеспечивает насыщени азотом всех сечений издели .It is also known to saturate the surface of a cast iron in the solid state with nitrogen at a temperature of 480-650, which requires a long time and does not provide saturation of all product sections with nitrogen.
Насто щее изобретение устран ет указанные недостатки и обеспечивает значительное повышение механических свойств чугуна за счет сплошного насыщени азотом жидкого чугуна. Жидкий чугун, имеющий температуру более 1300°, продувают аммиаком в течение нескольких минут, причем различна длительность продувки аммиака через жидкий чугун обеспечивает получение различных механических свойств последнего.The present invention overcomes these drawbacks and provides a significant increase in the mechanical properties of cast iron due to continuous saturation of liquid iron with nitrogen. Liquid iron, having a temperature of more than 1300 °, is flushed with ammonia for several minutes, and the duration of the ammonia flushing through the liquid iron is different, thus obtaining the various mechanical properties of the latter.
Предмет изобретени Subject invention
Способ повышени механических свойств чугуна, отличающийс тем, что, с целью обеспечени упрочнени чугуна, расплавленный чугун продувают аммиаком.A method of improving the mechanical properties of cast iron, characterized in that, in order to provide hardening of the cast iron, the molten iron is flushed with ammonia.
