Description
Известно применение термитной смеси при приварке стыковых рельсовых соединителей на железных дорогах СССР по авт. св. № 77895. Как показа.та практика при применении этой смеси, прочность наплавки оказываетс невысокой, кроме того пр;-; производстве термитной смеси нельз использовать полуавтоматические дозаторы с объемным отмеривапиегл.It is known the use of thermite mixture when welding butt rail connectors on the railways of the USSR on author. St. No. 77895. As practice shows when using this mixture, the hardness of the deposit is low, except that; -; In the production of thermite mixtures it is not possible to use semi-automatic dispensers with volumetric measuring.
В предлагаемом изобретении с целью повышени прочности наплавки термитного металла, в смесь ввод т 80%-ный ферромарганец в количестве 20-25% от вход щей в состав термита окиси меди. При этом можно получить наплавку термитного металла, состо щую в основном из меди и марганца.In the present invention, in order to increase the strength of the welding of a thermite metal, 80% ferromanganese is introduced into the mixture in an amount of 20-25% of the copper oxide included in the termite composition. At the same time, it is possible to obtain surfacing of thermite metal, consisting mainly of copper and manganese.
Такил образом, приварка соединителей осуществл етс марганцевистой бронзой, обладающей больщей твердостью и прочностью по сравнению с медью.In this way, the welding of the connectors is carried out with manganese bronze, which has greater hardness and strength compared to copper.
Предмет изобретени Subject invention
Термитна смесь по авт. св. Ль 77895, отличающа с тем, что, в цел х увеличени прочности наплавки термитного металла и расщирени допусков состава термита , состо щего из химического соединени меди и алюмини в количестве 20% и окиси меди в количестве 64%, в состав термита ввод т дополнительно (80-85%) малоуглеродистый ферромарганец в количестве 20-25% от окиси меди.Termite mixture auth. St. It is 77895, characterized in that, in order to increase the strength of the welding of thermite metal and to expand the tolerances of the composition of the termite, consisting of a chemical compound of copper and aluminum in an amount of 20% and copper oxide in an amount of 64%, 80-85%) low-carbon ferromanganese in the amount of 20-25% of copper oxide.
