Method for combining of turnout elements made of austenitic cast steel or of high-manganese steel and rails of carbon-manganese steel or carbon steel

摘要

method laczenia element (1) with austenitycznego steel or steel wysokomanganowej element (2) with steel weglowo - manganese steel or carb by przekladke posrednia (3) steel (steel) pu00f3laustenitycznej reinforced wydzieleniowo, in which the first connect method welding resistance doczolowego element of steel weglowo manganese steel or carb with przekladka,and after przycieciu at length to 25mm connect in the second zgrzewaniu przekladke element of steel or steel wysokomanganowej is characterized by thewith the przekladke shall apply staliwo pu00f3laustenityczne hardened steel or wydzieleniowo,which in the heat treatment process and operation result of phase transformation in the surface is utwardzeniu austenit - martenzyt,the first zgrzewaniu chlodzi on air and the second zgrzewaniu shall apply obru00f3bke heat polegajaca on nagrzaniu zone zgrzeiny to temperature 750u00f7770u00b0c,by the time they held out for 0.5 hour. and chlodzeniu in air.the material is used przekladki steel or staliwo about every game chemical: cmax = 0,09%, mnmax = 1.0%, simax = 1,0, pmax = 0,04%, smax = 0,03% cr = 14u00f718%, ni = 6,6u00f77,75%, mo = 2,0u00f73,0%, al = 0,75u00f71,5%beneficial steel (staliwo) about trade name 17 - 7ph (according to pn - en iso 10088: 2007 x7crniai 17 - 7) and 15 - 7mo.
