Abstract

The invention relates to a continuously cast bolt made of an aluminum-based alloy for an extruded profile that has a yield strength of greater than 260 MPa, preferably greater than 280 MPa, in particular greater than 300 MPa. According to the invention, it is provided that the aluminum-based alloy contains, in percentage by weight, greater than 0.0% to 0.40% iron, 0.40% to 1.2% magnesium, 0.60% to 1.1% silicon, greater than 0.0% to 0.35% copper, greater than 0.0% to 0.35% chromium, 0.40% to 0.95% manganese, up to 0.2% zinc, optionally 0.005% to 0.15% titanium and/or 0.005% to 0.15% titanium diboride, and a remainder of aluminum and production-related impurities, wherein a secondary dendrite arm spacing of the microstructure is less than 100 μm. The invention furthermore relates to an extruded profile created from a continuously cast bolt of this type, and to a method for producing an extruded profile.

Abstract

The invention relates to a power rail (10) for movable power consumers, in particular for electrically driven vehicles, preferably rail vehicles, having a carrier profile which comprises a first carrier profile element (12) and a second carrier profile element (14) which are coupled to one another along a surface (13a, 13b) which is partially curved, and a head profile (16) which has a first lateral section (16a) and a second lateral section (16b) lying opposite, and which is connected in a positively engaging and/or frictionally engaging fashion to the first carrier profile element (12) and to the second carrier profile element (14), wherein an end of the surface (13a, 13b) which faces the head profile (16) is arranged closer to the second lateral section (16b) than to the first lateral section (16a). The power rail according to the invention is characterized in that the two carrier profile elements (12, 14) are coupled to one another in a positively locking fashion and/or frictionally locking fashion along the surface (13a, 13b) by means of the head profile part (16). Furthermore, the invention relates to a corresponding method for mounting or dismounting a power rail (10) and to a system composed of multiple axially combined power rails.
