Arrangement structure of cross-span transverse moving type RH vacuum refining device of vacuum tank car

The invention relates to an arrangement structure of a cross-span transverse moving type RH vacuum refining device of a vacuum tank car, the RH vacuum refining device comprises a vacuum tank, a processing station of the vacuum tank is arranged on a converter span, and a hoisting station and a maintenance station of the vacuum tank are arranged on a molten steel receiving span. The vacuum tank can transversely move between the converter bay and the molten steel receiving bay along with the vacuum tank car; the vacuum tank is detachably connected with a hot bent pipe, and the hot bent pipe can transversely move between a converter bay and a molten steel receiving bay along with the vacuum tank; and the hoisting station of the hot bent pipe and the maintenance station of the hot bent pipe are arranged on the molten steel receiving bay. The defects that when an RH vacuum refining device is arranged in an old workshop, the converter span does not have a large-tonnage crane and does not have enough space for arrang
