METHOD FOR FIXING BLADE TO OUTER PERIPHERY OF ROTOR MAIN BODY OF STEAM TURBINE |
摘要 |
Steam turbine blades are fastened in an outer layer of weld material applied by deposit welding to the outer surface of the rotor body, the composition of the weld material being optimally matched with respect to hot strength and/or corrosion resistance, in particular stress corrosion resistance, to the local mechanical, thermal and chemical requirements. A possible option is additionally to insert a deposit welded intermediate layer of medium alloying element content. Steels with 10-14% Cr, low carbon and additions of Mo and possibly V are preferred as the weld material for the layer. |
