Remanent Tensions in Francis Type Turbine Rotors. Monoblock Alternative

摘要

In very many practical situations, in great shape pieces appear wrights after woods the metal solidification, fists. The study proposes the residual tensions determination, which reach different values in type Francis turbine rotors, monolith variant. The experimental method used is the one of electrical resistive tensometry, by drilling (perforating), in industrial factory condition.
