STUDIES OF PROFILED WIRES

UNTERSUCHUNGEN AN PROFILDRAEHTEN

IN EARLIER STUDIES PECULIARITIES CAUSED BY MANUFACTURE WERE ESTABLISHED IN Z-PROFILED WIRES USED IN THE PRODUCTION OF CLOSED BRIDGE CABLES; THESE PECULIARITIES ARE NOT A DISADVANTAGE UNDER PURE TENSILE THRESHHOLD STRESS, BUT MAY INFLUENCE THE DURABILITY OF THE WIRES WHEN THEY ARE SUBJECTED TO BENDING AND TORSIONAL STRESSES. IT WAS THEREFORE REGARDED AS IMPORTANT TO FOLLOW THESE FINDINGS BY TECHNOLOGICAL EXAMINATIONS WITH A VIEW TO CONCLUDING THAT THE DIFFERENT FINISH OF PROFILED WIRES IS DIRECTLY RELATED TO THE TECHNOLOGICAL VALUES. A PLAN OF WORK WAS PREPARED WHICH ANTICIPATED THE CARRYING OUT OF TESTS ON SINGLE WIRES AS WELL AS CHEMICAL ANALYSES AND METALLOGRAPHIC TESTS. AT LEAST 25 WIRE RINGS WERE TESTED AT EACH OF THREE FACTORIES.
