Abstract

THE DEMAND FOR IMPROVED MECHANICAL PROPERTY PERFORMANCE OF WIRE ROD PRODUCTS IS DRIVEN BY THE END USERS. THESE IMPROVEMENTS OFTEN RESULT IN HIGHER PRODUCTION COST. HOWEVER, RECENT PROCESS METALLURGY NIOBIUM HIGH CARBON SOLUTION TECHNOLOGY IS APPLIED IN WIRE PRODUCTS TO ADDRESS THIS END USER NEED AT REDUCED COST AND MEET THE VALUE ADDED DEMAND. THE PROCESS INFLUENCE IS NOW BALANCED WITH IMPROVED WIRE ROD MICROSTRUCTURE, PROPERTIES AND GRAIN SIZE CONSISTENCY. THE COMPLEMENTARY BENEFIT OF MICRO-ADDITIONS OF NIOBIUM REFINES THE MICROSTRUCTURE, REDUCES THE INTERLAMELLAR SPACING, REDUCES SCRAP, AND IMPROVES BOTH DRAWABILITY AND ROBUSTNESS. THIS WORK AIMS TO PROVIDE A COMPREHENSIVE OVERVIEW OF THE MOST POPULAR APPLICATIONS OF HIGH CARBON DRAWN WIRES, WITH THEIR CHARACTERISTICS AND ESTIMATES OF VOLUMES CONSUMED WORLDWIDE. THE MICROSTRUCTURAL EFFECT OF NIOBIUM IN HIGH CARBON STEELS IS ALSO DESCRIBED, AS WELL AS THE PIONEERING PROJECTS TO EVALUATE THE BENEFITS OF USING NIOBIUM AS A MICROALLOY IN THE WIRE BEHAVIOR DURING DRAWING AND FINAL RESULTS IN THE PRODUCT.
