Resumo
THE STEEL PRODUCTS ARE DESIGNED TO MEET SPECIFIC QUALITY REQUIREMENTS RELATED TO IMPORTANT METALLURGICAL PROPERTIES LIKE TENSILE, YIELD STRENGTH, HARDNESS, AND TOUGHNESS. THE PROPERTIES VARIABILITY CAN BE A CHALLENGING SITUATION BECAUSE THE PRODUCT CAN FAIL TO MEET THE CUSTOMERS SPECIFICATIONS. FOR THE CUSTOMER IT CAN DEMAND NEW PROCESSING EQUIPMENT SETUP, IT CAN CAUSE PRODUCTION DELAYS BECAUSE PROCESS FAILURES AND PERFORMANCE DIFFERENCES ACCORDING TO THE PRODUCTION BATCH. VARIABILITY IN THE STEELMAKING KEY VARIABLES (CHEMISTRIES, SEGREGATION, TEMPERATURES, ROLLING, COOLING), MAY RESULT IN VARIABILITY OF THE MICROSTRUCTURE, AND METALLURGICAL PROPERTIES. THE SIMULATION OF DIFFERENT PROCESS AND ALLOY DESIGN SCENARIOS CAN ALLOW BETTER UNDERSTANDING OF THE METALLURGICAL PHENOMENA RELATED TO THE PROCESS AND PROPOSE MEASURES TO MINIMIZE THE VARIABILITY, DECREASING THE SCRAPPING RISK DURING THE R&D ACTIVITIES. MICROSIM® AND PHASTRANSIM®, BOTH PREVIOUSLY USED ONLY FOR REBARS, WERE NOW USED TO SIMULATE, AND ANALYZE THE ROLLING PROCESS AND ALLOY DESIGN FOR A HYPOTHETIC SAE1045 WIRE-ROD IN AN INNOVATIVE WAY: TO PREDICT HOW THE PROPERTIES VARIABILITY BEHAVES ACCORDING TO PROCESSING AND ALLOY-DESIGN SCENARIOS. THIS KNOWLEDGE WILL ALLOW SIMULATIONS, HELPING THE TECHNICAL STAFF TO DEFINE MORE ACCURATE MODIFICATIONS IN THE ALLOY AND PROCESS DESIGN, ALLOWING REDUCED PROPERTIES VARIABILITY WHILE APPROVAL ACCORDING TO THE SPECIFICATIONS IS GUARANTEED.
