【Abstract】 To study influence of heating time on mechanical properties of steel wire during heat treatment systematically, and strength curve of steel wire with various diameters is obtained during heating. The mathematical relationship between time of complete austenitizing of steel wire and diameter of steel wire is fitted. The effect of lead bath quenching temperature on spacing and mechanical properties of steel wire microstructure layers was studied, microstructure and performance characteristics of steel wire under different lead bath quenching temperatures were compared, the optimal quenching temperature of steel wire with different diameters was determined. Provide reference for setting of heat treatment process parameters in steel wire production.更多还原
