FIELD: metallurgy.SUBSTANCE: achievement of the required level of strength properties in the obtained high-strength wire of large diameters from rolled wire with diameter of 15-16 mm due to regulations of temperature-speed conditions of heating and intensive cooling of rolled wire during heat treatment. Besides, temperature of intensive cooling is maintained at the level of 550±10°C, and duration of exposure at rolled wire quenching is determined by the following ratio: T=740/(D*V), seconds, where D - diameter of rolled wire, mm; V- movement speed of rolled wire during intensive cooling, m/s.EFFECT: providing high strength properties of wire of large diameters, which are uniformly distributed across the cross section.1 tbl |
