摘要 |
FIELD: technological processes. ^ SUBSTANCE: bar is heated up to the temperature that provides homogenisation of steel high-temperature phase. Then spring is wound from bar at its heating temperature. At that spring is subjected to turn-by-turn tempering. Tempering of every turn is carried out after its winding and after-winding ageing in time sufficient for steel polygonisation for complication of recrystallisation rearranging of its structure. Final thermal treatment of spring is carried out by means of its tempering. ^ EFFECT: higher strength and operational durability of produced spring. |
