Title:
ショットピーニング用投射材の製造方法
Document Type and Number:
Japanese Patent JP5381045
Kind Code:
B2
Abstract:
Provided is a method for manufacturing a blasting material for shot peening with which a reliably high level of hardness can be achieved while preventing an increase in the material cost. Quenchable steel is used as a material in a blasting material manufacturing step (S10). After granules (4) which are quenched by means of a water atomization method are formed in a quenching step (S20), the granules (4) are tempered inside a heating furnace (5) at a prescribed temperature (from 130-230 °C ,and preferably from 160-230°C) For a prescribed amount of time in a tempering step (S30). A work hardening treatment is applied in a work hardening step (S40) wherein the granules (4) are blasted/bombarded onto a target material (7) to apply stress to the granules (4) using an apparatus for shot peening (6).
