The invention discloses a bainite steel shot production method, and relates to the technical field of steel shot production, and the bainite steel shot production method comprises the following steps: 1, selecting leftover materials; step 2, smelting; 3, molten steel with qualified materials is injected into the centrifugal disc; and 4, drying the steel shots, selecting circles, blowing hollow parts, finely screening, detecting, packaging and warehousing. The applicant gradually masters the preparation method of the bainite steel shot through exploration and experiments for many years. By optimizing material selection and designing a reasonable preparation process, the tempering step is not needed, the Si element content of the produced steel shot is within a reasonable low range, metallographic grains are fine, good in toughness, high in impact resistance and not prone to being broken, and the service life of the steel shot product is longer. 本发明公开了一种贝氏体钢丸的生产方法，涉及钢丸生产技术领域，包括以下步骤：步骤一：选边角料；步骤二：熔炼；步骤三：将材质合格的钢水注
