The invention provides a production method of a shoe heel steel pipe, more particularly relates to the fixed pipe which is embedded in the shoe heel and used for being knocked in by a pinned top-piece, and the invention uses a continuous rolling method for forming to replace the punch forming of a progressive die. The method is characterized in that a band material is firstly subjected to compression-sheering forming at breaking mark in accordance with predetermined length of the steel pipe, and then the band material is rolled continuously by a plurality of groups of rolling wheels with different curvatures so that the flat-shaped band material are rolled into the expected shape of a round pipe, and finally the shaped pipe material is broken off at the previous breaking mark. Therefore the heel steel pipe with required length and outside diameter is formed. Through the above method of continuous rolling, uninterrupted continuous production of steel pipes can be carried out, which enhances the production efficiency. All the steel pipes with the same diameter but different lengths can be manufactured by the same group of rolling wheel, thus being capable of reducing expenses and costs of the mold substantially.
