| description | The invention discloses a producing method for a D-shaped copper tube, comprising: fusion casting, heating, extrusion pressing, final finishing, acid washing, examining, head making, drafting, straightening, cropping, washing, final finishing, examining, and storing; wherein the extrusion pressing process and drafting process are: replacing extrusion pressing and drafting process in the processingof circular copper tubes in prior art with extrusion pressing and drafting of D-shaped tubes with analogical transitivity and termination product drafting. D-shaped tubes are not-exclusively symmetrical tubes with strict technical index, and the production thereof is difficult. The invented method solves the technique problem in prior art and the D-shaped tubes are not dependent on importation. |
