Method for producing copper alloy coil pipe

Abstract

The invention relates to a method for producing a metal pipe, in particular to a method for producing a copper alloy coil pipe. According to the technical scheme provided by the invention, the method for producing the copper alloy coil pipe comprises the following steps: (a) melting, (b) horizontal and continuous casting, (c) face milling, (d) primary bright annealing, (e) planetary tube rolling, (f) stretching, (g) secondary bright annealing, (h) cleaning, and (i) third bright annealing. The method can improve the comprehensive finished product rate of a pipe material, the labor productivity and the grade of product quality.

Description

technical field [0001] The invention relates to a production method of a metal pipe, in particular to a production method of a copper alloy coil pipe. Background technique [0002] At present, domestic copper alloy coils have not yet been fully developed, produced and applied, and the original straight tube production process is still used. The production process of traditional straight pipes is as follows in sequence: Cu+Ni+Fe, melting, spectral analysis, semi-continuous casting, sawing, inspection, electric heating, extruding pipe, cutting head and tail pipe, manually repairing and scraping the surface, Inspection, cold-rolled pipe, cutting to length, inspection, bright annealing, head making, drawing, peeling, multi-pass drawing, inspection, length segmentation, head making, multi-pass drawing, cutting to length, inspection , deburring and chamfering at both ends, straightening, flaw detection, cleaning copper scraps and oil stains on the inner wall, cleaning the oil sta...
