Abstract

The invention relates to a quality improvement and control method for the surface of a copper alloy pipe. The production and manufacturing process comprises the following technological steps of (1), soaking through an aqueous solution for degreasing, (2), rinsing through clear water, (3), transferring without dust and bump damage, (4), on-line blowing of compressed air, (5), strong flushing through a lubricant of a drawing mold and (6), water blanking of the drawn pipe. According to the method, multiple control methods are adopted, the quality of the surface of the copper alloy pipe is improved effectively, it is avoided that the machining treatment effect of the surface of the alloy pipe is influenced by impurities, the use is convenient, the number of flaws of the surface of the produced copper alloy pipe is small, the use effect is good, and the service life is long.

Description

technical field [0001] The invention relates to a method for improving and controlling the surface quality of a copper alloy tube, belonging to the technical field of copper alloy tube manufacturing. Background technique [0002] The traditional production process of copper alloy tube is to use the extrusion method to extrude the semi-continuous casting or continuous casting ingot into a tube billet, and then process it into a tube by drawing or cold rolling. After the casting and rolling method was introduced, the casting and rolling method has been widely used in the production of copper pipes. Practice has shown that the production of copper pipes by the casting and rolling method has stable performance and low manufacturing costs, which can meet the stringent requirements of industries such as air conditioners and refrigerators. At present, the production technology of horizontal continuous casting tube billet, planetary rolling billet opening, double continuous drawing,...
