Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing.

[0024] An aluminum and aluminum alloy parallel flow tube continuous extrusion coil process, comprising the following steps:

[0025] (1) Cleaning. Clean the aluminum rods in a bar cleaning machine to remove oil and dust on the surface of the aluminum rods, and remove the burrs on the end faces of the rods.

[0026] First clean the aluminum rod 1 in the rod cleaning machine 2. The cleaning machine 2 not only removes the oil and dust on the surface of the aluminum rod 1, but also has the function of removing the burr on the end surface of the rod to prevent foreign objects from damaging the extrusion during the extrusion process. Mold 5 and cause poor product inclusions.

[0027] (2) Preheating, the cleaned aluminum rods will be preheated to 420-480°C in a suspended intermediate frequency induction heating furnace.

[0028] The cleaned aluminum rod 1 will be preheated to 42...

Abstract

The invention discloses a technology for continuously extruding coils by aluminum and aluminum alloy parallel flow pipes, which comprises the following steps of: (1) cleaning, (2) preheating, (3) extruding, (4) zinc spraying, (5) cooling, (6) drying, (7) flaw detection ink jetting, and (8) rolling. The technology integrates continuous extrusion, zinc spraying, cooling, drying, flaw detection, flaw marking, rolling and other processes, has high automation degree, stable process and quality, and high production efficiency, and the continuous batch production is successfully realized; the disqualified part of the product is more thoroughly marked; the drying of the product adopts a double-level drying process of a cold knife and hot blast tunnel drying equipment; and the production process is environmental-friendly and safe.

Description

technical field [0001] The invention relates to an aluminum and aluminum alloy parallel flow pipe continuous extrusion coil process, which belongs to the technical field of aluminum and aluminum alloy extrusion processing. Background technique [0002] Aluminum and aluminum alloy parallel flow tubes have many advantages such as light weight, good thermal conductivity, good corrosion resistance, good processability, and recyclability. They have been widely used in automobiles and household air conditioners, and have broad market prospects. With wide application, the quality requirements for parallel flow tubes are becoming more and more stringent, especially for the control of inclusions, pinholes, cracks, scratches and other defects that may cause leakage. [0003] The original commonly used process steps are: preheating→extrusion→spraying zinc→cooling→drying→winding. The disadvantages of this process step are: ①The oil and dust on the surface of the aluminum rod are easily...
