Abstract
The invention provides a device and a method for annealing a red copper straight pipe. The device is mainly composed of rollers, induction coils, racks, a power source, a control cabinet and a dust removal and purification device. The group of induction coils, the racks, the power source, the control cabinet and the dust removal and purification device are arranged on the side portion of a roller conveying line. The rollers are used for transferring pipes, the induction coils and the racks serve as main execution devices of an annealing process, the power source and the control cabinet serve as a main control device of the annealing device and provide an output power source for the annealing process, and the dust removal and purification device is used for purifying smoke dust in the operation process of the device. The annealing method comprises the four working procedures of feeding temporary storage, roller conveying, the annealing process and discharging temporary storage, the pipes firstly enter a feeding temporary storage station, then enter the rollers for conveying through a feeding mechanism and are transferred to an annealing station through the roller conveying line, the annealing process is executed, and the annealed pipes are transferred to a discharging station through the roller conveying line, and enter a discharging temporary storage frame through a discharging mechanism. The method is suitable for red copper straight pipe annealing.
Description
technical field [0001] The invention relates to hardness adjustment, plasticity optimization and internal stress elimination of straight copper pipes in the field of materials, in particular to a device and method for annealing straight copper pipes. Background technique [0002] Annealing is a metal heat treatment process, which refers to slowly heating the metal to a certain temperature, keeping it for a sufficient time, and then cooling it at an appropriate speed. The purpose is to reduce hardness, improve machinability; eliminate residual stress, stabilize size, reduce deformation and crack tendency; refine grain, adjust structure, and eliminate structure defects. [0003] Copper (that is, pure copper) has excellent electrical conductivity, thermal conductivity, plasticity and good corrosion resistance. It is widely used in the electronics industry, instrumentation and high-voltage switch industries. In industrial production, the surface hardness and The internal grain ...
