2, aluminum tube induction heating continuous annealing production line system equipment operation plan:

2. 1 aluminum tube induction heating continuous annealing production line system power selection:

Heating power in accordance with your request selected 400m / min, the choice of 400KW.

2. 2 choice of aluminum tube induction heating continuous annealing production line program:

The heating method can make the aluminum tube have a short-term heat preservation process in the part without the furnace body, and the heat preservation process ensures the grain structure refinement process in the annealing process of the aluminum tube , so that the internal grain is fine, Equilibrium, so that the aluminum tube can be annealed to meet your company's processing requirements. At the same time, the heated aluminum tube in the heating furnace does not cause an excessive temperature difference in the axial direction, so that the micro crack caused by the thermal stress can be overcome in some procedures.

2.3 heating device configuration and process implementation:

The required power supply 400KW / 6KHZ is used to supply power to the two heating furnaces. The two heating furnaces heat the aluminum tubes . After each furnace body is quickly heated by the aluminum tubes , after a short period of heat preservation, the process is no heating process, in order to prevent aluminumpipe into the next station down when the induction furnace can not be aligned, a mechanical roller means is positioned intermediate; aluminum to prevent oxidation of the heating process, the two-bit portion of the furnace and charged with a guide In the sealed outer casing, inert gas is introduced into it; the length of each furnace body is 400MM, the distance between the mechanical roller device and the furnace body is 20mm on one side, and the total length of the furnace body is 800MM. Considering the space occupied by the outer casing The total length of the heating portion needs to be 1200 MM.

The two furnace bodies and a set of mechanical roller device bases are fixed on the same furnace body base. The outer shell of the furnace body is made of hard aluminum alloy, which can simultaneously protect the gas sealing and magnetic shielding, so that the frame, the roller, etc. It is not heated by magnetic flux leakage; the shell of the furnace body is designed to be detachable, which provides convenience for the inspection of the furnace body and the replacement of the mechanical roller device.
