Description

Technical Field

[0001] The utility model relates to a high-efficiency aluminum tube tempering furnace production line, belonging to the technical field of aluminum tube heat treatment. Background Art

[0002] In conventional aluminum tube tempering furnace production lines, support chains are commonly used to transport aluminum tubes. The sprockets used to install the support chains are distributed at both ends of the tempering furnace. The return path of the support chain is always below the high temperature zone of the tempering furnace. The specific structure is shown in the attached figure. Figure 1 shown.

[0003] The conventional aluminum tube tempering furnace production line has the following technical problems during use:

[0004] 1. When the supporting chain is running, it passes through the high temperature zone, the quenching zone, the air cooling zone, and then has a long return distance. The supporting chain always enters the high temperature zone in a cold state, which increases the heating load of the high temperature zone, resulting in large heat loss and high production costs.

[0005] 2. When the supporting chain carries the aluminum tube into the quenching area, the aluminum tube is fixed relative to the chain. There is an uneven water-cooling quenching problem at the contact point between the aluminum tube and the chain, resulting in unstable product quality.

[0006] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
