Description

[0001] technical field [0002] This application relates to the manufacture of heating furnace tubes, specifically a straight-line heating furnace tube bending process. [0003] Background technique [0004] Heating furnaces are widely used in industry, such as billet heating, workpiece heat treatment, etc. In order to increase the heating uniformity of the heating furnace, the furnace tube is often bent. [0005] In the prior art, in order to ensure the requirements for the specific shape of the heating furnace and meet the respective requirements for the specific heating heat, it is usually necessary to bend the shape of the furnace tube in a specific shape. For the bending of the furnace tube of the heating furnace, stamping is often used in the prior art. This forming method can efficiently and quickly realize bending processing, has high processing precision and low cost, and is widely used in the prior art. However, this heating method is easy to produce a large...
