Background

The molten salt furnace is a very important device in a melamine device and has the function of heating molten salt sent from a molten salt tank to raise the temperature of the molten salt to about 450 ℃, and then sending the heated molten salt to a triamine reactor and other devices for circulating heat exchange. The radiation section is the most important part, and the coil pipe parts have high requirements due to large diameter, wall thickness, more coil pipes in groups (generally 6 or more coil pipes in the radiation section are aligned in parallel), and high requirements, so that the radiation section is made with key points and difficulties. The single-group coil pipe is a spiral pipe formed by welding a plurality of bent pipe sections. The traditional method of single-unit coil assembly is to make a cylinder, spot-weld each bent pipe section on the cylinder, and then weld each pipe section. Because the contact area of the coil pipe and the barrel after the assembly and the forming is large, the barrel is very difficult to detach, and the coil pipe is easily damaged during spot welding, so that the accurate position of the pitch of the coil pipe cannot be ensured. How to ensure the dimensional accuracy and quality of the coil assembly forming of the radiation section, and simultaneously improve the labor efficiency and reduce the cost becomes an urgent need in the manufacturing process of the radiation section of the molten salt furnace.
