Parameters
Tube Mill Forming & Welding & Sizing Section
It is composed of forming part, welding part, cooling part and sizing part.
At first, the forming part has the breakdown, side cluster and fin-pass to consecutively form the strip and the formed strip is melted by TIG welder at the welding part.
The melted part is pressurized by squeeze roll stand to shape the pipe.
The pipe is cooled down as passing through the cooling zone and it becomes a round pipe or angular pipe at the sizing part.
High Precision
Shaft runout ≤ 0.03mm
Ensure stable equipment operation
Real Time Recording
Comprehensive recording and preservation of production line data, traceable to the welding current, solid solution power, current frequency, etc. of each steel pipe
Fast Speed
Ensure that the quality of the welded pipe meets ASME standards, and the speed can reach 7m/min when making 304 16*0.6mm pipes
High Yield
The yield can reach over 98%.
Automatic Water Cut-Off
Perforation alarm and automatic water stop function
ONE CLICK START STOP
With one click start stop function

Tube Mill Bright Annealing Section
Intelligent Bright Annealing Machine
Annealing machine is a specialized equipment used to heat pipes online to the required temperature, and then quickly cool them to below 100 ℃ under gas protection. It plays a role in reducing weld microstructure, refining weld grains, eliminating pipe stress, improving mechanical properties, and enhancing corrosion resistance.
Features
Industry innovation: Insulation resistance monitoring and protection function: If the human body touches the output copper bar, connecting cable bare copper, or inductor conductor, it can protect the shutdown
The remote start function allows the production line to remotely start the power supply online
Water pump circuit breaker trip protection: When the water pump is overloaded, the circuit breaker trips and the equipment protection stops
Low pressure protection for cooling water circulation. When the cooling water circulation pressure is too low, the protection shuts down
Over temperature and low temperature alarm: When we set the high and low temperatures. In the normal production process, there is an alarm output when the temperature is too high or too low
Data collection function: It can generate records of production process parameters and production data, save them in the HMI disk, and trace the data
It can provide an address for the upper computer and read the working status and data of the power supply through the modbus protocol
Temperature curve generation: Temperature curve data can be saved in the HMI interface USB flash drive. As long as the USB flash drive has sufficient storage space, it can be protected for a year
Tunnel movement function: When the device encounters abnormal resistance during operation, the device automatically moves and triggers the protection system
