Large Diameter

Large diameter welded pipe black annealing machine is a special machine for heating the steel pipe to solution temperature and then cool it to room temperature. This machine adopts the advanced induction heating power supply, the new type DSP+IGBT power supply. It uses IGBT inverter, DSP precision control, air-cooling structure( water cooling for induction coil), reduce the loss of system. It has perfect self-protection and self diagnostic function, saves 15% energy comparing with the similar product. It is the first machine that could annealing such large stainless steel welding pipes.

1. No need pre-heating. Comparing traditional black annealing furnace, it only takes 10-15 minutes to reach the exact temperature.


2. No need re-straightening. Using rotary tube delivering structure, there is only tiny deformation after heat treatment. 


3. Automatic uploading tubes, with strict docking of front and rear tube's end.


4. Fully automatic running, saving labor cost.

Every time the finishing tube is rolled, it must go through the process of solution treatment. Ta ensure that the performance of the steel pipe meets the technical requirements. and to provide guarantee for the post-process processing or use. Bright solution treatment process of ultra-long seamless steel pipe has always been a difficulty in the industry.

Traditional electric furnace equipment is large,covers a large area, has high energy consumption and large gas consumption, so it is difficult for realize bright solution process. After years of hard work and innovative development, the use of current advanced induction heating technology and DSP power supply. Precision control of heating temperature to ensure that the temperature is controlled within t2C,to solve the technical problem of inaccurate induction heating temperature control. The heated steel pipe is cooled by "heat conduction"in a special closed cooling tunnel, which greatly reduces the gas consumption and is more environmentally friendly.
