1. Its purpose is to: 1. Reduce hardness and improve machinability. 2. Eliminate residual stress, stabilize size, reduce deformation and crack tendency. 3. Refine the grains, improve the structure, and eliminate the defects of the structure. 4. Homogenize material organization and composition, improve material properties and prepare for subsequent heat treatment. The seamless steel pipe annealing furnace is to heat the steel pipe to a temperature slightly higher than Ac1, and after holding for a certain period of time, it is cooled to 550 ° C ~ 600 ° C and the heat treatment process with air cooling is called stress relief seamless steel tube annealing.

2. The seamless steel tube annealing furnace is professionally designed and customized by Shaanxi Haishan Electromechanical Co., Ltd. for users. Haishan Electric Furnace has several successful cases of seamless steel tube annealing furnaces. The furnace has good temperature uniformity and stable and reliable performance. Steel tube annealing furnace. Haishan Electromechanical Xiaobian recommends this seamless steel pipe annealing furnace to everyone

1. Product name: seamless steel pipe annealing furnace

2. Workpiece material: carbon steel alloy steel workpiece

3. Diameter range: diameter 10mm～406mm

4. Workpiece length range: greater than 2m

5. Intelligent intermediate frequency power supply series: KGPS160KW-8000kW

6. Power consumption: Calculated according to the customer’s workpiece material and diameter, heating temperature, running speed, etc.

3. The seamless steel pipe annealing furnace adopts the intermediate frequency heating device, which is specially designed for the seamless steel pipe continuous annealing furnace. According to the characteristics of its heating in motion and the heated workpiece being a seamless steel pipe, the intermediate frequency power supply and the inductor are designed in the system. The parameters have been specially designed, and the whole set of seamless steel pipe annealing furnace production line equipment system is controlled by a separate power supply, and the performance is stable.

Fourth, the seamless steel tube annealing furnace adopts digital power supply and its characteristics:

1. Digital constant power control system (highly integrated control circuit)

2. The program has various protection functions (overcurrent, overvoltage, water pressure, phase loss, undervoltage, overload)

3. The seamless steel tube annealing furnace has low failure rate and simple operation

4. Long-term work without temperature drift, stable working point and high performance

5. The main circuit gets rid of the cumbersome startup circuit and relay circuit, the failure rate is low, and the startup success rate is high

6. The standard cabinet is used to make the assembly reasonable, realize the standardization of the intermediate frequency power supply, and the circuit is beautiful.

7. The adjustment curve is smooth, the linearity is high, and there is no impact, and the matching is adjusted according to the change of the load, and the seamless steel pipe annealing furnace saves electric energy.

5. The manufacturing process of the inductor of the seamless steel pipe annealing furnace: the ratio of the inner diameter of the seamless steel tube annealing furnace inductor to the outer diameter of the workpiece is within a reasonable range, which is designed according to the process parameters of the induction heating furnace provided by the user. The inductor coil is made of large cross-section T2 rectangular copper tube after annealing, winding, pickling, water pressure test, baking, drying, knotting, assembly and other major processes, and then fixed as a whole, the entire inductor is completed. After forming into a rectangular parallelepiped, its vibration resistance and integrity are good. Both ends of the sensor are protected by water-cooled furnace mouth copper plates, which can effectively prevent electromagnetic radiation from harming operators.

6. After-sales service of seamless steel pipe annealing furnace:

1. The warranty period of the seamless steel pipe annealing furnace is 1 year from the date of the equipment leaving the factory, and a lifetime warranty after 1 year.

2. During the warranty period, if the seamless steel pipe annealing furnace has quality problems caused by defects in design, process or materials, it will be repaired free of charge.
