Baoding Sanzheng Electrical Equipment Co., Ltd. was established on March 10, 2017, with a registered capital of RMB 55.5 million. The company is located in the Baoding National High-tech Industrial Development Zone with convenient transportation and beautiful environment, covering an area of 26640 square meters. SANZHENG is a professional manufacturer of high-tech modern induction heating products that integrates research and development, production, and application. SANZHENG is committed to the design and manufacturing of induction heating equipment, with products widely used in the industries of steel, machinery, building materials, automobiles, metallurgy, power, photovoltaic, petroleum, chemical, semiconductor manufacturing, etc.
The induction heating equipment for non-ferrous metal heat treatment is mainly applied in the fields of annealing, forging and smelting of various tubes, bars, wires and strips. The on-line heat treatment of non-ferrous metals has the advantages of good controllability, high efficiency and energy saving, safety and environmental protection, etc. It can effectively improve the physical characteristics of non-ferrous metal materials and is superior to the traditional production process.
Solid solution treatment of stainless steel and titanium pipes
Application scope |
It is used for on-line bright annealing and black annealing of stainless steel pipes, titani um pipes, tantalum pipes, etc. |
Technical features |
Fast heating speed, high efficiency, and significant energy saving effect |
Effectively restore the weld organization, refine the weld grain, eliminate pipe stress, thereby improving the mechanical properties of metal materials, and enhancing the corrosion resistance. |
The full digital solid-state induction heating power supply has perfect protection functions, ensuring reliable operation and a low failure rate. |
By adopting PLC + HMI and a high-precision thermometer to achieve closed-loop control of temperature/speed, it can precisely control the heating temperature and realize fully automated production along the whole line. |
It is equipped with a hydrogen, nitrogen/argon pressure monitoring system, an intelligent ignition and flame monitoring system, and an infrared intelligent temperature measuring system. |
The on-line annealing power is combined with the pipe production process. By calling the database, all types of pipes can be produced. |
Process requirement |
Materials: Titanium alloy, 300 series austenite, 400 series ferrite, duplex steel, tantalum, etc. |
Pipe diameter: Ф6 - 219mm |
Heating temperature: Stainless steel pipes: 1050ºC- 1150ºC; Protective gas: Hydrogen or a mixture of hydrogen and nitrogen Titanium pipes: 700ºC- 850ºC; Protective gas: Argon Tantalum pipes: 1000ºC-1250ºC; Protective gas: Nitrogen |
Heating power supply Power: 50 - 600kW Frequency: 8 - 200kHz (The power and frequency of the heating power supply shall be matched according to the pipe diameter, thickness and production speed.) |
