In recent years, with the rapid growth of domestic transportation vehicles such as automobiles, locomotives, and ships, the demand for 10,000-ton forging equipment production lines has gradually increased in large domestic forging enterprises. The 10,000-ton induction heating equipment (with a single unit capacity of more than 2000 kW) has also become the main target for the design and production of induction heating manufacturers. It requires high power, good reliability, high degree of automation, and can enter the central control room of the 10,000-ton forging equipment to participate in the control of the entire line.
For a long time, 10,000-ton induction heating equipment has been monopolized by foreign manufacturers. After years of technical research and development and practice, Boda successfully produced 2000kW medium-frequency induction heating complete equipment matched with 16t electro-hydraulic forging hammer in 2009. The equipment has been put into normal use, and it is easier to operate and easier to maintain than the imported equipment in terms of maintenance and troubleshooting.
The 10,000-ton induction heating complete equipment provides a green thermal processing environment for forging enterprises, with no pollution and low energy consumption; fast heating speed, high production efficiency, less oxidative decarburization, saving material and forging die cost; for heating forgings The temperature is uniform, the temperature difference of the core watch is very small, the temperature control precision is high, and the product quality and the pass rate are improved. In the 10,000-ton hot forging flow production line, the stability, reliability and safety of induction heating equipment are the guarantee for the normal and stable operation of the entire production line.
The innovation of 10,000-ton induction heating equipment has the following points:
(1) Development, development and application of high power thyristor double rectification parallel resonant frequency converter. The numerical control feedback technology, the original current sharing module and the current automatic balancing circuit can automatically balance the two currents without the need of a high-power current sharing reactor.
(2) Variable pitch design of sensor series and parallel connection. According to the size and size of the blank proposed by the user and the economic indicators to be achieved, the sensor parameters are designed first, and the calculation results are simulated in real time by using the Universal2D/3D design software to adjust and optimize the original data. Boda is the first company in China to use sensor simulation software, and it also leads Boda to gradually move toward technological innovation.
(3) Fully automatic mechanical device, no manual intervention is required for the whole line production.
(4) Accurate temperature closed-loop control, which can monitor the screen to display the induction heating process and process parameters, and track all operations.
The development of this complete set of equipment has successfully broken the monopoly of China's 10,000-ton induction heating field by foreign companies, and has truly created a “Made in China†induction heating device with independent technology property rights, which has far-reaching influence in the world of induction heating. . At the same time, it also represents a new era in which Boda will gradually move toward the technological revolution.
Small Coil Wire
Small coil wire is a reprocessed product from black Iron Wire, galvanized wire and PVC Coated Wire. The small coil wire with many features such as small coil size and weight, easy carrying and using, saving labor and improving efficiency is widely used for industrial sites as binding wire. In addition, sizes of small coil wire are various and can be customized on customer's request.
