Square tube quenching and tempering production line

The square tube quenching and tempering production line adopts the electromagnetic induction heating principle to heat the square tube online and then spray water for quenching and tempering. The whole line applies Siemens PLC control system to make the square tube quenching and tempering process fully automated, intelligent, energy-saving and environmentally friendly, easy to operate, and convenient to produce. It is deeply loved by the steel pipe manufacturing industry.
