The quenching process is an important indispensable link in the production process of plates. It can improve the internal molecular stress of the pipes and enable the plates to reach the required properties. The roller-bottom quenching furnace needs to use a conveying device to convey the pipes for quenching, so as to improve the quenching efficiency.
