Product introduction & application
Quenching and hardening technology has four stages: first pretreatment to clean the oil and oxide layer on the rail surface. Then enter the heating stage to quickly heat the rail surface. Then cool the rail and put the QU80 QU100 crane rail into the quenching medium. Finally, low-temperature tempering is performed to eliminate internal stress and improve the toughness of the rail.
QU80 QU100 is often used in ports, large-scale projects, dock hoisting and other occasions with high requirements for crane rails. The quenched QU80 QU100 has high strength, high wear resistance and good fatigue resistance, and can adapt to frequent lifting and operation operations.
