Key Technology
The first roller direct quench system in China
◆Multiple pinch rollersarearranged in the DQ area
◆Each group is individually controlled
◆Max. lifting stroke 750 mm
◆Max. constraint force 15 ton
◆Constraint thin plate flatness
◆15-50mm gauge plate by DQ
◆Realize the production of 07MnNiDVR,N800CF,X70MO specification deep-sea pipelinesteel, EH47,NM500,Q690E andother varieties
High water pressure, small diameter nozzle, staggered jets is beneficial to enhance the cooling intensity and improve the cooling uniformity.
Developed series of cooling equipment, such as high density round nozzles by experiment and numerical simulation.
Round nozzles development
Application of round nozzles
High-density header
◆ 8~10 rows of nozzles, over 1000 quantities
◆ 0~30°jet angles
◆ 0.2~0.5MPa jet pressure
◆ multi-layers damping structure
◆ water crown structure
◆ Edge cooling flux control, etc
Water crown is used to control cooling uniformity along the plate width direction
Committed to building a world-class production base for heavy-duty structural parts
