AI Technical Summary
In existing water quenching devices, the water consumption for external spraying is greater than that for internal spraying. After prolonged use, the external spray pipe is prone to clogging, resulting in uneven quenching, overflow, and energy waste, which fails to meet the requirements for the performance stability of steel pipes.
The water quenching energy-saving device adopts a combined internal spray and external spray circulation pressurization system. Through the coordinated operation of the internal spray pump and the external spray pump, the coolant is recycled and reused in a grid-connected manner. Combined with the support mechanism and regulating valve control, it ensures a stable supply and reuse of coolant, prevents nozzle splitting, and improves the stability of external spray.
This technology enables efficient use of coolant, avoids overflow and flow interruption, ensures the stability of steel pipe quenching performance and energy conservation, and fills the gap in the semi-immersion water quenching process for large-diameter thin-walled pipes.
