Abstract
Systems and methods for quenching an extrudate using an atomized spray of liquid are described. A system includes a billet die at a proximal end configured to accept a billet and form an extrudate, a quench chamber located adjacent to the billet die for receiving the extrudate and comprising at least one pulsed width modulation (PWM) atomizing spray nozzle and a control module in communication with the at least one PWM atomizing spray nozzle and configured to independently control a liquid pressure, a gas pressure, a spray frequency, a duty cycle and flow rate of each at least one PWM atomizing spray nozzle.
Claims21
A metal quenching system having a proximal end and a distal end, comprising:
- a billet die at the proximal end configured to accept a billet and form an extrudate;
- a quench chamber located adjacent to the billet die for receiving the extrudate and comprising at least one pulsed width modulation (PWM) atomizing spray nozzle;
- a control module in communication with the at least one PWM atomizing spray nozzle and configured to independently control a liquid pressure, a gas pressure, a spray frequency, a duty cycle and a flow rate associated with the at least one PWM atomizing spray nozzle;
- and
- a first profile scanner positioned at the proximal end of the quench chamber and a second profile scanner positioned at the distal end of the quench chamber.
