这项发明是关于金属的淬火硬化,特别是对如象钢管这样相对移动、长形的轧件进行淬火,并经改进了的喷雾淬火装置。此发明特别适用于长形轧件的感应加热处理。加热了的铁或钠管的喷雾淬火通常是通过环绕管子并使淬火液体向中心直接喷 This invention relates to the quench hardening of metals and, more particularly, to the use of a spray quench device which is relatively quenched, such as a steel tube, quenches the elongated rolled stock. This invention is particularly suitable for induction heating of long rolled products. Spray quenching of heated iron or sodium tubes is typically accomplished by surrounding the tubes and directing the quenched liquid toward the center
