A new type of quenching hanger for pit heat treatment furnace has been designed,which is suit-able for heat treatment of pressure vessel cylindrical parts with large height and diameter ratio.Through traditional mechanics caculation method and finite element analysis method,the stress and deformation of quenching hanger are studied,and the strength of hanger is verified.The practical results show that the design of the quenching hanger is reasonable,safe and effective,and the use of this quenching hanger has successfully completed the quenching and tempering heat treatment of cylindrical shell with large height and diameter ratio.
