Abstract: Fault mode and fault tree analysis of the WZC double chamber vacuum oil quenching gas cooling furnace system were carried out in the ways of subsystems and subcomponents. The failure modes and fault tree models of the furnace liner, vacuum system, mechanism and electronic control system were established respectively, the corresponding basic events were summarized, and the minimum cut set of each fault tree was obtained by using Fusel method.

Key words: WZC double chamber vacuum furnace system, fault mode, fault tree analysis
