Because of the short procedure

high product quality and near zero pollution

multistage continuous heat-type vacuum furnace is widely used in the separation of binary alloys.However

it is difficult to measure temperature in vacuum furnace

and temperature control level is low with low efficiency.Meanwhile

many problems in vacuum furnace temperature field can not be understood deeply.Using simulation to calculate temperature at each node in vacuum furnace

it is very important to separate different alloys.Finite element analysis was used to understand temperature field in multistage continuous vacuum heat furnace

and temperature field distribution was simulated by the ANSYS software for vacuum furnace in the continuous heating furnace to present simulation distribution map of non-steady temperature field in the furnace with charge free.Through an experimental test

the actual temperature value at the primary node in the chamber was given.Through comparison with the simulation value

the maximum error is below 4.2%at a given node.
