This invention provides a vacuum hydrogen furnace, relating to the technical field of heat treatment equipment for soft magnetic materials and other materials requiring hydrogen reduction. The vacuum hydrogen furnace includes a base frame, furnace shell, furnace door, hydrogen purification and delivery device, and cooling system. In this invention, a vacuum pump unit evacuates the interior of the furnace shell into a vacuum, and then a corresponding amount of purified hydrogen is introduced according to the size of the parts. The hydrogen delivery rate is controlled by a mass flow meter and a pressure sensor. A full hydrogen atmosphere is not required; achieving the material reduction effect is sufficient. The amount of hydrogen used is very small, and because of this small amount, it can be treated and discharged through a commercially available non-combustion hydrogen exhaust system, eliminating the need for combustion and ensuring safety and environmental friendliness. Two sets of linear actuators and a crank rotate the end cap along the connection point of the first and second lugs, effectively closing and opening the end cap and the vent pipe. This prevents heat loss from the furnace shell through the buffer tank during operation and avoids damage to the hydrogen delivery pipe and vacuum pipeline due to high temperatures.
