Material is pushed bringing-up section by boat pusher, processing materials adds thermal reduction or calcining or sintering etc. process, then, expect boat
Material is pushed to cooling section cooling by pusher, when being cooled to target temperature, opens the second of cooling section and discharging section and puts
Changing door, the second displacement room sent into by material by material boat pusher again, and the second displacement indoor are filled with protective atmosphere (such as nitrogen), when the
When two displacement indoor are full of protective atmosphere, opening out fire door, material removes from discharging section, turns off out fire door.Due to displacement room
In be full of protective atmosphere, the air outside body of heater is difficult to enter the first displacement room, the second displacement indoor, body of heater outer air be more difficult to into
Enter the bringing-up section in body of heater, and then reduce the requirement to protective atmosphere of the body of heater bringing-up section.
The beneficial effect of the push-down reduction furnace of this utility model a kind of band two-way replacement door: the feed end of body of heater and discharge end
If two-way replacement door, form displacement room, and be passed through the protective atmosphere displaced air such as nitrogen continuously, when entering boat or add to displacement indoor
When work material is come out of the stove, can effectively stop stove outer air and enter in stove, spy is applicable to high temperature, oxidizable heat treatment of workpieces.This pushes away
Protective atmosphere is required less than other type industrial furnace by rod-type reduction furnace.
