Vertical atmosphere controllable multi-purpose furnace

The utility model relates to a vertical atmosphere controllable multi-purpose furnace, composed of a heating furnace, a quenching tank, a girder, a furnace running mechanism, a furnace cover elevating mechanism, a material supporting mechanism, a drip injecting system, etc. Workpieces are placed on a furnace cover and are conveyed into the furnace through the elevation of the furnace cover, and the vertical atmosphere controllable multi-purpose furnace can carry out the atmosphere controllable heat treatment. When the utility model is used for quenching, the furnace cover drops down, a material supporting claw is extended out to support the work piece so that the workpieces are fixed in a furnace chamber, the heating furnaceis moved to the just upper part of the quenching tank through the furnace running mechanism and the girder and then is stopped, the workpieces are received by a quenching tank elevating platform, the material supporting claw is retracted so that the workpieces are quenched following the dropping of the elevating platform, and when materials are supported, the material supporting claw is synchronously linked and extended so that the utility model accomplishes the synchronous linkage and retraction of the material supporting claw after the material supporting claw supports the materials.
