The invention relates to a
nitriding furnace with a
magnetic field auxiliary mechanism. The
nitriding furnace with the
magnetic field auxiliary mechanism is mainly characterized in that connecting pieces are arranged on two opposite sides in a furnace shell and are each provided with a flat plate-shaped
magnet frame; the two flat plate-shaped
magnet frames are parallel to a center line of a side through hole of the furnace shell; an upper horizontal strip-shaped baffle plate, a middle horizontal strip-shaped baffle plate and a lower horizontal strip-shaped baffle plate are arranged on each
magnet frame and are connected with the magnet frames through fastening pieces; two electromagnets arranged in parallel to form a group and provided with iron blocks in coils are clamped between each baffle plate and the corresponding magnet frame; two
guide wires of each group of
electromagnet coils are connected with a
binding post arranged on a side furnace cover; and the upper groups of electromagnets, the middle groups of electromagnets and the lower groups of electromagnets on two sides of the furnace shell are symmetrically arranged. According to the
nitriding furnace with the
magnetic field auxiliary mechanism provided by the invention, the workpiece nitriding speed can be accelerated, the nitriding time is short, a nitriding cycle is greatly reduced, the process cost is reduced, theworkpiece deformation is reduced, the quality of a nitriding layer is improved, the
nitrogen-containing concentration of the nitriding layer of a workpiece is increased, the
fragility of the nitridinglayer is eliminated, and a
mechanical property of a
surface layer is improved; and the nitriding furnace with the magnetic field auxiliary mechanism is advanced and reasonable in structure, convenient to operate, reliable to operate, and durable in use.
