Brief introduction:

Bogie-type vacuum bright annealing furnace is energy-saving cyclic operation furnace, super energy-saving structure, using fiber structure, power saving 60%. Production using composite high alumina ceramic nail group, cart anti-impact sealing bricks, automatic sealing cart and furnace door, integrated even rail, no foundation installation, placed on the level ground can be used.

Mainly used for copper pipe, copper machine parts, etc. in the vacuum heat treatment with.

Structure:

Furnace shell has steel plate and section steel welded together, the bottom of the furnace body and the cart light rail is connected as one, users do not need foundation installation, only need to be put on the level cement ground can be used.

Furnace lining with all-fiber structure, relative to the brick hearth energy-saving 60% or so, the use of long-fiber spiked carpet as raw materials, the use of special equipment made of 300 × 300 × 300 specifications, and in the processing of the amount of compression left to ensure that the module in the completion of the masonry, each piece of ceramic fiber blocks in different directions of the expansion, so that the modules squeezed each other into a gapless whole, to achieve the effect of complete heat storage, but also the construction of the products Convenient and quick, can be directly fixed to the furnace shell steel plate stainless steel anchor round nail.

Compared with other products, it has the advantages of low thermal conductivity, low heat capacity, excellent corrosion performance, excellent thermal stability and thermal shock resistance, adiabatic, and the anchors are set on the cold side of the furnace body, which improves the fiber's high-temperature strength.

Heating element using high-temperature resistance alloy wire wound into ribbons and spirals, respectively, hanging in the side of the furnace, the door, the back wall and placed on the cart shelves on the wire tiles, and high alumina ceramic nails fixed.

The trolley is equipped with a pressure-resistant and high-temperature cast steel furnace floor, above which a vacuum furnace canister is set aside to place the workpiece. In order to prevent the oxidized skin generated by the heating of the workpiece through the gap between the furnace floor falls into the heating element around the heating element and cause damage to the heating element, so the furnace floor and the furnace body contact with the insert contact. In order to ensure normal use, it is necessary to often blowing cart furnace bottom plate below the skin of oxidation, generally once a week to blow, blowing the furnace bottom plate lifting, compressed air will be the resistance wire groove of the oxidized skin debris blowing clean, pay attention to prevent the oxidized skin stuck in the wire caused by the short-circuit.

Furnace door is installed on the trolley, integrated with the furnace tank, using cart power compression type, this structure of the compression device so that no friction between the fiber plane on the door and the mouth of the furnace cotton, and a limit device to control the stroke, with good performance, long mission characteristics.

The frame of the cart is made of welded steel profiles, and its rigidity ensures that it will not be deformed under full load. Inside with refractory brick masonry, easy to collision parts and load-bearing parts with heavy brick masonry, to enhance the structural strength of the furnace lining, the walking cart adopts the self-propelled structure, driven by the speed reducer drive sprocket wheel walking on the track.

The sealing of the trolley adopts automatic labyrinth structure and soft-contact double sealing, the cart enters into the furnace through the action of cam and roller inclined surface, and then automatically rises up to be sealed. When the cart is opened, the sealing groove falls down automatically, and the sealing sand in the sealing groove does not need to be added frequently after it is filled up. Cart open out, furnace door lift are electric control, equipped with electromagnetic brake, can prevent inertia impact furnace, and chain control, that is, slightly open the door, automatically cut off the heating element, and at the same time to restore the cart walking mechanism power. After the door is closed in place, the power supply of the traveling mechanism of the trolley is automatically cut off and the power supply of the heating element is restored at the same time.
