Tilting Trolley Fast Quenching Bogie Hearth Car Bottom
Heat Treatment Furnace , Heat Treatment Oven
1. Advantages
The tilting type car bottom heat treatment machine is a standard energy-saving periodic
operation furnace with super energy-saving structure and power saving of 80%. The
trolley adopts anti-collision sealing brick, automatic tilting mechanism, automatic sealing
trolley and furnace door, and integrated rail connection. It does not need foundation
installation. It can be used when it is placed on the horizontal ground and fixed with
the foundation pad iron or expansion screw.Tilting trolley heat treatment furnace is
mainly used for heat treatment of high chromium and high manganese steel
castings, nodular cast iron and rollers, steel balls, 45 steel and stainless steel parts.

3.Structure of Heat Treatment Oven
The tilting trolley furnace shell is welded with steel plate and section steel, and the bottom of the furnace body is connected with the trolley light rail. Users do not need foundation installation, but only need to put it on the flat cement ground.
The furnace lining adopts light refractory brick as the furnace lining, which saves about 80% energy compared with the traditional brick structure furnace. The long fiber blanket, diatomite brick and vermiculite powder are used as thermal insulation materials. The furnace mouth adopts heavy anti-collision bricks and heavy high aluminum anti pressure brick on the trolley surface. In addition to the labyrinth refractory masonry between the electric furnace body and the trolley, the self acting sealing mechanism is also used to reduce the heat radiation and convection loss of the electric furnace and improve the uniformity of furnace temperature.
The heating element of furnace heat treatment of metals is made of high-temperature resistance alloy wire wound into a spiral shape, which is distributed on the furnace side, furnace door, rear wall and trolley wire laying brick, and fixed with national standard socket brick.
The trolley is equipped with a pressure and high temperature resistant cast steel furnace bottom plate to carry the parts.In order to prevent the heating element damage due to oxide scale generated falling into the gap of the bottom plate. The contact between the furnace bottom plate and the furnace body adopts plug-in type. In order to ensure normal use, it is necessary to frequently purge the oxide scale under the bottom plate of the car bottom furnace. Generally, purge once a week. During purging, lift the bottom plate of the furnace and purge the oxide scale in the resistance wire groove with compressed air. Pay attention to prevent the oxide scale from causing short circuit in the furnace wire.
The trolley type heat treatment furnace door device is composed of furnace door, furnace door lifting mechanism and furnace door pressing device. The shell of the furnace door is welded by section steel and plate, with a firm frame structure, which is stacked with refractory fiber pressing modules. It is required to have good thermal insulation performance and light weight.The lifting device of furnace door adopts electric device, which is mainly composed of furnace door frame, furnace door lifting beam, reducer, sprocket, transmission shaft and bearing. The up and down movement of furnace door is driven by the positive and negative transmission on the reducer.The furnace door lifting reducer is also equipped with a brake device, which can effectively prevent the displacement of the furnace door during the lifting process.The furnace door pressing device adopts the domestic advanced spring pressing structure. When the furnace needs to be lifted, the self weight of the furnace door will automatically release the furnace door through the lever and move it horizontally out of a certain distance and then rise. When the furnace door lowers in place and the furnace door needs to be pressed down on the pulley of the trolley, the spring force will move the furnace door horizontally into the compression sealing state through the lever. The pressing device of this structure makes no friction between the fiber surface on the furnace door and the furnace mouth cotton, and has the characteristics of good performance and long service life.
The trolley frame is formed by welding section steel, and its rigidity ensures no deformation under full load.The interior is built with refractory bricks, and the easily collided parts and load-bearing parts are built with heavy bricks to enhance the structural strength of the furnace lining. The trolley adopts self-propelled structure, and the driving sprocket of the reducer drives the walking wheel to walk on the track.The trolley seal adopts automatic labyrinth structure seal. When the trolley enters the furnace, it is automatically lifted and sealed through the action of cam and roller slope.When the trolley leaves, the sealing groove will fall automatically, and the sealing sand in the sealing groove does not need to be added frequently after being filled.When the trolley leaves, the lifting and lowering of the furnace door are electrically controlled, equipped with electromagnetic brake, which can prevent inertia from hitting the furnace body, and interlock control, that is, after slightly opening the furnace door, automatically cut off the heating element and restore the power supply of the trolley traveling mechanism at the same time. After the furnace door is closed in place, automatically cut off the power supply of trolley traveling mechanism and restore the power supply of heating elements at the same time.
Overturning hydraulic mechanism: the hydraulic power overturning mechanism is composed of motor, plunger pump, solenoid valve and hydraulic oil cylinder. The control cabinet is controlled by electric button, and anti overturning device is installed to ensure convenient use.
Note: energy saving fiber cotton can be selected for furnace lining, and the energy-saving effect is more obvious, up to about 60%.
