1.Application
The tilting type bogie hearth furnace is mainly used for quenching, annealing, aging of high chromium and high manganese steel castings, nodular cast iron, rolls, steel balls, 45 steel, stainless steel and heat treatment of various mechanical parts.
RT3 series turnover tilting type trolley electric resistance heat treatment furnace is a standard energy-saving periodic operation furnace with super energy-saving structure and power saving of 30%.The trolley adopts anti-collision sealing brick, automatic overturning 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.

3.Structure Introduction
The shell of this series of electric furnace 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 basic 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 30% energy compared with the traditional brick furnace. Long fiber thorn blanket, diatomite brick and vermiculite powder are used as thermal insulation materials. The furnace mouth adopts heavy anti-collision brick 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 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 is 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 workpiece.
The furnace door device is composed of furnace door, furnace door lifting mechanism and furnace door pressing device.
The trolley frame is formed by welding section steel, and its rigidity ensures no deformation under full load.
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:The furnace for heat treatment system adopts energy saving fiber cotton as furnace lining, and the energy-saving effect is more obvious, up to about 30%.
