Product introduction of tilting trolley annealing furnace

Tilting trolley annealing furnace
Product Usage
RT3 series overturning trolley type annealing furnace is a standard energy-saving cycle-type operation furnace with ultra-energy-saving structure and energy saving of 30%. The trolley adopts anti-collision sealing brick, automatic brick turning mechanism, automatic sealing of the trolley and furnace door, and integrated rails, without foundation installation. It can be used by being placed on the horizontal ground and fixed with foundation iron or expansion screws. Mainly used for high chromium, high manganese steel castings, nodular cast iron, rolls, steel balls, 45 steel, stainless steel and other quenching, annealing, aging and heat treatment of various mechanical parts.
Product introduction
The shell of this series of electric furnace is welded by steel plate and section steel, and the bottom of the furnace body is connected with the trolley light rail as a whole. The user does not need foundation installation, and only needs to be placed on a flat concrete floor.
The furnace lining uses high quality refractory bricks as the furnace lining, which saves about 30% of energy compared to traditional brick furnaces. Long fiber thorn blankets, diatomaceous earth bricks and vermiculite powder are used as insulation materials. High aluminum pressure-resistant brick. In addition to adopting a labyrinth refractory material between the furnace body and the trolley of the electric furnace, a self-operated sealing mechanism is used to reduce the heat radiation and convection loss of the electric furnace, and to improve the uniformity of the furnace temperature.
The heating element is spirally wound with high-temperature resistance alloy wire, and is distributed on the side of the furnace, the furnace door, the back wall and the wire-laying brick of the trolley, and fixed with the national standard socket brick, which is simple.
The trolley is equipped with a pressure-resistant and high-temperature-resistant cast steel furnace floor to carry the workpiece. In order to prevent the scale generated after the workpiece is heated from falling into the surrounding of the heating element through the gap between the furnace floor and causing the heating element to be damaged, the contact place of the furnace floor and the furnace body is inserted. In order to ensure normal use, the oxide scale under the furnace bottom plate of the trolley needs to be purged frequently. Generally, it is blown once a week. The furnace bottom plate is hoisted during the purging, and the oxide scale debris in the resistance wire groove is cleaned with compressed air. Take care to prevent short-circuiting of the oxide pickup in the furnace wire.
The furnace door device is composed of a furnace door, a furnace door lifting mechanism and a furnace door pressing device. The furnace door shell is a solid frame structure welded by section steel and sheet materials, and is laminated with refractory fiber pressing modules. It requires good insulation performance and light weight. The hoisting device of the furnace door adopts an electric device, which is mainly composed of a furnace door frame, a furnace door lifting beam, a reducer, a sprocket, a drive shaft and a bearing, etc. . The furnace door lifting reducer is also equipped with a brake device, which can effectively prevent the furnace door from being displaced during the lifting process. Furnace door compaction device adopts domestic advanced spring-type compaction structure. When the furnace needs to be lifted, the self-weight of the furnace door automatically releases the furnace door through the lever and moves horizontally after a distance to rise. When the furnace door is lowered into place, the furnace door When the pulley placed on the trolley needs to be compressed, the door of the furnace is horizontally moved to a tightly sealed state by the lever of the spring force. The compaction device of this structure makes the fiber plane on the furnace door and the cotton of the furnace mouth. There is no friction between them, which has the characteristics of good performance and long use mission.
The frame of the trolley is welded by profile steel, and its rigidity is guaranteed not to deform under full load. The interior is made of refractory bricks, and the easy-to-collision parts and load-bearing parts are made of heavy bricks to enhance the strength of the furnace lining structure. The carriage of the trolley adopts a self-propelled structure.
Trolley seal adopts automatic labyrinth structure seal. The trolley enters the furnace and is sealed by the cam and roller ramp. When the trolley is driven out, the sealing groove is automatically dropped. After the sealing sand in the sealing groove is filled up, it is not necessary to add it frequently. When the trolley is out, the furnace door is lifted and controlled electrically, equipped with an electromagnetic brake to prevent inertia from hitting the furnace body, and chain control, that is, after the furnace door is slightly opened, the heating element is automatically cut off and the power of the trolley walking mechanism is restored. After the furnace door is closed in place, the power of the trolley travel mechanism is automatically cut off and the power of the heating element is restored.
Overturning hydraulic mechanism: It adopts a combination of motor, plunger pump, solenoid valve, hydraulic oil cylinder, etc. to form a hydraulic power overturning mechanism, which is controlled by electric buttons in the control cabinet, and is equipped with an anti-overturning device to ensure convenient use.
