The gas type trolley furnace is mainly used for heating before forging, the furnace door adopts electric lifting type. The trolley adopts double layer frame, heat-resistant cast iron guard plate sprocket driven self-propelled structure. The furnace body of gas trolley furnace is a welding structure of steel frame steel plate furnace shell. The lining at the bottom of furnace wall is refractory castable. PLC intelligent temperature controller is used to manually control three-level temperature control mode. Trolley, all fiber furnace lining, fully sealed furnace body, medium pressure automatic control, medium pressure automatic control, furnace pressure automatic control, combustion automatic control, combustion alarm cabinet display with fault detection positioning; automatic / manual switchable operation system is configured, with low energy consumption high stability. The gas trolley furnace is mainly composed of furnace steel structure, furnace lining, trolley walking mechanism, furnace door lifting mechanism, sealing, combustion, smoke exhaust control system.
1. Steel structure of furnace body: it is made of steel plate section steel by welding. Welding deformation is strictly controlled to make furnace body have good rigidity strength function. Furnace door frame is made of heat-resistant cast iron.
2. Furnace wall lining: the furnace lining of gas trolley adopts fiber lining, which has good heat insulation performance strong anti scouring ability. The surface of the trolley is composed of low cement casting material, thermal insulation brick ceramic fiber felt, the flexible body of ceramic fiber blanket is compressed pneumatically. The rear seal adopts spring to compress the fiber seal block. The low cement casting material on the trolley surface retains expansion joints to ensure that the trolley is strong enough to support the workpiece.
3. The trolley adopts wheel type automatic walking mechanism. The trolley is composed of motor reducer. The driving mechanism is powered by an automatic telescopic cable. The limit switch is set at the back of the trolley far away the heat source. At the same time, a mechanical limiter is welded on the rail. Make sure the equipment is reliable. The trolley has reliable movement, free control long service life.
4. Furnace door lifting: gas trolley furnace equipment furnace door opening closing mode: electric lifting type, driven by multi-functional electric hoist. The furnace door is made of welded steel plate the outer frame is made of heat-resistant stainless steel. The steel structure welded into the frame has little deformation under long-term high temperature conditions. The furnace door is compressed by its own weight, the inclined compression device slide way are installed on the front pillar of the furnace frame, so that the furnace door furnace body are well sealed. The heat insulation layer of furnace door adopts composite fiber structure. The interior of furnace door adopts anti-collision design to prevent damage caused by accidental collision.
5. Sealing: the valve trolley of gas trolley are sealed with fiber flexible seals. The trolley seal adopts the form of flexible sealing block, which has the characteristics of good sealing convenient maintenance.
Labyrinth joint pneumatic compression flexible sealing device are used for the side clearance between trolley furnace body. The mechanism is in the form of leverage. When the trolley enters the furnace, the flexible sealing block with refractory fiber compresses the furnace body under the action of air cylinder. The sealing edge of the heat-resistant cast iron protection plate of the car is used to seal the gap between the two protective covers. prevent high temperature furnace gas overflowing. Air cylinders are installed on both sides of the furnace body the furnace tail, which are connected with a lever used as a lever. The pressure rod raises the sealing groove, so as to compress the refractory fiber sealing knife in the sealing groove, so as to seal the furnace gas. In the case of the seal groove type, the rear seal of the trolley is automatically compressed by the spring. When the trolley is pulled in, the rear of the trolley contacts the seal block connected to the spring. The spring is compressed the trolley is sealed by the reaction force of the spring. The rear sealing device is located on the sealing surface of the side sealing device. The gap between the two corners of the furnace can be sealed by using the side sealing device, the sealing effect is better. The vertical gap between the front end of the trolley the furnace mouth is compressed sealed by fire-resistant fibers welded in the plugs on both sides of the trolley.
