Product introduction of key technology of trolley gas heat treatment furnace
Natural gas trolley furnace trolleys are all made of cast parts to ensure the car body is not deformed and durable. The furnace car and furnace lining are sealed by an automatic compaction structure. The opening and closing of the side seal is interlocked with the furnace car in and out.

The furnace body frame is welded by combining various large and medium-sized steels on site. The shell sealing plate is a color steel plate. The high-aluminum all-fiber refractory silk blanket module is a furnace lining, which has a significant energy-saving effect. The bogie frame is welded from various large I-beams, channel steels, angle steels and thick steel plates. The trolley is driven reliably. The drive system uses a motor-reducer. The installation method is shaft-mounted. The structure is compact, the assembly is firm, the access is flexible, the operation is simple, and the maintenance is convenient. The refractory masonry of the trolley adopts high-alumina shaped brick structure, which has good sealing effect with the furnace body and high compressive strength. Horns are placed on the trolley surface for stacking workpieces.

1. The temperature of the trolley gas furnace is uniform, and the workpiece is evenly heated;

2.The gas furnace has a large loading capacity and high productivity, which is suitable for tempering and preheating of various types of parts;

3.The gas furnace lining adopts a full-fiber structure, which improves the insulation performance of the furnace body, saves energy and reduces production costs;

4.The gas furnace is convenient to load the royal material and the operating conditions are good;

5.The trolley-type gas stove is equipped with a chain protection device to prevent malfunctions and accidents due to misoperation;

6. No pollution, good environmental protection benefit of fast quenching furnace. The equipment uses various types of combustion gases as the medium and is heated by various types of burners, with a maximum temperature of 1200 ° C.

Key technologies:

1. All-fiber composite furnace lining.

2. The trolley adopts automatic wheel travel and electric lifting furnace door, which is stable and reliable.

3. All joints of the furnace are soft-sealed, and the gas furnace furnace mouth adopts a flexible pneumatic (electric) compression type seal; the side seal is sealed by a pneumatic fiber soft mechanism. Ensure the tightness of the furnace body.

4. Adopt centralized smoke exhaust system.

5. The furnace door adopts flexible connection of light mechanism to prevent the furnace door from deforming.

6. The combustion system adopts distributed temperature control, and the industrial computer performs centralized management and monitoring, and has both automatic and manual functions. The deviation of the temperature control accuracy indication at the end of the furnace insulation period: ≤ ± 5 ℃.

7. Automatic temperature control mode and zone: pulse combustion, manual and automatic temperature control system. Every two diamond drill bits are a section. The temperature control system converts the controller output signal into the switching time of the gas burner in the gap working state, and the action signal has a linear relationship with the burner output power.

8.Using gas furnace automatic pressure control system, air pressure automatic control system, propane gas pressure control system, gas zone heat treatment furnace multi-zone temperature control system, high-speed burner automatic control system, comprehensively control the furnace conditions, and achieve good temperature uniformity And ensure the safe operation of the furnace.

9. Smoke exhaust method: exhaust smoke after the furnace, through the air heat exchanger (air preheating temperature ≤ 300 ℃), and finally enter the steel chimney to exit the workshop.

10. The entire system of the heat treatment furnace, including gas, compressed air, combustion air, mechanical transmission, furnace pressure and smoke exhaust system, is equipped with chain protection, alarm, metering, automatic adjustment, etc. to ensure the safe operation of the furnace.
