The structure features of gas annealing furnace are as follows

1. The gas annealing furnace takes the gas medium as the heat source, and is heated through the gas burner, with the temperature of 1200 ℃

2. The framework of gas annealing furnace body is welded by steel structure, and the shell sealing plate is steel plate

3. Annealing furnace frame is composed of various large I-steel, channel steel, angle steel, thick steel plate and other materials.

4. The trolley drive has compact structure, firm assembly, flexible access, simple operation and convenient maintenance.

5. The furnace door is made of high aluminum fiber fire-resistant silk blanket, electric hoist lifting, furnace door sealing and locking mechanism.

6. The chimney is equipped with automatic furnace pressure control valve, which can adjust the cooling rate.

7. High speed burner is used for heating, which is evenly distributed on both sides; combustion is controlled by solenoid valve and proportion.

8. The control system is mainly used to adjust and control the flow of gas pipeline, flue gas flow and dilution air volume of each furnace through the detection of temperature and pressure of natural gas annealing furnace, and is equipped with a quick cut-off device for natural gas main pipe. The temperature of the furnace is controlled by different zones. Each zone is equipped with a thermocouple. The temperature is measured and entered into the multi-point recorder to track and record the temperature in the furnace.

9. At present, natural gas trolley furnace is divided into pulse type and regenerative type.

Overview and structural characteristics of gas annealing furnace

Overview: gas annealing furnace is one of the periodic industrial electric furnaces. Gas annealing furnace is mainly used for various large metal or alloy workpieces and large batch annealing heat treatment. It uses natural gas or gas as the medium for combustion and heating, with advanced control and high precision. The combustion and control system consists of air supply pipeline system in front of nozzle, compressed gas pipeline system in front of nozzle, gas pipeline system in front of nozzle, sub high speed burner, ignition control system in front of furnace and temperature control system. Different temperature controllers control different burners to realize large and small fire combustion and automatic control of annealing temperature. Equipped with multi-channel color paperless recorder, it can directly communicate with the upper computer to monitor the temperature of each point in the gas annealing furnace in real time.

The above explains the concept of gas annealing furnace and its structural features in the working process.
