Gas Pit Type Heat Treatment Furnace For Metal Materials Quenching Tempering Normalizing Annealing

※ Product description:

1. Structural design

1.1 Furnace body: usually a pit structure, the furnace body is provided with a furnace chamber to accommodate the workpiece and the heating medium. The shape and size of the furnace can be designed according to the specific heat treatment process and workpiece requirements.

1.2 Furnace door: The design of movable furnace door is adopted to realize the opening and closing and sealing of the furnace door through a specific mechanism. A trapezoidal first seal bar is installed on the four sides of the furnace door body, a triangular second seal bar is installed on the four corners, a number of sealing racks are installed in the furnace body, and the furnace door is installed on the second traveling mechanism, and the sealing bar and the sealing rack are contacted by the cylinder to achieve sealing, thus changing the furnace volume.

1.3 Walking mechanism: The first walking mechanism is installed at the lower end of the furnace body, which is used to support the furnace body and realize the movement of the furnace body. The first walking mechanism usually includes parts such as a walking wheel, a motor and a walking track, which can make the furnace body move within a certain range and facilitate loading and unloading of workpieces and adjustment of position.

2. How it works

2.1 Heating method: Gas is used as fuel, and the gas is mixed with air through the burner to burn, and the generated heat energy is transferred to the workpiece in the furnace, so that it can reach the required heat treatment temperature. Gas combustion is full, no pollution, heating speed is fast, and the heating temperature can be accurately controlled by adjusting the gas flow and the working state of the burner.

2.2 Principle of variable capacity: Through the movement of the movable furnace door and the coordination of the sealing mechanism, the effective volume of the furnace is changed. When a larger size or number of workpieces need to be processed, the furnace door can be moved outward to increase the furnace volume; When dealing with smaller workpieces, the furnace door is moved inward to reduce the furnace volume, so as to realize the purpose of flexibly adjusting the furnace capacity according to the actual situation of the workpiece, and improve the versatility and energy efficiency of the equipment.

3. Performance characteristics

3.1 High precision temperature control: equipped with advanced temperature control system, such as intelligent digital temperature controller, temperature measuring elements and automatic burner composed of closed-loop control system, can achieve the accurate control of the temperature in the furnace, the accuracy can reach ±1℃ or even higher, to meet the requirements of high-precision heat treatment process.

3.2 Significant energy saving effect: on the one hand, gas combustion efficiency is high, compared with traditional coal heat treatment furnace, can effectively reduce energy consumption; On the other hand, through the waste heat utilization device, such as the heat exchanger, the waste heat of the high-temperature flue gas in the furnace is recovered and used to preheat the air or other media into the furnace, further reducing energy consumption and saving production costs.

3.3 Good environmental performance: Using natural gas and other clean gas as fuel, the emission of pollutants generated during combustion is less, which meets the requirements of modern industry for environmental protection and reduces the pollution to the environment.

3.4 High degree of operation automation: the use of intelligent PLC control or computer automatic control system, can achieve the automatic adjustment and monitoring of the temperature, pressure, gas flow and other parameters in the furnace, simple operation, reduce manual intervention, reduce the labor intensity of the operator, while improving the stability and reliability of the production process.
