सुरंग भट्ठा

A tunnel kiln is a continuous high-temperature furnace where materials are carried by kiln cars that move slowly within a fixed furnace body, achieving a continuous firing process.

The equipment is typically divided into a preheating zone, a firing zone, and a cooling zone. The material travels sequentially through each temperature zone with the kiln car to complete the entire heat treatment process. It is suitable for continuous production scenarios with stable output and fixed processes.

उत्पाद की विशेषताएँ (सुरंग भट्ठा)

1. High-efficiency continuous production via kiln car

This tunnel kiln uses a kiln car loading method. Materials are placed on the kiln car and continuously or intermittently pass through the preheating, sintering, and cooling zones along the track, enabling large-scale production.

2. Multi-zone independent temperature control, precise temperature curves

Multiple independent heating zones are set along the length of the furnace, divided into a preheating section, a high-temperature sintering section, and a cooling section. Each zone can be set with its own temperature, achieving precise control of the heating, पकड़े, and cooling curves to meet the requirements of complex sintering processes.

3. Adjustable kiln car speed, controllable residence time

The kiln car's advancing speed is infinitely adjustable, allowing for flexible adjustment of the material's residence time within the furnace according to material characteristics and process requirements, ensuring consistent sintering quality.

4. Wide temperature range, covering various processes

The maximum operating temperature can be designed according to process requirements, covering 1200℃ to 1700℃.

5. Kiln car materials are optional, with strong load-bearing capacity.

Kiln cars can be selected from refractory brick kiln cars, fiber kiln cars, or lightweight kiln cars according to the sintering temperature and material characteristics. They have strong load-bearing capacity, high temperature resistance, and corrosion resistance. A sealing structure is provided between the kiln car and the furnace body to reduce heat leakage.

अक्सर पूछे जाने वाले प्रश्नों (अक्सर पूछे जाने वाले प्रश्न)

1. What is the difference between a tunnel kiln and a pusher furnace?

Tunnel kilns use kiln cars for conveying and are suitable for larger or heavier products.

2. How heavy can the workpieces be?

From several hundred kilograms to tens of tons. Kiln car size and load capacity can be customized.

3. Can a protective atmosphere be used?

हाँ. Some tunnel kilns can be designed for a protective atmosphere.

4. How do kiln cars return?

After exiting the cooling section, the kiln car returns to the charging area via a side line or underground return line.

5. Is it energy-intensive?

Continuous production, high thermal efficiency, more energy-efficient than batch furnaces.
