トンネル窯

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.

製品の特徴 (トンネル窯)

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, 焼結, and cooling zones along the track, enabling large-scale production.

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, holding, and cooling curves to meet the requirements of complex sintering processes.

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.

Wide temperature range, covering various processes

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

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.
