GWDL-STCS Bogie Hearth Furnace

GWDL-STCS Bogie Hearth Furnace

The GWL-STCS series bogie hearth furnace, also known as a kiln car tunnel furnace, is a versatile high-temperature industrial system designed for demanding thermal processes. It combines the flexibility of a batch furnace with elements of continuous tunnel kiln design, thanks to its automated bogie car loading system. Workpieces are placed on a refractory-lined car, driven smoothly into the chamber by an electric motor and sealed tightly to minimize heat loss. This design ensures efficiency, stable operation, and reduced labor intensity, making the furnace suitable for both industrial production and research applications.

Features

• Wide temperature options up to 1700°C, adaptable for metal heat treatment, ceramics, and advanced materials.
• High precision temperature control within ±1°C, with programmable curves (30–50 segments).
• Excellent temperature uniformity, supported by multi-zone control and optimized heating elements (resistance wire, SiC, or MoSi₂ depending on model).
• Triple-layer insulation structure with high-alumina fiber and lightweight refractory board, reducing energy consumption by more than 20% compared with traditional designs.
• Automated bogie car system with load capacity from 100 kg to 10 tons, equipped with positioning limit switches for safety and stability.
• Integrated safety system including dual-loop protection, soft start, and alarms for over-temperature, over-current, phase failure, and thermocouple break.

Technical Insight

The furnace shell is a double-layer air-cooled structure, keeping external surface temperatures below 45°C even under long-term operation. Heating elements are selected according to the working range: resistance wires or SiC rods for medium temperatures, and MoSi₂ elements for ultra-high temperatures up to 1700°C. Intelligent controllers with RS485 communication enable remote monitoring and precise process programming.

Applications

The STCL bogie hearth furnace finds wide application across multiple industries:

• Sintering of ceramic materials, including household ceramics, industrial ceramics, insulators, and magnetic components.
• Heat treatment of metallic parts such as annealing, tempering, and normalizing.
• Calcination of catalysts and other chemical materials.
• Processing of glass products requiring controlled heating and annealing.
• Research laboratories and institutes engaged in advanced materials development such as rare earths, phosphors, and electronic ceramics.

Advantages

This furnace integrates precision control, high efficiency, and strong adaptability. It delivers uniform temperature fields, reduces operating costs through improved insulation, and accommodates heavy or oversized workpieces with its robust bogie system. Customization options in size, capacity, and control functions allow GWDLTHERMO to tailor each system to the customer’s process needs.
