Natural Gas Bogie Hearth Furnace for Ceramic Product Heat Treatment with 1300℃ and 4000 × 2000 × 2000 mm Chamber

High-Performance Natural Gas Bogie Hearth Furnace RT3Q-200-13 for Ceramic Product Heat Treatment

The Natural Gas Bogie Hearth Furnace RT3Q-200-13, manufactured by WUXI WONDERY INDUSTRY EQUIPMENT CO., LTD., is a high-efficiency periodic heat treatment furnace engineered specifically for the firing, sintering, and thermal processing of ceramic products. With a spacious effective chamber size of 4000 × 2000 × 2000 mm (L×W×H), this furnace supports large-volume batch loading and multi-layer stacking, significantly boosting productivity in industrial ceramic processing lines.

Designed as a natural gas bogie hearth furnace, the system features a kiln car structure that allows operators to load workpieces directly onto the kiln car and transport them smoothly into the furnace chamber. This simplifies material handling, enhances operational efficiency, and enables stable batch heat treatment cycles. Suitable for indoor facilities with ≤85% humidity and a 40 KVA power supply, the RT3Q-200-13 offers robust adaptability across a wide range of ceramic manufacturing environments.

The furnace operates at a rated temperature of 1350°C, with a steady working temperature of 1300°C, meeting the thermal requirements of most high-performance ceramic materials. Using natural gas as its primary fuel, the system adopts dual-side heating with two-stage combustion control to ensure uniform temperature distribution, fast heat-up, and highly efficient fuel utilization. Average gas consumption is approximately 100 m³/h, offering a cost-effective and energy-saving option for large-scale industrial operations.

Technical Parameters – RT3Q-200-13 Natural Gas Bogie Hearth Furnace

The furnace shell is constructed from high-strength steel plates and structural sections, treated with electrostatic powder coating for improved corrosion resistance. Its thermal insulation system consists of 1500°C chromium-containing ceramic fiber modules, polycrystalline mullite fiber, and lightweight insulation layers. This multi-layer refractory design ensures excellent insulation performance, minimizing heat loss and supporting rapid heating and cooling cycles—key for precision ceramic heat treatment.

Inside the chamber, upper and lower arranged burners deliver balanced heating, while silicon carbide furnace bottom plates provide superior thermal conductivity and long service life. Reaction-sintered silicon carbide support columns with multiple height positions allow flexible stacking of ceramic products.

Safety and automation are major strengths of the RT3Q-200-13 furnace. The system includes automatic ignition, flame detection, gas pressure monitoring, exhaust frequency control, and comprehensive interlock protection. In cases of flameout, abnormal pressure, or fan malfunction, the furnace automatically executes alarm and shutoff procedures.

The integrated PLC-based intelligent control system—paired with an AI regulator and a 15-inch touchscreen HMI—provides precise firing curve control, PID tuning, real-time temperature monitoring, and automatic data recording. Five thermocouples ensure accurate multi-point temperature feedback, guaranteeing consistent thermal uniformity for high-quality ceramic sintering.

With its advanced combustion system, superior insulation design, and intelligent automation, the RT3Q-200-13 natural gas bogie hearth furnace from WUXI WONDERY INDUSTRY EQUIPMENT CO., LTD. delivers reliable, efficient, and precise heat treatment performance for modern ceramic production facilities.
