WUXI WONDERY INDUSTRY EQUIPMENT CO., LTD. presents the RT3-85-7 Bogie Hearth Annealing Furnace, a robust and precise industrial oven designed for critical post-weld heat treatment (PWHT), tempering, and annealing processes. Engineered to relieve internal stresses in welded structures, castings, shafts, and pipe fittings, this furnace ensures enhanced mechanical properties, dimensional stability, and corrosion resistance for your metal components. Its bogie (trolley) hearth design allows for easy loading and unloading of heavy or bulky workloads up to 5 tons, streamlining production and improving operator safety. This reliable furnace is built to deliver consistent, uniform results batch after batch, making it an essential asset for workshops, fabrication plants, and heavy machinery manufacturers.

Features & Advantages

• Superior Temperature Uniformity: Equipped with a powerful 2.2KW air-circulating fan and a full-fiber refractory lining, the furnace achieves excellent temperature uniformity of ±10°C throughout the 1200x1200x1200mm workspace.

• Advanced Intelligent Control: Features a Japanese Shimaden 32-segment programmable temperature controller paired with a 10.1-inch touchscreen HMI. This system allows for precise recipe management, real-time data logging for over one year, and USB data export via a 7-inch paperless recorder.

• Energy-Efficient & Durable Construction: The high-quality ceramic fiber insulation (max 900°C) combined with a CrMnN heat-resistant steel hearth plate (30mm thick) ensures minimal heat loss, low power consumption (<10% in empty furnace), and long-term durability under cyclic thermal loads.

• Safe & Automated Operation: Incorporates fully electric operation for furnace door lifting (1-ton hoist) and bogie movement (2.2KW reducer). All actions feature electrical interlocks and over-temperature alarms for enhanced operational safety.

• Reliable Heating System: Utilizes high-resistance 0Cr25AL5 alloy heating elements arranged on sidewalls, controlled by solid-state SCR (Silicon Controlled Rectifier) power regulators for smooth, adjustable power output (1-100%) and precise PID temperature control.
