RX3-25-12 Electric Box Type Heat Treatment Furnace — High-Precision Solution for Metal Processing

The RX3-25-12 Electric Box Type Furnace is a premium box type heat treatment furnace designed for professional heat treatment of small and medium-sized metal parts and alloy components. Built with a robust steel structure, high-quality insulation materials, and an advanced electrical control system, this electric bogie hearth furnace provides excellent temperature uniformity, stable performance, and long operational life. It is widely used in metalworking, machining, R&D laboratories, and precision part manufacturing where accurate temperature control is essential.

Reliable Furnace Structure and Efficient Insulation

The furnace body is manufactured using 6–8# sectional steel and 3–12 mm steel plates, delivering high stability and strong durability under long-term heating conditions. The lining adopts high-alumina silicate fiber blocks with a compression density of ≥235 kg/m³, ensuring outstanding thermal insulation, reduced heat loss, and improved energy efficiency. With a maximum temperature resistance of 1250°C, the lining maintains structural integrity even under heavy-duty usage.

Stable Heating Performance with Uniform Temperature Control

The RX3-25-12 features a working chamber of 500 × 500 × 500 mm and provides excellent temperature uniformity of ±10°C, meeting strict industrial heat treatment requirements. The 0Cr27AL7Mo2 resistance alloy heating elements are installed across the side walls and furnace bottom to create an even heat distribution. Combined with a low surface temperature rise (≤50°C), the furnace ensures safe and efficient long-term operation.

Advanced PID Control System for Precision Heat Treatment

Equipped with a Shimaden intelligent temperature controller (Japan), Siemens PLC, and a 10-inch touchscreen, the furnace uses PID regulation with auto-tuning capability for accurate and stable temperature control. Operators can easily set process curves, record temperature data, and monitor furnace conditions in real time. Additional safety systems, including SCR control, ammeters, voltmeters, and automatic air switches, ensure reliable operation of the entire heat treatment process.
