RQ-3-500-9 Gas Pit Type Carburizing Furnace Heat Treatment Furnace 

WUXI WONDERY INDUSTRY EQUIPMENT CO., LTD. introduces the RQ-3-500-9 Gas Pit Type Carburizing Furnace, a versatile and efficient industrial furnace designed for gas carburizing of various large and medium-sized components. With an effective working size of φ3000×1500mm and a rated power of 500 KW, this furnace provides an optimal balance between capacity and energy efficiency, delivering superior temperature uniformity, precise carbon potential control, and operational reliability for demanding heat treatment applications.

Key Technical Parameters:

The furnace features a durable vertical shaft design with a 310S stainless steel inner liner and 300mm thick refractory fiber compressed block insulation for excellent thermal efficiency. The advanced control system is built around a 15-inch industrial touchscreen that enables fully automated management of temperature, carbon potential, process timing, and dripping media (methanol, kerosene). The system integrates Japanese Shimaden SRS13A PID temperature controllers with a German Siemens PLC-based carbon potential control module, ensuring temperature stability within ±1°C and carbon potential stability within ±0.02%CP.

WUXI WONDERY INDUSTRY EQUIPMENT CO., LTD. has equipped this furnace with high-quality components including a 37KW variable-frequency hot air mixing blower, a shared gantry lifting mechanism for the furnace cover, and an advanced oxygen probe system with anti-carbon-clogging features. The furnace is specifically designed for applications requiring medium-depth carburizing with effective hardened layer depths ranging from 0.30mm to 6.0mm, making it ideal for industrial heat treatment of automotive, machinery, and tooling components.

This medium-capacity pit-type gas carburizing furnace represents the perfect combination of robust construction, precise automation, and energy-efficient operation. WUXI WONDERY INDUSTRY EQUIPMENT CO., LTD. has engineered this system to provide manufacturers with reliable, versatile heat treatment capabilities that ensure consistent quality and optimal production efficiency for a wide range of industrial applications.
