RQ-3-1000-9 Gas Pit Type Carburizing Furnace D3m x 4m , Heat Treatment Furnace 

WUXI WONDERY INDUSTRY EQUIPMENT CO., LTD. presents the RQ-3-1000-9 Gas Pit Type Carburizing Furnace, a high-performance industrial furnace specifically engineered for large-scale gas carburizing applications. With an impressive effective working size of φ3000×4000mm and a rated power of 1000 KW, this furnace is designed to handle substantial workloads while delivering exceptional temperature uniformity, energy efficiency, and precise carbon potential control for various large and medium-sized components.

Key Technical Parameters:

The furnace features a robust vertical shaft design with a 310S stainless steel inner liner and 300mm thick refractory fiber compressed block insulation for optimal thermal efficiency. The advanced control system is centered 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 premium 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 deep-case carburizing with effective hardened layer depths ranging from 0.30mm to 6.0mm, making it ideal for heavy-duty industrial heat treatment of automotive, aerospace, and machinery components.

This large-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, high-volume heat treatment capabilities that ensure consistent quality and optimal production efficiency for demanding industrial applications.
