To achieve a wear-resistant surface while maintaining a tough, ductile core in gears, shafts, and heavy-duty steel components, precise carbon potential control is vital. Our Pit-Type Carburizing and Quenching Furnace is engineered to introduce liquid or gaseous organic carburizing agents into a sealed, high-temperature retort, allowing carbon atoms to diffuse evenly into the steel surface. For manufacturers of power transmission parts and mining machinery, consistency in case-hardening depth is crucial; using our advanced Pit-Type Carburizing and Quenching Furnace, our customers consistently achieve uniform carburized layers with precise carbon concentration curves, reducing post-heat treatment failures.
Drawing on our 24 years of manufacturing experience, we design this Pit-Type Carburizing and Quenching Furnace with high-integrity alloy retorts (such as SUS310S or high-nickel alloys) that withstand both high-temperature carburizing atmospheres and thermal shock. Our control systems, trusted by prominent automotive and industrial clients like BYD, integrate oxygen probes and carbon potential controllers to automatically regulate the enrichment gas flow, ensuring stable carburizing levels run after run. We focus on heavy-duty construction and energy efficiency, using premium refractory fiber linings to reduce electricity consumption and lower your overall operational costs.

Application Fields
Gear Case Hardening
Deep-case carburizing of heavy-duty industrial and automotive gears and pinions.
Heavy Shaft Carburizing
Surface hardening of drive shafts, axles, and wind turbine rotor shafts.
Fastener Hardening
Surface carburizing of heavy bolts, pins, and wear-resistant industrial hardware.
Rigorous Quality Control
Our quality assurance practices strictly adhere to the ISO9001 standard. The alloy retorts of our carburizing systems undergo extensive radiographic weld inspections and high-pressure leak testing to ensure absolute gas-tightness under carburizing atmospheres. We configure and test the entire electrical control panel, oxygen probe assembly, and temperature controllers prior to packaging, ensuring the system operates exactly as specified upon arrival.
Packaging & Heavy Shipping
Due to the substantial weight and vertical dimensions of these systems, we package the main furnace body, hydraulic lid lifters, and external quenching tanks separately. The main furnace is secured within a heavy-duty steel skid framework and wrapped in thick waterproof protective sheets. Electrical cabinets are enclosed in custom vacuum-sealed, moisture-proof wooden crates containing active desiccants.
Factory Manufacturing Scale
Since 2002, we have operated a specialized 10,000-square-meter facility in Foshan, China. Backed by a dedicated workforce of 70 employees and a skilled team of 6 thermal engineers, we have delivered more than 1,000 advanced industrial furnaces to customers worldwide. Our extensive project history with leading global brands reflects our ability to deliver highly reliable and long-lasting heat treatment systems.
