China VCB Vacuum Low Pressure Carburizing Oil Quenching Furnace - Suppliers & Factory for Aerospace and Automotive Applications
Characteristic
01Friendly to the environment, no carbon monoxide/carbon dioxide emissions, clean working environment, no open fire, oil smoke, etc., in line with the development direction of green manufacturing.
Heating and carburizing in vacuum and low pressure environment, no intergranular oxidation, completely avoid oxidation, decarburization, with the best parts surface, beautiful and bright parts after treatment.
For parts dealing with complex geometric shapes, high-demand carburizing and carbonitriding can be achieved, and the carburizing uniformity of the same furnace parts is high.
Vacuum quenching oil, equipped with efficient oil mixing, diversion system, heat exchanger and heater, to ensure quenching stability, cooling rate is fast, to meet the martensitic transformation needs of materials.
Allow carburizing at higher temperature, significantly shorten the processing time, less air consumption, low production and operating costs, especially suitable for deep carburizing or stainless steel and other materials such as vacuum carburizing.
With online char processing function, no need to interrupt the production process, low maintenance frequency, effectively ensure the continuity and stability of production.
The equipment can be convenient to start and stop the furnace according to the actual demand, and the flexibility is very high, suitable for multi-variety and small-batch production.
Integrated PLC, with program controller, touch screen, recorder and other real-time monitoring furnace vacuum degree, temperature, gas flow, pressure and other parameters, support remote fault diagnosis and process tracing.

Comparison between vacuum carburizing and gas carburizing
03| Feature | Vacuum carburizing | Gas carburizing |
|---|---|---|
| Quality |
▶ High concentration carburizing is easy ▶ No grain boundary oxidation and decarburization ▶ The surface of the workpiece with complex geometry is easy to carburize ▶ Stainless steel can be carburized |
High concentration carburizing is difficult Grain boundary oxidation presence (~ 5 nm) It is difficult to carburize the inner surface of the hole Stainless steel carburizing is difficult |
| Cost |
▶ Increased productivity through high temperature and short time treatment (~ 1100℃) ▶ Intermittent operation ▶ Vacuum heat insulation energy saving |
950℃ is the limit During intermittent operation, the furnace temperature and gas are required to be maintained The furnace body continues to release heat |
| Environment |
▶ Zero CO2 production ▶ Good working environment ▶ No large amount of oil smoke emission |
Produce a lot of CO2 High-temperature operation There are a lot of oil smoke emissions |
| Security | ▶ Vacuum and no open flame, so safe | Compared with vacuum carburizing, it is necessary to pay attention to operating procedures |
| Work efficiency |
▶ Carburizing time is 1/3 shorter than gas carburizing ▶ No atmosphere pre-regulation, avoid time waste ▶ No particularly skilled operators required |
Low temperature and long carburizing time The atmosphere needs to be established in advance Skilled and experienced operators are required |
VCB vacuum low-pressure carburizing furnace has become the core equipment of heat treatment in high-end manufacturing industry with its advantages of high precision, low pollution and intelligence. Its technological development is evolving towards higher efficiency, wider material compatibility and deep AI integration, promoting industrial manufacturing to green and precision.
