Frequently Asked Questions
What are the environmental advantages of VCB vacuum carburizing?
VCB vacuum carburizing produces zero CO2 emissions and eliminates open flames and oil smoke. This creates a clean, eco-friendly working environment that aligns perfectly with green manufacturing initiatives.
How does vacuum carburizing improve workpiece surface quality?
By processing in a vacuum and low-pressure environment, it completely avoids intergranular oxidation and decarburization. This ensures the treated workpieces have bright, clean, and highly uniform surfaces, even for complex geometries.
How does the processing time of vacuum carburizing compare to gas carburizing?
Vacuum carburizing allows for higher processing temperatures (up to 1100°C), which significantly accelerates the process. Consequently, the carburizing time is 1/3 shorter than that of traditional gas carburizing.
What models of the VCB series are available, and what are their capacities?
The common specifications include the VCB-200 (200 Kg capacity), VCB-600 (600 Kg capacity), and VCB-800 (800 Kg capacity), accommodating different production volumes and sizes.
Can the VCB furnace handle complex geometric parts and stainless steel?
Yes. Unlike gas carburizing, vacuum carburizing is highly effective for inner surfaces, holes, and complex geometries. It also enables successful carburizing of stainless steel materials.
