V6_TH Furnace
Thermochemical Process Options
Each vertical oil quenching furnace can be optionally equipped with advanced surface hardening technologies, including:
-
Carbonitriding
These optional modules enhance flexibility and metallurgical performance for specific applications.
The V6_TH series from BMI is a high-performance range of vertical oil quenching furnaces, designed for the vacuum heat treatment of large and heavy parts. These two-chamber vertical furnaces are a modern, clean alternative to traditional atmospheric pit furnaces.
Ideal for industries handling oversized or high-mass components, the V6_TH vertical oil quenching furnace is particularly well-suited for the treatment of aircraft landing gear, wind turbine gears, and other large-scale mechanical parts.
Industrial-Grade Performance and Benefits
BMI’s vertical furnaces for oil quenching deliver robust performance in demanding industrial environments, with key advantages such as:
-
High productivity for large-scale operations
-
Excellent vacuum levels and temperature uniformity across the load
-
Automated vertical handling ensuring rapid transfer to the oil quenching tank
-
Repeatable and reliable results, thanks to full automation and precise process control
