ALLCARB® Furnace
Advantages of BMI LPC Furnaces Using ALLCARB®
-
Ideal for large and dense loads such as gear wheels, crankshafts, or components with blind bores
-
Precise control of surface carbon levels and reduced tolerance in case depth
-
Uses clean process gases, avoiding issues related to traditional hydrocarbon gases (propane/methane)
-
Enables efficient carburising of internal bores, including long cylinders.
LPC Furnace Compatibility
The ALLCARB® low pressure carburising process is compatible with the following BMI furnace series:
-
BMICRO – Compact furnace for lab-scale or R&D
-
B8_T & VSE8_T – Horizontal and vertical vacuum gas quenching furnaces
-
B5_TH & B6_TH – Horizontal vacuum oil quenching furnaces
-
V6_TH – Vertical vacuum oil quenching furnace
-
B5_T – High-temperature vacuum brazing furnace
ALLCARB® is BMI’s patented low pressure carburizing (LPC) process, designed to enhance the surface hardness of steels through precise and controlled carbon diffusion. This advanced thermochemical treatment is performed in a carburizing furnace operating under vacuum and elevated temperatures, delivering superior metallurgical results compared to traditional atmospheric carburizing.
What is Low Pressure Carburising?
Low pressure carburising (LPC) is a modern, clean, and efficient alternative to conventional carburizing methods. It eliminates intergranular oxidation and improves carbon penetration depth and surface uniformity, making it the process of choice for high-value components requiring optimal fatigue and wear resistance.
Key Features of the ALLCARB® Process
