Vacuum Carburizing Furnace EN-CARBO

Product catalog summary

Overview of EN-CARBO Vacuum Carburizing Furnace:
The EN-CARBO NVC Series is designed for high-temperature vacuum carburizing, which significantly reduces carburizing time compared to conventional methods. The furnace operates at temperatures of 930°C, 980°C, and 1040°C, offering flexibility in processing conditions.

Key Features:

Safe and Clean Environment: The flameless operation ensures a safe and clean work environment, eliminating fire hazards and allowing easy integration with production machinery.
Use of Ethylene Gas: Ethylene (C2H4) is used as the carburizing gas, reducing emissions by over 95% compared to traditional gas carburizing and simplifying exhaust system maintenance.
Ease of Operation: The system is user-friendly, requiring no atmosphere control. Carburizing depth is managed by setting time and temperature, with operations controlled via a touch panel.
Cost Efficiency: The cold wall method reduces energy consumption and heat loss, allowing for unattended overnight operation.

Carburizing Quality:
Pulse carburizing and super carburizing enhance fatigue strength and abrasion resistance, producing globular carbide. The process is suitable for high-performance applications, with improved results over conventional methods.

Carburizing Workflow:
The process involves preparation, evacuation, carburizing, diffusion, and quenching, with a typical heat cycle involving pulse carburizing and temperature control.

Automated Line and Quality Assurance:
The NVC series can be integrated into a fully automated line with vacuum degreasing (NVD) and tempering (ERD) equipment. Quality checks include deformation, microstructure, hardness, and durability inspections.

Specifications:
The document provides detailed specifications for various models (NVC-1, NVC-3, NVC-6, NVC-8, NVC-10), including dimensions, heater capacity, and maximum capacity.

Options and Additional Features:

Refining and carbonitriding mechanisms.
Convection heating for reduced soaking time.
Remote monitoring and automated line systems.

Contact Information:
For engineering inquiries, contact the Clean & Thermo-Tech Division in Toyama, Japan. Specifications are subject to change without notice.
