About Carbonitriding Furnace

Carbonitriding Furnace manufactured by United Enterprises is a controlled-atmosphere heat treatment furnace where both carbon and nitrogen are diffused into the surface of steel components to produce a hard, wear-resistant case.

Brief Description:

Carbonitriding combines carburizing and nitriding for better hardenability than pure carburizing on certain alloys useful for gears, shafts, bearings, fasteners and tools. Our carbonitriding furnaces use endo gas with controlled ammonia addition to achieve the right balance of carbon and nitrogen.

Sealed quench (IQF), pusher, mesh belt and pit configurations are available, with multi-zone temperature control, dew point and oxygen probe-based atmosphere management, and PLC / SCADA-based recipe storage.

Each line is engineered around the customers part mix, target case depth and production rate.

Characteristics:

Surface carbonitriding carbon + nitrogen diffusion
Maximum temperature up to 1100C
Sealed quench / pusher / mesh belt / pit configurations
Endo gas + cracked ammonia atmosphere
Available in electric and recuperative gas-fired versions
Carbon and nitrogen potential control via SCADA
In-house atmosphere generators
Designed for high-volume production lines

Our turnkey approach, in-house atmosphere generator manufacturing and CE / ISO compliance serve automotive, gear, bearing, fastener and engineering industries.

FAQs:

Q: When should I choose carbonitriding over carburizing?

A: Carbonitriding is preferred for alloys that need better hardenability than carburizing alone can give, often with shorter cycles.

Q: Atmosphere what controls case quality?

A: A controlled mix of endo gas and ammonia, tightly managed by dew point and oxygen probes via SCADA.

Q: Sealed quench or pusher type?

A: Sealed quench for premium automotive parts; pusher for higher-volume general parts.

Advanced Construction and Materials

Crafted from high-grade alloy steel and insulated with refractory bricks, this carbonitriding furnace is built for longevity and superior thermal efficiency. The use of Kanthal or Silicon Carbide heating elements enables consistent and robust operation in demanding industrial environments.

Comprehensive Control and Uniformity

Features like automatic PID temperature regulation and PLC-based management facilitate precise process control. The furnace provides uniform temperature distribution within 5C, vital for repeatable, high-quality surface hardening. Customized sizes and arrangements ensure compatibility with a range of production scales.

Safety and Reliability Assured

Equipped with over-temperature protection, emergency shutdown capabilities, and robust chamber construction, the furnace guarantees safe and reliable operation. Forced air or optional water quench systems further optimize process flexibility, ensuring both quality and operator safety.

FAQ's of Carbonitriding Furnace:

Q: How does the carbonitriding process work in this furnace?

A: The furnace introduces a controlled atmosphere of ammonia and endo gas, which, at elevated temperatures up to 950C, diffuses carbon and nitrogen into the surface of metal components. This results in enhanced surface hardness and wear resistance after a subsequent cooling or quenching step.

Q: What benefits does the automatic PID controller provide?

A: The automatic PID controller maintains precise temperature settings throughout the batch process. This ensures optimal process conditions, consistent hardening results, energy efficiency, and reduces the risk of overheating or temperature fluctuations.

Q: When should a water quench tank be used instead of forced air cooling?

A: A water quench tank is typically used when a rapid cooling rate is required to achieve specific hardness levels or metallurgical properties. Forced air cooling is suitable for cases where slower, more controlled cooling is sufficient or where minimizing thermal shock is essential.

Q: Where can this carbonitriding furnace be installed?

A: The furnace is designed for industrial use and can be installed in manufacturing plants, heat treatment shops, or specialized metal processing facilities. Its customizable dimensions and configuration allow adaptation to various operational layouts and capacities.

Q: What materials can be treated with this furnace?

A: This furnace is suitable for case hardening ferrous metals such as carbon steels, alloy steels, and similar materials used in automotive, tool-making, and engineering industries. Its uniform temperature and atmosphere control guarantee consistent results across different batch loads.

Q: How does the uniform temperature distribution ensure quality?

A: Temperature uniformity within 5C across the working chamber minimizes variations in hardness and case depth, ensuring that each part undergoes equivalent treatment. This is crucial for achieving predictable mechanical performance and reducing scrap rates.

Q: What is the advantage of the automatic pusher mechanism for loading?

A: The automatic pusher mechanism streamlines the loading and unloading process, reducing manual labor, increasing operational safety, and supporting higher throughput rates. It also enhances consistency by ensuring uniform batch positioning within the chamber.
