Mesh belt controlled atmosphere furnace

Introduction

Mesh Belt Controlled Atmosphere Furnace is a continuous production furnace that can operate in both open air and controlled atmosphere environments. It is primarily used in the high-temperature sintering process of electronic components such as thick film circuits, resistors, capacitors, and inductors. The furnace features a selected ceramic fiber heater for rapid response and uniform temperature, a lightweight ceramic fiber insulation for low energy consumption, a mesh belt drive system for stable transmission, and multi independent temperature hot zone control for flexible adjustment. It also offers optional mesh belt ultrasonic cleaning system and center computer control unit. The furnace can be customized to meet specific process requirements, including atmosphere, temperature, and throughput.

Applications

The Mesh Belt Controlled Atmosphere Furnace is a specialized heat treatment system designed for the thermo-chemical processing of small elements. This technology ensures consistent and repeatable results, making it an essential tool in various industrial processes. The furnace operates within a controlled atmosphere, which prevents oxidation and supports surface treatment, enhancing the quality and efficiency of the production process. Here are the main application areas of this product:

• Heat Treatment of Fasteners: Ideal for processing small parts like screws, nuts, bolts, and other elements from the Fasteners group. It is particularly effective for controlled atmosphere hardening, carbonitriding, and carburizing.
• Thermo-chemical Treatment: Suitable for processes that require precise temperature control and a protective atmosphere, such as in the treatment of metal components to enhance their durability and performance.
• Continuous Production Lines: Used in manufacturing settings where continuous processing of materials is required, with capacities ranging from 200 kg to 500 kg per hour, customizable for higher production needs.
• Alternative to Vacuum Furnaces: Offers a lower-cost alternative for materials that can be processed outside of a vacuum, utilizing non-reactive gases to prevent oxidation during the heating process.

Principle

The mesh belt controlled atmosphere furnace adopts a mesh belt as the conveying mechanism, and the workpiece is placed on the mesh belt and heated in a controlled atmosphere environment. The controlled atmosphere is generally composed of inert gases such as nitrogen, argon, and hydrogen, which can prevent the workpiece from oxidizing and carburizing during the heating process. The temperature of the furnace is controlled by a temperature controller, and the heating rate can be adjusted according to the process requirements. The mesh belt controlled atmosphere furnace has the advantages of uniform heating, good temperature control, and high production efficiency, and is widely used in the heat treatment of metals, ceramics, and other materials.

Detail & Parts

Features 

Mesh Belt Controlled Atmosphere Furnaces are specifically designed for heat treatment and thermo-chemical processes, ensuring consistent and reliable results for small components. These furnaces offer a range of features that enhance productivity and quality in manufacturing processes, particularly for elements like screws, nuts, bolts, and other fasteners. Key features include:

• Versatile Atmosphere Control: These furnaces can operate with an endothermic atmosphere generated by an external generator using natural gas or propane, or alternatively, with an internal or external methanol dissociator to produce a tailored atmosphere. This feature allows for precise control over the environment, preventing oxidation and ensuring the cleanliness and integrity of the treated parts.
• Flexible Heating Options: Available with both electric and gas heating systems, these furnaces can be customized to suit specific operational needs and energy preferences, enhancing efficiency and cost-effectiveness.
• Adjustable Capacity: Standard models are designed for capacities ranging from 200 kg to 500 kg per hour, with the option to customize for higher production demands, ensuring scalability and adaptability to various production volumes.
• Temperature Range: Capable of operating in the temperature range from 840°C to 955°C, these furnaces are ideal for processes such as controlled atmosphere hardening, carbonitriding, and carburizing, ensuring optimal treatment conditions for a variety of materials.
• Non-Vacuum Operation: Instead of operating in a vacuum, these furnaces use non-reactive gases to displace oxygen, preventing oxidation and promoting a controlled environment that is both efficient and cost-effective for materials that do not require vacuum conditions.

These features collectively make Mesh Belt Controlled Atmosphere Furnaces a robust and versatile solution for manufacturers looking to enhance the quality and efficiency of their heat treatment processes.

Warnings

Operator safety is the top important issue! Please operate the equipment with cautions. Working with inflammable& explosive or toxic gases is very dangerous, operators must take all necessary precautions before starting the equipment. Working with positive pressure inside the reactors or chambers is dangerous, operator must fellow the safety procedures strictly. Extra caution must also be taken when operating with air-reactive materials, especially under vacuum. A leak can draw air into the apparatus and cause a violent reaction to occur.
