Applications

Vacuum Sealed Continuous Working Rotary Tube Furnace is commonly used in the following areas:

• Laboratory calcination and drying of positive electrode materials in batteries
• Heat treatment of non strong acid-base powder materials and granular materials in batteries
• High temperature reaction, carbonization, sintering, and pyrolysis of rare earth materials, chemical catalytic materials, magnetic materials, powder metallurgy materials, and nonferrous metal materials
• Powder or granular materials of kaolin non-metallic mineral materials

Features

The Vacuum Sealed Continuous Working Rotary Tube Furnace is a versatile and powerful piece of laboratory equipment that offers a wide range of benefits to users. Here are some of the key features of this product:

• Vacuum sealing technology: This furnace can be vacuum sealed, which allows for the processing of materials in an inert or reducing atmosphere. This is ideal for materials that are sensitive to oxidation or other reactions with the atmosphere.
• Continuous operation:  This furnace can be operated continuously, which means that it can be used for large-scale production or for extended periods of time.
• High temperature accuracy:  This furnace has a high temperature accuracy, which ensures that the materials being processed are heated to the desired temperature.
• Easy operation:  This furnace is easy to operate, even for novice users. The 7-inch touch screen English image interface makes it simple to set up and monitor the furnace.
• Data logging: This furnace can be equipped with data logging capabilities, which allows users to track the temperature and other parameters of the process. This data can be used to optimize the process and ensure that the materials are being processed correctly.

Principle

The Vacuum Sealed Continuous Working Rotary Tube Furnace operates on the principle of continuous material movement through a work tube while maintaining a controlled atmosphere and temperature profile. The furnace tube is typically made of high-purity quartz or alumina and is heated using high-temperature heating elements, such as silicon carbide. The material to be processed is continuously fed into the furnace tube and transported through it by a rotating mechanism. This continuous movement ensures that the entire surface area of the material is exposed to the desired atmosphere and temperature, leading to uniform processing and improved product homogeneity. Vacuum sealing allows for processing under negative pressure or inert gas environments to prevent oxidation or other undesirable reactions.

Advantages

• High efficiency:  The continuous rotary design allows for continuous feeding and discharging of materials, which results in a higher throughput than batch-type furnaces.
• Uniform heating:  The rotating action of the furnace tube ensures that the materials are heated evenly, which results in a more consistent product quality.
• Precise temperature control: The furnace is equipped with a PID temperature controller that provides precise temperature control, which is essential for many applications.
• Vacuum or atmosphere protection: The furnace can be operated under vacuum or atmosphere protection, which allows for the processing of materials that are sensitive to oxidation or other environmental factors.
• Wide range of applications: The furnace can be used for a wide range of applications, including calcination, drying, heat treatment, carbonization, sintering, and pyrolysis.
