The laboratory high temperature tube furnace is a heating device designed for precise temperature control and uniform heating, suitable for laboratory environment. High temperature tube furnace is mainly used for heating materials under high temperature conditions, such as sintering, annealing, curing or other heat treatment processes. The characteristic of this furnace is that its furnace body is usually tubular, and the interior can be electric heating elements or gas burners to generate the required heat.

Structure and Working Principle of High Temperature Tube Furnace

The main structure of the high temperature tube furnace is usually made of heat-resistant materials, such as refractory bricks or ceramic fibers, to withstand long-term high temperature working environment. The interior of the furnace body is a long tubular space, and the workpiece is placed in the tube and enters and exits the furnace through a cart, hanging basket or other mechanical device.

Working tube or container: The furnace contains a working tube or container for placing samples and heating treatment.

Heating element layout: The heating elements are arranged around the working tube to achieve the best temperature distribution.

Rapid heating and sealed environment: Due to the small volume of the furnace, the heating speed is fast, and the working tube is sealed to protect the interior from pollution and control the atmosphere.

Heating Method

Electric heating: Heat is generated in the tubular furnace body by electric heating wires or heating belts.

Gas heating: Natural gas or other combustible gases are used to burn in the furnace to generate heat.

Temperature Control

The high-temperature tube furnace is equipped with a precise temperature control system, which can set and maintain the required temperature according to the heat treatment requirements of different materials. Temperature control is usually achieved through thermocouples or other temperature sensors, and is precisely adjusted with a PID controller.

Application Field

The high-temperature tube furnace is a standard equipment in the laboratory and is widely used in various experimental processes such as material heat treatment and crystal growth. In the industry, high-temperature tube furnaces are widely used in materials science, electronics industry, ceramic manufacturing, powder metallurgy and other fields, especially suitable for process flows that require continuous production and automated control.

Technical Features

Double-layer shell structure: adopt double-layer shell structure to improve the insulation effect.

Intelligent program temperature control system: use thyristor control to ensure temperature control accuracy.

Air cooling system: an air cooling system is equipped between the double-layer shells to effectively reduce the surface temperature of the shell.

Vacuum and gas mixing system: combined with standard vacuum and gas mixing systems, it can be pre-vacuumed and nitrogen, argon, etc. can be introduced.

Equipment Advantages

Heat insulation and thermal radiation protection: combined with thermal insulation end plugs and thermal radiation protection covers, reduce heat loss at both ends of the working tube and improve heating efficiency.

Maximize heating length: ensure that most of the working tube is heated to the set temperature and provide a uniformly distributed temperature field.

Equipment Type

Open and closed type and non-open and closed type: the working tube can be placed vertically or horizontally.· Gradient, rotary and swing oscillation: A variety of furnace types are available to suit different experimental needs.

Advantages

Uniform heating: The tubular structure helps to achieve uniform heating of the workpiece.

Energy saving and high efficiency: Since the heat is mainly concentrated inside the tubular furnace, the heat loss is small and the energy efficiency is high.

Flexibility: The heating temperature and time can be adjusted according to different process requirements.

The design and function of the high-temperature tube furnace make it an important equipment in the high-temperature heat treatment process, which can provide a stable and reliable heating environment to meet the needs of various industrial applications.
