In this article, you will get a detailed introduction to the operation guide of horizontal tube furnaces.

Brother Furnace hopes to help you better understand and operate the horizontal tube furnace, to improve the accuracy of your experiments and the efficiency of your production.

What is a Horizontal Tube Furnace

A horizontal tube furnace is a machine designed for high-temperature heating, and its horizontally placed heating tube ensures the uniformity of sample heating. Its main components include the heating tube, temperature control system, furnace chamber, and gas delivery system.

Compared with other types of furnaces, the horizontal tube furnace has the following significant features:

● Uniform heating: As the heating tubes of the horizontal tube furnace are arranged horizontally, the temperature distribution inside the furnace more uniform and reduces the influence of temperature gradient.

● High-temperature stability: such tube furnaces can maintain high temperatures stably and are suitable for experimental and industrial applications that require long heating times.

● Diversified applications: Horizontal tube furnaces have been widely used in the fields of material synthesis, chemical reaction, metal treatment, etc. They are highly adaptable and flexible.

Steps for Using a Horizontal Tube Furnace

1. Installation and Preparation

The first step in using a horizontal tube furnace is to make sure that the equipment is properly installed and prepared:

Choose a suitable location: First you need to choose a dry, well-ventilated place to place the tube furnace. Avoid placing the furnace in a place with high humidity or vibration, which may affect the stability and service life of the equipment.

Power access: Before using, please make sure that the power supply voltage matches the required one and access the power supply correctly according to the instruction manual. Check whether the power cord is intact to avoid electrical failure.

Gas connection: If the experiment requires the use of a specific atmosphere (e.g. nitrogen, hydrogen, etc.), please make sure that the gas piping and connectors are firmly installed and gas-tightness tests are conducted to prevent gas leakage.

2. Temperature Setting and Adjustment

Accurate temperature control is the key to successful use of a horizontal tube heater:

Set target temperature: Enter the desired target temperature through the control panel. Brother Furnace's horizontal tube furnaces are equipped with a high-precision temperature control system that allows for fine-tuning and stable temperature control.

Gradual temperature rise: Avoid rapid temperature rise. Gradual warming is recommended to minimize thermal shock to the sample.

Monitoring and calibration: External thermometers or thermocouples can be used to monitor the temperature in the furnace periodically and calibrate as needed to ensure the accuracy of the heating process.

3. Heating and Experimental Operation

During your operation of the horizontal tube furnace, you need to pay attention to the following aspects:

Sample Placement: Please place the sample evenly in the tube of the horizontal tube high-temperature furnace and make sure that the gap between the sample and the tube is appropriate to promote uniform heating.

Heating process monitoring: After starting the heating, monitor the status of the furnace in real-time and pay attention to changes in temperature and gas flow. Brother Furnace's horizontal tube furnaces have an over-temperature protection function: When the temperature is found to exceed the permissible set point it will automatically cut off the power.

Data Logging: Record key data during the experiment, including temperature, time, and sample status, for subsequent analysis and optimization of experimental conditions.

4. Finish Operation and Cleanup

Correct finalizing operation and cleaning not only help to prolong the life of the tube furnace but also ensure the smooth running of the next experiment:

Cooling: After heating is completed, turn off the heating system and let the furnace and samples cool down naturally to a safe temperature before proceeding with the sampling operation.

Cleaning the furnace tube: Regularly clean the residues and pollutants in the furnace tube to keep the environment inside the furnace clean, which helps to improve the efficiency and life of the equipment.

Problems You May Encounter and Solutions

In the course of using the horizontal tube furnace, you may encounter some of the following common problems. Understanding these problems and their solutions will help ensure the normal operation of the equipment and the smooth running of your experiments:

Unstable Temperature

● Problem: The temperature fluctuates greatly during the heating process and the set temperature cannot be maintained.

● Solution: Check whether the temperature control system is working properly and make sure that the temperature sensor and the heating tube are in good contact. Regularly calibrate the temperature sensor and make sure that there is no problem with the installation position of the heating tube.

Gas Leakage

● Problem: Leaks in the gas delivery system may lead to an unstable experimental atmosphere or a safety hazard.

● Solution: Check all gas connections to ensure good sealing. Use gas detection instruments to check the leakage points. Repair or replace faulty connections and valves promptly. Tube furnaces are designed with gas tightness in mind to provide a safer experience.

Failure of Heating Tubes

● Problem: The heating tube is damaged or aging, resulting in a poor heating effect.

● Solution: Check the condition of the heating tube regularly. When cracks, deformation, or other damages are found the heating tube should be replaced in time. Ensure the use of heating tubes that meet the specifications and avoid overloading. The furnace tubes of Brother Furnace are made of highly durable materials to provide a longer service life.

Pollutants

● Problem: There are foreign materials or pollutants inside the furnace, affecting the experimental results and equipment performance.

● Solution: Clean the inside of the furnace tube regularly to avoid accumulation of residues. Use special cleaning tools and methods to ensure a clean environment inside the furnace. The horizontal tube furnace of Brother Furnace is designed to facilitate cleaning and reduce maintenance difficulties.
